Abstract

The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of active galactic nucleus (AGN) feedback in a cluster. This proximity allows us to resolve the kinematic impact of feedback on scales down to 5 kpc. Our spectral analysis reveals a high velocity dispersion of km s ⁻¹ near the AGN, which steeply declines to ∼60 km s ⁻¹ between 5 and 25 kpc in the northwest direction. The observed line-of-sight bulk velocity in all regions is broadly consistent with the central galaxy, M87, with a mild trend toward blueshifted motions at larger radii. Systematic uncertainties have been carefully assessed and do not affect the measurements. The central velocities, if attributed entirely to isotropic turbulence, correspond to a transonic intracluster medium at sub-6 kpc scales with 3D Mach number and a nonthermal pressure fraction of . Simple models of weak shocks and sound waves and calculations assuming isotropic turbulence both support the hypothesis that the velocity field reflects a mix of shock-driven expansion and turbulence. Compared to other clusters observed by XRISM to date, M87’s central region stands out as the most kinematically disturbed, exhibiting both the highest velocity dispersion and the largest 3D Mach number, concentrated at the smallest physical scales.

Abstract

We stack 3.75 Ms of early XRISM Resolve observations of 10 galaxy clusters to search for unidentified spectral lines in the E = 2.5–15 keV band (rest frame), including the E = 3.5 keV line reported in earlier low spectral resolution studies of cluster samples. Such an emission line may originate from the decay of the sterile neutrino, a warm dark matter (DM) candidate. No unidentified lines are detected in our stacked cluster spectrum, with the 3 σ upper limit on the m _s ∼ 7.1 keV DM particle decay rate (which corresponds to an E = 3.55 keV emission line) of Γ ∼ 1.0 × 10 ⁻²⁷ s ⁻¹ . This upper limit is 3–4 times lower than the one derived by Hitomi Collaboration from the Perseus observation but still 5 times higher than the XMM-Newton detection reported by E. Bulbul et al. in the stacked cluster sample. XRISM Resolve, with its high spectral resolution but small field of view, may reach the sensitivity needed to test the XMM-Newton cluster sample detection by combining several years worth of future cluster observations.

Abstract

We present results from XRISM/Resolve observations of the core of the galaxy cluster Abell 2319, focusing on its kinematic properties. The intracluster medium (ICM) exhibits temperatures of approximately 8 keV across the core, with a prominent cold front and a high-temperature region ($\sim$11 keV) in the north-west. The average gas velocity in the $3{^{\prime } } \times$ $4 {^{\prime } }$ region around the brightest cluster galaxy (BCG) covered by two Resolve pointings is consistent with that of the BCG to within 40 km s$^{-1}$ and we found modest average velocity dispersion of 230–250 km s$^{-1}$. On the other hand, spatially resolved spectroscopy reveals interesting variations. A blueshift of up to $\sim$230 km s$^{-1}$ is observed around the east edge of the cold front, where the gas with the lowest specific entropy is found. The region further south inside the cold front shows only a small velocity difference from the BCG; however, its velocity dispersion is enhanced to $\sim$400 km s$^{-1}$, implying the development of turbulence. These characteristics indicate that we are observing sloshing motion with some inclination angle following BCG and that gas phases with different specific entropy participate in sloshing with their own velocities, as expected from simulations. No significant evidence for a high-redshift ICM component associated with the subcluster Abell 2319B was found in the region covered by the current Resolve pointings. These results highlight the importance of sloshing and turbulence in shaping the internal structure of Abell 2319. Further deep observations are necessary to better understand the mixing and turbulent processes within the cluster.

Abstract

The dynamics of the intracluster medium (ICM), the hot plasma that fills galaxy clusters, are shaped by gravity-driven cluster mergers and feedback from supermassive black holes (SMBHs) in the cluster cores. XRISM measurements of ICM velocities in several clusters offer insights into these processes. We compare XRISM measurements for nine galaxy clusters (Virgo, Perseus, Centaurus, Hydra-A, PKS 0745–19, A2029, Coma, A2319, and Ophiuchus) with predictions from three state-of-the-art cosmological simulation suites, TNG-Cluster, the Three Hundred Project GADGET-X, and GIZMO-SIMBA, that employ different models of feedback. In cool cores, XRISM reveals systematically lower velocity dispersions than the simulations predict, with all 10 measurements below the median simulated values by a factor of 1.5–1.7 on average and all falling within the bottom 10% of the predicted distributions. The observed kinetic-to-total pressure ratio is also lower, with a median value of 2.2%, compared to the predicted 5.0%–6.5% for the three simulations. Outside the cool cores and in non-cool-core (NCC) clusters, simulations show better agreement with XRISM measurements, except for the outskirts of the relaxed, cool-core cluster A2029, which exhibits an exceptionally low kinetic pressure support (<1%), with none of the simulated systems in either of the three suites reaching such low levels. The NCC Coma and A2319 exhibit dispersions at the lower end but within the simulated spread. Our comparison suggests that the three numerical models may overestimate the kinetic effects of SMBH feedback in cluster cores. Additional XRISM observations of NCC clusters will clarify if there is a systematic tension in the gravity-dominated regime as well.

Context. Accurate X-ray spectroscopic measurements are fundamental for deriving basic physical parameters of the most abundant baryon components in the Universe. The plethora of X-ray observatories currently operational enables a panchromatic view of the high-energy emission of celestial sources. However, uncertainties in the energy-dependent calibration of the instrument transfer functions (e.g. the effective area, energy redistribution, or gain) can limit - and historically, did limit - the accuracy of X-ray spectroscopic measurements.

Aims. We revised the status of the cross-calibration among the scientific payload on board four operation missions: Chandra, NuSTAR, XMM-Newton, and the recently launched XRISM. XRISM carries the micro-calorimeter Resolve, which yields the best energy resolution at energies ≥2 keV. For this purpose, we used the data from a 10-day-long observational campaign targeting the nearby active galactic nucleus NGC 3783, carried out in July 2024.

Methods. We present a novel model-independent method for assessing the cross-calibration status that is based on a multi-node spline of the spectra with the highest-resolving power (XRISM/Resolve in our campaign). We also estimated the impact of the intrinsic variability of NGC 3783 on the cross-calibration status due to the different time coverages of participating observatories and performed an empirical reassessment of the Resolve throughput at low energies.

Results. Based on this analysis, we derived a set of energy-dependent correction factors of the observed responses, enabling a statistically robust analysis of the whole spectral dataset. They will be employed in subsequent papers describing the astrophysical results of the campaign.

Abstract

Accretion disks in strong gravity ubiquitously produce winds, seen as blueshifted absorption lines in the X-ray band of both stellar mass X-ray binaries (black holes and neutron stars)^1–4 and supermassive black holes⁵. Some of the most powerful winds (termed Eddington winds) are expected to arise from systems in which radiation pressure is sufficient to unbind material from the inner disk (L ≳ L _Edd). These winds should be extremely fast and carry a large amount of kinetic power, which, when associated with supermassive black holes, would make them a prime contender for the feedback mechanism linking the growth of those black holes with their host galaxies⁶. Here we show the XRISM Resolve spectrum of the galactic neutron star X-ray binary, GX 13+1, which reveals one of the densest winds ever seen in absorption lines. This Compton-thick wind significantly attenuates the flux, making it appear faint, although it is intrinsically more luminous than usual (L ≳ L _Edd). However, the wind is extremely slow, more consistent with the predictions of thermal-radiative winds launched by X-ray irradiation of the outer disk than with the expected Eddington wind driven by radiation pressure from the inner disk. This puts new constraints on the origin of winds from bright accretion flows in binaries, but also highlights the very different origin required for the ultrafast (v ~ 0.3c) winds seen in recent Resolve observations of a supermassive black hole at a similarly high Eddington ratio⁷.

Abstract

We report on a detailed spectroscopic study of the gas dynamics and hydrostatic mass bias of the galaxy cluster Abell 2029, utilizing high-resolution observations from XRISM Resolve. Abell 2029, known for its cool core and relaxed X-ray morphology, provides an excellent opportunity to investigate the influence of gas motions beyond the central region. Expanding upon prior studies that revealed low turbulence and bulk motions within the core, our analysis covers regions out to the scale radius $R_{2500}$ (670 kpc) based on three radial pointings extending from the cluster center toward the northern side. We obtain accurate measurements of bulk and turbulent velocities along the line of sight. The results indicate that non-thermal pressure accounts for no more than 2% of the total pressure at all radii, with a gradual decrease outward. The observed radial trend differs from many numerical simulations, which often predict an increase in non-thermal pressure fraction at larger radii. These findings suggest that deviations from hydrostatic equilibrium are small, leading to a hydrostatic mass bias of around 2% across the observed area.

Abstract

We present an analysis of high-resolution spectra from the shock-heated plasmas in SN 1987A, based on an observation using the Resolve instrument onboard the X-Ray Imaging and Spectroscopy Mission (XRISM). The 1.7–10 keV Resolve spectra are accurately represented by a single-component, plane-parallel shock plasma model, with a temperature of $2.84_{-0.08}^{+0.09}$ keV and an ionization parameter of $2.64_{-0.45}^{+0.58}$ × $10^{11}\,\,{\rm s\,\, cm}^{-3}$. The Resolve spectra are also well reproduced by the 3D magneto-hydrodynamic simulation presented by Orlando et al. (2020, A&A, 636, A22) suggesting substantial contribution from the ejecta. The metal abundances obtained with Resolve align with the Large Magellanic Cloud value, indicating that the X-rays in 2024 originate from “non-metal-rich” shock-heated ejecta and the reverse shock has not reached the inner metal-rich region of ejecta. Doppler widths of the atomic lines from Si, S, and Fe correspond to velocities of 1500–1700 km s$^{-1}$, where the thermal broadening effects in this non-metal-rich plasma are negligible. Therefore, the line broadening seen in Resolve spectra is determined by the large bulk motion of ejecta. For reference, we determined a $90\%$ upper limit on non-thermal emission from a pulsar wind nebula at $4.3 \times 10^{-13}$ erg cm$^{-2}$ s$^{-1}$ in the 2–10 keV range, aligning with NuSTAR findings by Greco et al. (2022, ApJ, 931, 132). Additionally, we searched for the $^{44}$Sc K line feature and found a $1\sigma$ upper limit of $1.0 \times 10^{-6}$ photons cm$^{-2}$ s$^{-1}$, which translates to an initial $^{44}$Ti mass of approximately $2 \times 10^{-4}\, M_{\odot }$, consistent with previous X-ray to soft gamma-ray observations (Boggs et al. 2015, Science, 348, 670; Grebenev et al. 2012, Nature, 490, 373; Leising 2006, ApJ, 651, 1019).

Abstract

W49B is a unique Galactic supernova remnant with centrally peaked, “bar”-like ejecta distribution, which was once considered evidence for a hypernova origin that resulted in a bipolar ejection of the stellar core. However, chemical abundance measurements contradict this interpretation. Closely connected to the morphology of the ejecta is its velocity distribution, which provides critical details for understanding the explosion mechanism. We report the first ever observational constraint on the kinematics of the ejecta in W49B using the Resolve microcalorimeter spectrometer on the X-ray Imaging and Spectroscopy Mission (XRISM). Using XRISM/Resolve, we measured the line-of-sight velocity traced by the Fe Heα emission, which is the brightest feature in the Resolve spectrum, to vary by ±300 km s⁻¹ with a smooth east-to-west gradient of a few tens of kilometers per second per parsec along the major axis. Similar trends in the line-of-sight velocity structure were found for other Fe-group elements Cr and Mn, traced by the Heα emission, and also for intermediate-mass elements Si, S, Ar, and Ca, traced by the Lyα emission. The discovery of the east–west gradient in the line-of-sight velocity, together with the absence of a twin-peaked line profile or enhanced broadening in the central region, clearly rejects the equatorially expanding disk model. In contrast, the observed velocity structure suggests bipolar flows reminiscent of a bipolar explosion scenario. An alternative scenario would be a collimation of the ejecta by an elongated cavity sculpted by bipolar stellar winds.

Abstract

We report on XRISM/Resolve spectroscopy of the recurrent transient and well-known black hole candidate 4U 1630−472 during its 2024 outburst. The source was captured at the end of a disk-dominated high/soft state at an Eddington fraction of λ _Edd ∼ 0.05 (10 M _⊙/M _BH). A variable absorption spectrum with unprecedented complexity is revealed with the Resolve calorimeter. This marks one of the lowest Eddington fractions at which highly ionized absorption has been detected in an X-ray binary. The strongest lines are fully resolved, with He-like Fe XXV separated into resonance and intercombination components and H-like Fe XXVI seen as a spin–orbit doublet. The depth of some absorption lines varied by almost an order of magnitude, far more than expected based on a 10% variation in apparent X-ray flux and ionization parameter. The velocity of some absorption components also changed significantly. Jointly modeling two flux segments with a consistent model including four photoionization zones, the spectrum can be described in terms of highly ionized but likely failed winds that sometimes show redshifts, variable obscuration that may signal asymmetric structures in the middle and outer accretion disk, and a tentative very fast outflow (v = 0.026–0.033c). We discuss the impact of these findings on our understanding of accretion and winds in stellar-mass black holes and potential consequences for future studies.

Abstract

The Galactic Center region was observed with the X-Ray Imaging and Spectroscopy Mission (XRISM) X-ray observatory during the performance verification phase in 2024 and a point-like X-ray source was detected with the X-ray imager Xtend at a position of $(\alpha , \delta )_{\rm J2000.0}=({17^{\rm h}46^{\rm m}10{_{.}^{\rm s } }8}, {-29^{\circ}00^{\prime }21^{\prime \prime } })$, which is thus named XRISM J174610.8-290021. This source was bright in February to March and showed time variations in count rate by more than one order of magnitude in one week. The 2–10 keV X-ray luminosity was ${\sim }10^{35}$ erg s$^{-1}$ for the assumed distance of 8 kpc. However, after six months, it was below the detection limit. We found a hint of periodicity of 1537 s from timing analysis. The XRISM/Xtend spectrum has emission lines from helium-like iron (Fe xxv–He$\alpha$) at 6.7 keV and hydrogen-like iron (Fe xxvi–Ly$\alpha$) at 6.97 keV; their intensity ratio is unusual with the latter being four times stronger than the former. If the emission is of thermal origin, the ionization temperature estimated from the iron-line intensity ratio is $\sim$30 keV, which is inconsistent with the electron temperature estimated from the thermal bremsstrahlung, $\sim$7 keV. Spectral models of magnetic cataclysmic variables, which are often seen in the Galactic Center in this luminosity range, are found to fail to reproduce the obtained spectrum. By contrast, we found that the spectrum is well reproduced with the models of low-mass X-ray binaries containing a neutron star plus two narrow Gaussian lines. We consider that the source is intrinsically bright reaching $10^{37}$ erg s$^{-1}$, but is blocked from direct view due to a high inclination and only the scattered emission is visible. The photo-ionized plasma above the accretion disk with an ionization parameter of ${\sim }10^{5}$ may explain the unusual iron line ratio. We further discuss the potential contribution of point sources of the type of XRISM J174610.8-290021 to the diffuse Galactic Center X-ray emission.

Abstract

The XRISM Resolve microcalorimeter array measured the velocities of hot intracluster gas at two positions in the Coma galaxy cluster: squares at the center and at 6 (170 kpc) to the south. We find the line-of-sight velocity dispersions in those regions to be σ _z = 208 ± 12 km s⁻¹ and 202 ± 24 km s⁻¹, respectively. The central value corresponds to a 3D Mach number of M = 0.24 ± 0.015 and a ratio of the kinetic pressure of small-scale motions to thermal pressure in the intracluster plasma of only 3.1% ± 0.4%, at the lower end of predictions from cosmological simulations for merging clusters like Coma, and similar to that observed in the cool core of the relaxed cluster A2029. Meanwhile, the gas in both regions exhibits high line-of-sight velocity differences from the mean velocity of the cluster galaxies, Δv _z = 450 ± 15 km s⁻¹ and 730 ± 30 km s⁻¹, respectively. A small contribution from an additional gas velocity component, consistent with the cluster optical mean, is detected along a sight line near the cluster center. The combination of the observed velocity dispersions and bulk velocities is not described by a Kolmogorov velocity power spectrum of steady-state turbulence; instead, the data imply a much steeper effective slope (i.e., relatively more power at larger linear scales). This may indicate either a very large dissipation scale, resulting in the suppression of small-scale motions, or a transient dynamic state of the cluster, where large-scale gas flows generated by an ongoing merger have not yet cascaded down to small scales.

Abstract

We present XRISM Resolve observations of the core of the hot, relaxed galaxy cluster Abell 2029 (A2029). We find that the line-of-sight bulk velocity of the intracluster medium (ICM) within the central 180 kpc is at rest with respect to the brightest cluster galaxy, with a 3σ upper limit of ∣v _bulk∣ < 100 km s⁻¹. We robustly measure the field-integrated ICM velocity dispersion to be σ _v = 169 ± 10 km s⁻¹, obtaining similar results for both single-temperature and two-temperature plasma models to account for the cluster cool core. This result, if ascribed to isotropic turbulence, implies a subsonic ICM with Mach number and a nonthermal pressure fraction of 2.6 ± 0.3%. The turbulent velocity is similar to what was measured in the core of the Perseus cluster by Hitomi, but here in a more massive cluster with an ICM temperature of 7 keV, the limit on the nonthermal pressure fraction is even more stringent. Our result is consistent with expectations from simulations of relaxed clusters, but it is on the low end of the predicted distribution, indicating that A2029 is an exceptionally relaxed cluster with no significant impacts from either a recent minor merger or active galactic nucleus activity.

Abstract

Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, Sagittarius A$^{*}$. The X-ray emission of the remnant is suspected to show features of overionized plasma, which would require peculiar evolutionary paths. We report on the first observation of Sagittarius A East with the X-Ray Imaging and Spectroscopy Mission (XRISM). Equipped with a combination of a high-resolution microcalorimeter spectrometer and a large field-of-view CCD imager, we for the first time resolved the Fe xxv K-shell lines into fine structure lines and measured the forbidden-to-resonance intensity ratio to be $1.39 \pm 0.12$, which strongly suggests the presence of overionized plasma. We obtained a reliable constraint on the ionization temperature just before the transition into the overionization state, of $\gt\! 4\:$keV. The recombination timescale was constrained to be $\lt\! 8 \times 10^{11} \:$cm$^{-3}\:$s. The small velocity dispersion of $109 \pm 6\:$km$\:$s$^{-1}$ indicates a low Fe ion temperature $\lt\! 8\:$keV and a small expansion velocity $\lt\! 200\:$km$\:$s$^{-1}$. The high initial ionization temperature and small recombination timescale suggest that either rapid cooling of the plasma via adiabatic expansion from dense circumstellar material or intense photoionization by Sagittarius A$^{*}$ in the past may have triggered the overionization.

Abstract

The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes the dynamics of the photoionized gas in the system. In this Letter, we report on an observation of Cyg X-3 with the XRISM/Resolve spectrometer, which provides unprecedented spectral resolution and sensitivity in the 2–10 keV band. We detect multiple kinematic and ionization components in absorption and emission whose superposition leads to complex line profiles, including strong P Cygni profiles on resonance lines. The prominent Fe xxv Heα and Fe xxvi Lyα emission complexes are clearly resolved into their characteristic fine-structure transitions. Self-consistent photoionization modeling allows us to disentangle the absorption and emission components and measure the Doppler velocity of these components as a function of binary orbital phase. We find a significantly higher velocity amplitude for the emission lines than for the absorption lines. The absorption lines generally appear blueshifted by ∼−500–600 km s⁻¹. We show that the wind decomposes naturally into a relatively smooth and large-scale component, perhaps associated with the background wind itself, plus a turbulent, denser structure located close to the compact object in its orbit.

Abstract

We present an initial analysis of the X-Ray Imaging and Spectroscopy Mission (XRISM) first-light observation of the supernova remnant (SNR) N 132D in the Large Magellanic Cloud. The Resolve microcalorimeter has obtained the first high-resolution spectrum in the 1.6–10 keV band, which contains K-shell emission lines of Si, S, Ar, Ca, and Fe. We find that the Si and S lines are relatively narrow, with a broadening represented by a Gaussian-like velocity dispersion of $\sigma _v \sim 450$ km s$^{-1}$. However, the Fe He$\alpha$ lines are substantially broadened with $\sigma _v \sim 1670$ km s$^{-1}$. This broadening can be explained by a combination of the thermal Doppler effect due to the high ion temperature and the kinematic Doppler effect due to the SNR expansion. Assuming that the Fe He$\alpha$ emission originates predominantly from the supernova ejecta, we estimate the reverse shock velocity at the time when the bulk of the Fe ejecta were shock heated to be $-1000 \lesssim V_{\rm rs}$ (km s$^{-1}$) $\lesssim 3300$ (in the observer frame). We also find that Fe Ly$\alpha$ emission is redshifted with a bulk velocity of $\sim 890$ km s$^{-1}$, substantially larger than the radial velocity of the local interstellar medium surrounding N 132D. These results demonstrate that high-resolution X-ray spectroscopy is capable of providing constraints on the evolutionary stage, geometry, and velocity distribution of SNRs.

Abstract

We present an analysis of the first two XRISM/Resolve spectra of the well-known Seyfert-1.5 active galactic nucleus (AGN) in NGC 4151, obtained in 2023 December. Our work focuses on the nature of the narrow Fe K_α emission line at 6.4 keV, the strongest and most common X-ray line observed in AGN. The total line is found to consist of three components. Even the narrowest component of the line is resolved with evident Fe K_α,1 (6.404 keV) and K_α,2 (6.391 keV) contributions in a 2:1 flux ratio, fully consistent with neutral gas with negligible bulk velocity. Subject to the limitations of our models, the narrowest and intermediate-width components are consistent with emission from optically thin gas, suggesting that they arise in a disk atmosphere and/or wind. Modeling the three line components in terms of Keplerian broadening, they are readily associated with (1) the inner wall of the “torus,” (2) the innermost optical “broad-line region” (or “X-ray BLR”), and (3) a region with a radius of r ≃ 100 GM/c ² that may signal a warp in the accretion disk. Viable alternative explanations of the broadest component include a fast-wind component and/or scattering; however, we find evidence of variability in the narrow Fe K_α line complex on timescales consistent with small radii. The best-fit models are statistically superior to simple Voigt functions, but when fit with Voigt profiles the time-averaged lines are consistent with a projected velocity broadening of FWHM . Overall, the resolution and sensitivity of XRISM show that the narrow Fe K line in AGN is an effective probe of all key parts of the accretion flow, as it is currently understood. We discuss the implications of these findings for our understanding of AGN accretion, future studies with XRISM, and X-ray-based black hole mass measurements.

Abstract

LiteBIRD the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and fundamental physics. The Japan Aerospace Exploration Agency (JAXA) selected LiteBIRD in May 2019 as a strategic large-class (L-class) mission, with an expected launch in the late 2020s using JAXA’s H3 rocket. LiteBIRD is planned to orbit the Sun-Earth Lagrangian point L2, where it will map the cosmic microwave background (CMB) polarization over the entire sky for three years, with three telescopes in 15 frequency bands between 34 and 448 GHz, to achieve an unprecedented total sensitivity of 2.2 μK-arcmin, with a typical angular resolution of 0.5○ at 100 GHz. The primary scientific objective of LiteBIRD is to search for the signal from cosmic inflation, either making a discovery or ruling out well-motivated inflationary models. The measurements of LiteBIRD will also provide us with insight into the quantum nature of gravity and other new physics beyond the standard models of particle physics and cosmology. We provide an overview of the LiteBIRD project, including scientific objectives, mission and system requirements, operation concept, spacecraft and payload module design, expected scientific outcomes, potential design extensions and synergies with other projects. Subject Index LiteBIRD cosmic inflation, cosmic microwave background, B-mode polarization, primordial gravitational waves, quantum gravity, space telescope

Abstract

2S 0921−630 is an eclipsing low-mass X-ray binary (LMXB) with an orbital period of ∼9 d. Past X-ray observations have revealed that 2S 0921−630 has an extended accretion disk corona (ADC), from which most of the X-rays from the system are emitted. We report the result of our Suzaku archival data analysis of 2S 0921−630. The average X-ray spectrum is reproduced with a blackbody emission (kTbb ∼ 0.3 keV) Comptonized by optically thick gas (“Compton cloud”; optical depth τ ∼ 21) with a temperature of ∼2 keV, combined with 13 emission lines. We find that most of the emission lines correspond to highly ionized atoms: O, Ne, Mg, Si, S, Ar, and Fe. A Kα emission line and an absorption edge of semi-neutral iron (Fe textsci– textscxvii) are also detected. The semi-neutral iron Kα line is significantly broad, with a width of 0.11 ± 0.02 keV in sigma, which corresponds to the Doppler broadening by the Kepler motion at a radius of ∼109 cm. We suggest that the observed semi-neutral iron line originates at the inner part of the accretion disk in the immediate outside of the Compton cloud, i.e., the Compton cloud may have a radius of ∼109 cm.

<title>Abstract</title>
Pulse-phase-resolved X-ray spectra of the X-ray pulsar Her X-1 observed with Suzaku are analyzed. The analysis is based on a hypothesis that the observed variations of the continuum spectra associated with the neutron star spin originate in the changes of the projection areas of the emission regions viewed from the observer, and that the spectral shape observed from each of the emission regions does not change with the viewing angle variation. We calculate the ratios of the fluxes in each energy bin between arbitrary pairs of the pulse-phase-resolved spectra over the entire energy range. We identify flat portions in these ratio spectra, which are likely to indicate the intrinsic emission components that have invariant spectral shapes, in the three energy bands of below ∼1 keV, 2–6 keV, and above ∼18 keV. Then, we approximately solve the simultaneous equations for the intrinsic spectral components from a pair of the phase-resolved spectra that show flat portions in the ratio spectrum. As a result, spectra of the three components are obtained as the low-, medium-, and high-energy bands corresponding to those for the flat portions. They are found to be well fitted with a soft blackbody, a cut-off power law, and a hard blackbody model, respectively. Finally, we fit all the phase-resolved spectra simultaneously with a composite model of three continuum components together with a cyclotron absorption feature and an iron line, and obtain an acceptable result. The origins of the cut-off power-law and hard blackbody components are discussed in relation to recently developed theoretical models.

The origin of the narrow Fe-K{\alpha} fluorescence line at 6.4 keV from 
active galactic nuclei has long been under debate; some of the possible sites 
are the outer accretion disk, the broad line region, a molecular torus, or 
interstellar/intracluster media. In February-March 2016, we performed the first 
X-ray microcalorimeter spectroscopy with the Soft X-ray Spectrometer (SXS) 
onboard the Hitomi satellite of the Fanaroff-Riley type I radio galaxy NGC 1275 
at the center of the Perseus cluster of galaxies. With the high energy 
resolution of ~5 eV at 6 keV achieved by Hitomi/SXS, we detected the 
Fe-K{\alpha} line with ~5.4 {\sigma} significance. The velocity width is 
constrained to be 500-1600 km s$^{-1}$ (FWHM for Gaussian models) at 90% 
confidence. The SXS also constrains the continuum level from the NGC 1275 
nucleus up to ~20 keV, giving an equivalent width ~20 eV of the 6.4 keV line. 
Because the velocity width is narrower than that of broad H{\alpha} line of 
~2750 km s$^{-1}$, we can exclude a large contribution to the line flux from 
the accretion disk and the broad line region. Furthermore, we performed pixel 
map analyses on the Hitomi/SXS data and image analyses on the Chandra archival 
data, and revealed that the Fe-K{\alpha} line comes from a region within ~1.6 
kpc from the NGC 1275 core, where an active galactic nucleus emission 
dominates, rather than that from intracluster media. Therefore, we suggest that 
the source of the Fe-K{\alpha} line from NGC 1275 is likely a low-covering 
fraction molecular torus or a rotating molecular disk which probably extends 
from a pc to hundreds pc scale in the active galactic nucleus system.

We present results from the Hitomi X-ray observation of a young 
composite-type supernova remnant (SNR) G21.5$-$0.9, whose emission is dominated 
by the pulsar wind nebula (PWN) contribution. The X-ray spectra in the 0.8-80 
keV range obtained with the Soft X-ray Spectrometer (SXS), Soft X-ray Imager 
(SXI) and Hard X-ray Imager (HXI) show a significant break in the continuum as 
previously found with the NuSTAR observation. After taking into account all 
known emissions from the SNR other than the PWN itself, we find that the Hitomi 
spectra can be fitted with a broken power law with photon indices of 
$\Gamma_1=1.74\pm0.02$ and $\Gamma_2=2.14\pm0.01$ below and above the break at 
$7.1\pm0.3$ keV, which is significantly lower than the NuSTAR result ($\sim9.0$ 
keV). The spectral break cannot be reproduced by time-dependent particle 
injection one-zone spectral energy distribution models, which strongly 
indicates that a more complex emission model is needed, as suggested by recent 
theoretical models. We also search for narrow emission or absorption lines with 
the SXS, and perform a timing analysis of PSR J1833$-$1034 with the HXI and 
SGD. No significant pulsation is found from the pulsar. However, unexpectedly, 
narrow absorption line features are detected in the SXS data at 4.2345 keV and 
9.296 keV with a significance of 3.65 $\sigma$. While the origin of these 
features is not understood, their mere detection opens up a new field of 
research and was only possible with the high resolution, sensitivity and 
ability to measure extended sources provided by an X-ray microcalorimeter.

The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido JapanWe have developed the X-ray CCD camera system for the Soft X-ray Imager (SXI) which will be launched as focal plane detectors of X-ray telescope onboard the Japanese 6th X-ray astronomical satellite, Astro-H. The X-ray CCD is back-illuminated (BI) CCD which has an Optical Blocking Layer (OBL) directly coating its X-ray illumination surface with Aluminum-Polyimide-Aluminum instead of Optical Blocking Filter (OBF). The X-ray CCD is affected by large doses of extreme ultraviolet (EUV) radiation from Earth sun-lit atmosphere (airglow) in orbit. To evaluate the performance of polyimide that cut off EUV, we measured the EUV transmission of both OBL and OBF at various energy range between 15 - 72 eV by utilizing beam line located at the Photon Factory in High Energy Accelerator Research Organization (KEK-PF) in this March and June, and obtained the EUV transmission to be 3% at 41 eV which is as same as expected transmission from the designed thickness of polyimide layer.Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of ScienceNumber of authors: 22

The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido JapanSXI (Soft X-ray Imager) is the X-ray CCD camera system consisting of 4 back-illuminated CCD chips of 1280 x 1280 - pixel format, each of which is read out with 2 x 2 on-chip binning scheme at every 4 sec, and a couple of single stage Stirling coolers. The incident optical photons are blocked by OBL (optical blocking layer) coated on the chips instead of traditional optical blocking filters. The contamination on OBL from the spacecraft is controlled by a baffle connecting the camera body and the X-ray telescope mirror. The CCD driver and ADC are placed in the camera body unit, and no analog signal appears among the SXI components. All the analog and digital BBMs have already been built, while some functions in the digital part have not implemented yet and the end-to-end analog performance has not investigated yet.Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of ScienceNumber of authors: 22

IS THE BLACK HOLE IN GX 339-4 REALLY SPINNING RAPIDLY? Reviewed

Publishing type：Research paper (scientific journal) Publisher：IOP PUBLISHING LTD

The wide-band Suzaku spectra of the black hole (BH) binary GX 339-4, acquired in 2007 February during the Very High state, were reanalyzed. Effects of event pileup (significant within similar to 3' of the image center) and telemetry saturation of the X-ray Imaging Spectrometer (XIS) data were carefully considered. The source was detected up to similar to 300 keV, with an unabsorbed 0.5-200 keV luminosity of 3.8 x 10(38) erg s(-1) at 8 kpc. The spectrum can be approximated by a power law of photon index 2.7, with a mild soft excess and a hard X-ray hump. When using the XIS data outside 2' of the image center, the Fe K line appeared extremely broad, suggesting a high BH spin as already reported by Miller et al. based on the same Suzaku data and other CCD data. When the XIS data accumulation is further limited to > 3' to avoid event pileup, the Fe K profile becomes narrower, and a marginally better solution appears which suggests that the inner disk radius is 5-14 times the gravitational radius (1 sigma), though a maximally spinning BH is still allowed by the data at the 90% confidence level. Consistently, the optically thick accretion disk is inferred to be truncated at a radius 5-32

Orbital calibrations of the XIS, in terms of the energy scale, energy resolution, and quantum efficiency, are needed not only to confirm the calibrations on the ground but also to examine inevitable performance change in orbit. Fundamentals of the XIS calibration issues have been established and are implemented the softwares and the data base for general observers. We overview the current status of the XIS calibration in orbit.

Soft X-ray response of X-ray Imaging Spectrometers (XIS) for the Astro-E satellite is measured with a grating spectrometer system at Osaka. First, relation between incident X-ray energy and output pulse height peak (E-PH relation) is examined with an SX grating. It is found that jump in the E-PH relation around Si-K edge is at most 2.7 eV. Second, quantum efficiency (QE) of the XIS in 0.4-2.2 kev range is measured relatively to the reference CCD of which absolute QE was calibrated with a gas proportional counter. The QE is fitted with a model in which CCD gate structures are considered. Systematic error on the QE results is estimated by referring an independent measurement. Third, tuning and improvement of the response function is performed. We employ six components to reproduce the response profile of the XIS. In this paper, improvement of one component which is originated in the events absorbed in the channel-stop is presented. Neverthless, Astro-E was lost due to the launch failure. We overview the XIS project in its flight model phase, modified points of the design, problems and solutions etc., in order to be utilized in a possible recovery of the satellite.

The Crab nebula originated from a core-collapse supernova (SN) explosion 
observed in 1054 A.D. When viewed as a supernova remnant (SNR), it has an 
anomalously low observed ejecta mass and kinetic energy for an Fe-core collapse 
SN. Intensive searches were made for a massive shell that solves this 
discrepancy, but none has been detected. An alternative idea is that the SN1054 
is an electron-capture (EC) explosion with a lower explosion energy by an order 
of magnitude than Fe-core collapse SNe. In the X-rays, imaging searches were 
performed for the plasma emission from the shell in the Crab outskirts to set a 
stringent upper limit to the X-ray emitting mass. However, the extreme 
brightness of the source hampers access to its vicinity. We thus employed 
spectroscopic technique using the X-ray micro-calorimeter onboard the Hitomi 
satellite. By exploiting its superb energy resolution, we set an upper limit 
for emission or absorption features from yet undetected thermal plasma in the 
2-12 keV range. We also re-evaluated the existing Chandra and XMM-Newton data. 
By assembling these results, a new upper limit was obtained for the X-ray 
plasma mass of <~ 1Mo for a wide range of assumed shell radius, size, and 
plasma temperature both in and out of the collisional equilibrium. To compare 
with the observation, we further performed hydrodynamic simulations of the Crab 
SNR for two SN models (Fe-core versus EC) under two SN environments (uniform 
ISM versus progenitor wind). We found that the observed mass limit can be 
compatible with both SN models if the SN environment has a low density of <~ 
0.03 cm-3 (Fe core) or <~ 0.1 cm-3 (EC) for the uniform density, or a 
progenitor wind density somewhat less than that provided by a mass loss rate of

The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido JapanWe report the XIS calibration on the data taken with the 2 x 2 mode and window option and the current status of the XIS Non-X-ray Background (NXB) database. The 2 x 2 mode and window option are useful for bright source observations to avoid telemetry saturation and event pile-up. The NXB database provides the best-estimated NXB spectrum for any specific observations obtained with the standard mode (Normal-Clock with no Window or Burst and 5 x 5(sub -) (3 x 3(sub -) Editing mode). The data taken with the 2 x 2 mode in the "SCI-off" era are fully calibrated, and there is no practical difference from those taken with the standard mode. A calibration study for the data taken with the 2 x 2 mode in the "SCI-on" era is on-going. The calibration for the data taken with the window option was significantly improved in the HEASOFT 6.6.2 released at 2009 April 1st. In the comparison with the standard-mode data, the gain difference around 6 keV becomes less than 10 and 15 eV in XIS 0,3 and XIS 1, respectively. We have been updating the NXB database every half a year. There is no drastic change in the light curves, but steady approximately 4 % year(sup -1) level increase and decrease are found in those of XIS 0,3 and XIS 1, respectively.Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of ScienceNumber of authors: 25

Reproducibility of Non-X-ray Background for the X-ray Imaging Spectrometer aboard Suzaku

One of the advantages of the X-ray Imaging Spectrometer (XIS) system on board 
Suzaku is its low and stable non-X-ray background (NXB). In order to make the 
best use of this advantage, modeling the NXB spectra with high accuracy is 
important to subtract them from the spectra of on-source observations. We 
construct an NXB database by collecting XIS events when the dark Earth covers 
the XIS FOV. The total exposure time of the NXB data is about 785 ks for each 
XIS. It is found that the count rate of the NXB anti-correlates with the 
cut-off-rigidity and correlates with the count rate of the PIN upper 
discriminator (PIN-UD) in Hard X-ray Detector on board Suzaku. We thus model 
the NXB spectrum for a given on-source observation by employing either of these 
parameters and obtain a better reproducibility of the NXB for the model with 
PIN-UD than that with the cut-off-rigidity. The reproducibility of the NXB 
model with PIN-UD is 4.55-5.63% for each XIS NXB in the 1-7 keV band and 
2.79-4.36% for each XIS NXB in the 5-12 keV band for each 5 ks exposure of the 
NXB data. This NXB reproducibility is much smaller than the spatial fluctuation 
of the cosmic X-ray background in the 1-7 keV band, and is almost comparable to 
that in the 5-12 keV band.

(Fabbiano 1988b; Kohmura et al. 1994; Uno 1997), IC 342 Source 1 (Okada et al. 
1998), Dwingeloo 1 X-1 (Reynolds et al. 1997), NGC 1313 Source B (Fabbiano & 
Trinchieri 1987; Petre et al. 1994), and two sources in NGC 4565 (Mizuno et al. 
1999). With the 0.5--10 keV luminosities in the range 10^{39-40} ergs/s, they 
are thought to represent a class of enigmatic X-ray sources often found in 
spiral galaxies. For some of them, the ASCA data are newly processed, or the 
published spectra are reanalyzed. For others, the published results are quoted. 
The ASCA spectra of all these seven sources have been described successfully 
with so called multi-color disk blackbody (MCD) emission arising from 
optically-thick standard accretion disks around black holes. Except the case of 
M33 X-8, the spectra do not exhibit hard tails. For the source luminosities not 
to exceed the Eddington limits, the black holes are inferred to have rather 
high masses, up to ~100 solar masses. However, the observed innermost disk 
temperatures of these objects, Tin = 1.1--1.8 keV, are too high to be 
compatible with the required high black-hole masses, as long as the standard 
accretion disks around Schwarzschild black holes are assumed. Similarly high 
disk temperatures are also observed from two Galactic transients with 
superluminal motions, GRO 1655-40 and GRS 1915+105. The issue of unusually high 
disk temperature may be explained by the black hole rotation, which makes the 
disk get closer to the black hole, and hence hotter.

An eclipsing X-ray binary pulsar, Centaurus X-3 was observed with the ASCA satellite on Februarly 1-2 1995,during a non-eclipse phase of 0.11 to 0.81. We found that the X-ray pulse profiles observed with ASCA change in shape and amplitude according with the orbital phase. The three K_α lines at 6.4,6.67,and 6.96 keV from neutral, He-like, and H-like ironions, respectively, could be resolved in the observed energy spectrum owing to the high energy resolution of the CCD cameras on board ASCA. We found that the intensity of the 6.4 keV line changes with pulse phase. Distribution and ionization degree of matter surrounding the neutron star are discussed based on this result.

In order to constrain the radius of neutron stars by using the ASTRO-H (Hitomi) satellite, we performed necessary improvements and tests for X-ray detectors onboard ASTRO-H. We succeeded in demonstrating the required performances, such as the energy resolution of 4.9 eV by Micro Calorimeter. We improved high counting capability of the data acquisition system, required for neutron star observations. Despite of the early termination of the satellite, we have succeeded in obtaining technology to measure the radius of neutron stars, precisely. This enables us to constrain the EOS of nuclear matter by future missions.
By using archival data, we detected characteristic structure in a spectrum during an X-ray burst and proposed a new method to estimate the gravitational redshift at the neutron star surface. We advanced development of new detectors for future X-ray and gamma-ray missions, such as a semiconductor sensor for high counting observation and a detector to measure X-ray polarization.

A research to exclude charged-particle events from X-ray CCD detector output was carried out. Two full-depletion CCD of 200um thickness are stacked with 125 um gap, and events on a chip that have counterparts in a few pixel distance on the other chip are regarded as of charged-particle origin. The chips are mounted on the both sides of a ceramic board with a central hole. We tested the charged-particle descrimination with 230 MeV proton beam, and confirmed that significant part of the events are recognized as the charged-particle origin. The recognition efficiency is, however, significantly lower than our Monte Carlo simulation prediction. Thus further study about the detail of the incident particles and development of the optimal chip alignment and signal processing scheme are required for a practical use.

X-ray CCDs are now regarded as a standard focal plane detector of X-ray telescopes. Among them, backside illuminated CCDs with a deep depletion layer are being most widely used. However, because the electric field is weak at the back surface and the charge clouds tend to extend largely, they have poorer energy resolution and higher charged-particle background. Thus, we tried to suppress the charge extension by applying an external magnetic field and to improve the CCD's performance. We found that only a magnetic field of 0.3T is enough to cause systematic difference in charge splitting along the horizontal direction. Furthermore, although significance was low, we found energy resolution to improve slightly with the magnetic field. These results show for the first time that we can control the movement of charges in silicon and improve the performance of X-ray CCDs by applying an external magnetic field.

X線天文衛星『すざく』のデータを用いて、突発型X線パルサーA0535+262および超強磁石星CXOUJ164710.2-455216の解析を行った。
A0535+262は、突発的に明るくなり数ケ月かけて減光していくX線連星パルサーで、『すざく』はその減光時に観測を行った。観測されるエネルギースペクトルが、中性子星の自転周期(103秒)に同期してどのように変化するか調べたどころ、鉄からの輝線および軟X線放射成分が自転に同期して強度変動している事が明らかになった。これは、降着円盤が凹な構造をしており、その外側が中性子星からのX線照射を受けている証拠と考えられる。突発型のX線連星の減光時には、降着円盤には伴星からの質量流入はあまりないと考えられ、そのような状況下でも降着円盤が凹な構造をしていることを明らかにすることができた。
一方、CXOUJ164710.2-455216は、非常に強い表面磁場(10^<14>ガウス程度)を持つと考えられる中性子星で、磁気エネルギーが元になってX線やガンマ線放射が起きていると考えられている。2006年9月のアウトバースト直後を『すざく』で観測したところ、軟X線領域では3つのピークを持つパルス波形をしていたのに対し、硬X線領域ではひと山の波形になっていることがわかった。アウトバースト前はひと山の波形だったので、アウトバーストに伴い、軟X線領域で新たな輻射領域が現れたと考えられる。3つのピークを持つ輻射成分のエネルギースペクトルは黒体放射をしていることから、アウトバーストに伴い磁場の再編が起こり、新たに出現した3つの磁極から黒体放射が出て、観測されたような三山の波形ができていると考えられる。

Astro-E2衛星は、2005年1-2月期の打ち上げを目指し、現在製作が鋭意進められている。Astro-E2に搭載される主な観測装置は日米の研究者による国際協力によって開発されてきている。また、目指すべき観測的成果、それに応じた観測装置や衛星設計の最適化については、日米の観測装置開発チームに、日米欧の高エネルギー宇宙物理研究者10名ほどをアドバイザーとして加え、100人ほどのAstro-E2科学作業委員会を結成して議論してきている。
Astro-E2衛星は、軌道に投入され本格的観測運用が可能になった暁には、国際的X線軌道天文台として、世界の研究者の利用に供せられることとなるが、そのような公募観測が順調に始められるためには、観測装置の科学的性能が十分把握されている必要があり、打上げ後半年ほどは、観測装置の性能評価や科学的性能の評価のための試験観測が行われる。今年度、本研究費の補助により、試験観測期間観測プログラム作成の作業として、観測プログラム中の具体的観測目的の科学的評価に係る部分と、観測装置の性能評価に係る部分の作業が行われた。観測目的の科学的評価については、ISASにおいて2003年11月11-13日と2004年3月17-19日の2度、科学作業委員会が開かれた。そこにおいては、観測対象によりわけた5つのサブグループを作って、それぞれの観測ターゲット・観測目的の洗い出しを行い、科学的目的の重要度のランク付けを行うとともに、それぞれの目的に最適な対象天体の選別を行った。本研究費からは、ヨーロッパからのアドバイザーに旅費補助がなされた。一方、観測装置の性能評価については、日米欧で行われた打ち合わせに、日本側研究者が参加する旅費補助を行った。作業は順調に行われ、本研究費はたいへん有益であった。

We have studied methods to improve the spatial resolution of the X-ray CCD detector as a spectrometer. The spatial resolution of X-ray CCD is determined mainly by (1) pixel size of the CCD, (2) noise of the measured pulse heights, and (3) data processing algorithm. Among these, we concentrated on items (2) and (3), because the development of CCD with small pixels is beyond the scope of current research.
Both the clock signals and the analogue electronics are keys to reduce the noise of the pulse heights. We adjusted the phase of the clock signals and the sampling timing to minimize the interference of the clocking noise to the output. We developed a low-noise preamplifier and an active low-pass filter to improve the signal-to-noise ratio of the analogue circuits. With these modifications, we could reduce the measurement noise significantly. We also studied the best algorithm to determine the incident position of X-ray photons from the distribution of measured charges. We found that just a simple model fitting with a 2-dimensional Gauss function gives a good result.
We could determine the incident position of X-ray photons with an accuracy of about 20% of the pixsel size. We estimate that the position error can be reduced to 10% with further improvement of S/N ratio. CCDs with pixel size smaller the 10 μm are now available for X-ray detection. With these CCDs it is possible to achieve a spatial resolution less than 1 μm. This is the goal of our research.

科学衛星『あすか』のデータを用い、宇宙環境での電荷結合素子(CCD)の放射線損傷について調べた。『あすか』衛生には、X線天体を観測する目的で、X線反射鏡とその焦点面にX線検出用CCDが搭載されている。このX線CCDは、空乏層厚が約30ミクロンの3相フルフレームトランスファ型CCDで、動作温度は-60℃である。『あすか』衛星は、高度500kmの円軌道を飛行しており、主に放射線帯の高エネルギー陽子により放射線損傷を受けるものと考えられる。解析の結果、放射線損傷の影響は、電荷転送効率の低下と暗電流の増加をもたらしていることがわかった。電荷転送効率は、ほぼ打ち上げ後の経過時間に比例して、約10E-5/transfer/yearの割合で低下している。『あすか』搭載CCDの場合、18.5、37、8700μ秒の3種類の異なる周期のクロックを用いているが、クロック周期が゛2桁違っても転送効率の低下量は数倍しか異ならなかった。これから、転送効率低下の原因となっている電荷トラップは、特定のエネルギーレベルにできるのではなく、かなり広いエネルギーレベルに渡って形成されることが明らかになった。また、電荷転送効率は、転送列ごとに2倍以上変化しており、電荷トラップは著しく不均一に形成されることが明らかになった。一方、暗電流はチップ全体で平均するとやはり打ち上げ後の経過時間に比例して増加しているものの、ピクセル毎のバラツキが大きく、ピクセル単位で調べると、暗電流は数ヶ月に1回、放射線帯通過時に不連続に増加していることが明らかになった。結果として、ピクセル毎の暗電流のばらつきが徐々に増加している。放射線損傷のこのように著しい不均一性は、今回の解析で初めて明らかになった結果であり、宇宙環境でのCCDの応用に役立つものと期待される。

ASCA (ASTRO-D), the fourth X-ray astonomy satellite of ISAS,Japan, was launched in February, 1993. ASCA is an X-ray astronomy observatory which is, for the first time, capable of performing imaging and spectroscopic observations simultaneously over a wide energy range 0.5-10 keV.Whereas, ROSAT,the X-ray astronomy satellite of the Max-Planck Institute, Germany, was launched in June, 1990. ROSAT is also an X-ray astronomy observatory which is characterized by its excellent imaging capability, although it is limited to narrower energy bands than ASCA.ASCA has much higher spectral capability than ROSAT,while ROSAT has much finer imaging capability and higher source detection sensitivity that ASCA.Both observatories are really complimetary to each other.
An extensive collaboration between Japanese and German scientists has been carried out in performing simultaneous observations, cross-calibrations of the X-ray telescopes, exchanging the data, developping analysis software, discussing the scientific yields, presenting the results to international communities, future development of instruments and so on.
The ASCA instruments cover the most important energy band for plasma diagnostics, because all the K-lines and the K-absorption edges from oxygen through iron at various ionization stages lie within this band. The CCD camera of ASCA can resolve all major lines individually. Motion of plasma of the order or greater than 1000 km/s can be measured significantly from Doppler shift of the line energies. These capabilities of ASCA allow diagnostics of accreting matter around such compact objeots as neutron stars and black holes. On the other hand, the ROSAT telescope provides an accurate position of each X-ray sources and enables us to indentify the X-ray sources with optically known sources. The highly resolved spatial information with ROSAT also provides powerful means for the investigations of extended plasmas in supernova remnants, galaxies, and clusters of galaxies. Combining these characteristics of the two observatories, several remarkable scientific results have already been obtained and shown in many scientific papers. This collaborative study should be kept continuing in future.

本研究では、X線CCDの放射線ダメ-ジによる特性変化を調べるため、『あすか』衛星に搭載されているX線CCDのデータをもとに、その長期にわたる特性変化について研究した。まず、超新星残骸の観測データ等、輝線放射の強い天体についてデータベースを作成し、その解析から放射線ダメ-ジの影響が電荷転送効率に現れることを確認した。一方、CCDの暗電流がかなりの割合で増大していることが明らかになり、そのピクセル間のばらつきがエネルギー分解能に著しい劣化をもたらしていることが新たに明らかになった。そこで『あすか』の全データを系統的に処理し、打ち上げから約1年半をカバーするデータベースを作成し、電荷転送効率と暗電流について系統的な調査を行った。その結果、電荷転送効率の低下量そのものは、地上実験からの予想とほぼ一致していたものの、電荷転送クロックの速さによらず、どのようなクロックでもほぼ同程度の低下量を示していることが判明した。これは、宇宙環境では様々なエネルギー準位のトラップができていることを意味しており、今回研究で得られた重要な結果のひとつである。一方、暗電流については、特定のピクセルに注目した時、何ヵ月にもわたって安定しているものの、放射線帯通過後などに不連続に増加しており、この散発的に起こる不連続な増加が全体的な暗電流増加をもたらしていることが明らかになった。この暗電流の増加は各ピクセルごとに独立して進行するため、ピクセル間の暗電流のばらつきが徐々に増大していく。これが、『あすか』搭載のX線CCDカメラの場合、著しいエネルギー分解能の劣化をもたらしている。この点も今回の研究で初めて明らかになった成果である。これらの結果をもとに、次期X線天文衛星搭載のCCDカメラでは、ピクセルごとの暗電流値を衛星上でモニターし、自動補正できるようにする予定である。

The Japan's fourth X-ray astronomy satellite, Astro-D was successfully launched on Feb. 20, 1993, and was named ASCA. The key elements of ASCA were successively turned on in orbit and it started its observatory work since April, 1993. The performance verification observations were done from April to October and not only the performance of the scientific instruments but also the scientific capability wes verified. After then, the guest observations based on proposals by astronomers in the world started.
ASCA is the first X-ray astronomy satellite capable of imaging the X-ray sky in the wide energy range over 0.5 to 12 keV, although the image size of the X-ray telescope is approximately 1 arcminutes FWHM. The sensitivity of ASCA is much better than that of non-imaging instruments such as the large area counters on board Ginga. Furthermore, the CCD camera was carried into orbit for the first time by ASCA and has an outstanding spectral resolution. On the other hand, the German X-ray astronomy satellite ROSAT which has been in orbit for about four years has much better imaging capability and higher sensitivity in the energy range below 0.5 keV than ASCA. ASCA and ROSAT are complementary to each other and several simultaneous observations were already performed both in the performance verification period and the guest observation period. The results of the all sky survey done by ROSAT have also been useful to several ASCA pointing observations. The yields of these collaborations were presented in the international symposium "New Horizon in X-Ray Astronomy-First Rsults from ASCA-" held at the Tokyo Metropolitan University by Institute of Space and Astronautical Science in March, 1994.

The fiscal year of 1991 has become the end of mission life of the Ginga satellite, which stayed in the orbit for 4 years and 9 months since the launch on February 5 1987. The orbit of Ginga continued to decay, until October 30 1991 when the last contact was made with the satellite. It is believed that Ginga re-entered the atmosphere on November 1 or so. Under these circumstances, two scientists from Japan visited the United Kingdom on three occasions, and two UK scientists visited Japan on three occasions as well. Principal results of collaboration in the present fiscal year include the following three items.
(1)The scientists from, both parties closely collaborated on the Ginga operation during the last phase of its mission life. In particular, the Large Area Proportional Counter, a UK-Japan joint experiment serving as the main instrument of Ginga, has been calibrated in detail to demonstrate that its performance stayed constant during the entire mission life.
(2)The entire Ginga data are stored both in Japan and UK, and will continue to be of precious scientific valuable for the entire world. Discussion was therefore made to establish an appropriate scheme to make these archival data open to public, especially to scientists of other countries.
(3)Joint data analysis was made on several research topics, followed by preparations of joint papers. The topics include cosmic X-ray background, active galactic nuclei, X-ray pulsars, X-ray emitting white dwarfs, and so on.
