    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.

    Context. Hot, X-ray emitting atmospheres pervading galaxy clusters (and groups) are rich in metals, which have been synthesised and released by asymptotic giant branch (AGB) stars, core-collapse supernovae (SNcc), and Type Ia supernovae (SNIa) over cosmic history. This makes the intracluster medium (ICM) an ideal astrophysical system to constrain its chemical composition, and hence ultimately understand metal production and enrichment on megaparsec scales.

    Aims. In this work, we take advantage of the unprecedented ∼5 eV resolution offered by the Resolve instrument on board the XRISM observatory to measure the chemical composition of the core of the bright, nearby, and metal-rich Centaurus cluster with unprecedented accuracy. We use these measurements to provide constraints on the stellar populations having enriched the cluster core.

    Methods. Through a deep (287 ks) Resolve full-array spectral analysis of Centaurus, we derived the Fe abundance and its relative Si/Fe, S/Fe, Ar/Fe, Ca/Fe, Cr/Fe, Mn/Fe, and Ni/Fe ratios. We completed this high-resolution view with N/Fe, O/Fe, Ne/Fe, and Mg/Fe ratios obtained with XMM-Newton /RGS archival data. This abundance pattern was then fitted with various combinations of AGBs, SNcc and SNIa nucleosynthesis yields with the aim of constraining their explosion and/or progenitor models.

    Results. Similarly to the core of Perseus (from previous Hitomi /SXS results), we find that nine out of our 11 measured abundance ratios are formally consistent with the chemical composition of our Solar System (within uncertainties of the latter). However, the (super-solar) N/Fe and (half-solar) Mg/Fe ratios significantly differ from Perseus and/or other systems, and thus they provide tension with the picture of a fully solar composition ubiquitous to all systems. In addition, possible uncertainties in O/Fe and Ne/Fe with atomic codes highlight the need for studying more systems at high spectral resolution to assess (or rule out) the universality of the ICM composition in clusters’ cool cores. Combinations of (AGB+)SNcc+SNIa yield models can reproduce our observed X/Fe ratios in all cases. However, whether two distinct populations of SNIa are needed depends on the weight of our RGS measurements. We also briefly discuss the possibility of a multi-metallicity gas phase in this respect.

    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.

    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 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

    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

    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

    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

    The X-Ray Imaging and Spectroscopy Mission (XRISM) is a joint mission between the Japan Aerospace Exploration Agency (JAXA) and the National Aeronautics and Space Administration (NASA) in collaboration with the European Space Agency (ESA). In addition to the three space agencies, universities and research institutes from Japan, North America, and Europe have joined to contribute to developing satellite and onboard instruments, data-processing software, and the scientific observation program. XRISM is the successor to the ASTRO-H (Hitomi) mission, which ended prematurely in 2016. Its primary science goal is to examine astrophysical problems with precise, high-resolution X-ray spectroscopy. XRISM promises to discover new horizons in X-ray astronomy. It carries a 6 × 6 pixelized X-ray microcalorimeter on the focal plane of an X-ray mirror assembly (Resolve) and a co-aligned X-ray CCD camera (Xtend) that covers the same energy band over a large field of view. XRISM utilizes the Hitomi heritage, but all designs were reviewed. The attitude and orbit control system was improved in hardware and software. The spacecraft was launched from the JAXA Tanegashima Space Center on 2023 September 6 (UTC). During the in-orbit commissioning phase, the onboard components were activated. Although the gate valve protecting the Resolve sensor with a thin beryllium X-ray entrance window was not yet opened, scientific observation started in 2024 February with the planned performance verification observation program. The nominal observation program commenced with the following guest observation program beginning in 2024 September.

    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.

    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.

    Cryogenic cooling is useful to most detectors in astronomical and atmospheric observation for improving the sensitivity and reducing the background noise. Recently cryocoolers are often adopted as cooling devices. This paper describes a single stage Stirling cryocooler. It is designed, manufactured and tested for space borne mission. The typical cooling power is 2W at 80K with 50W input. The cooler on the X-ray telescope satellite "Suzaku" was launched July 2005. It is operating over 1 year without any trouble. On the other hand, a cooler achieved 50,000 hour operation in the lifetime test on the ground. Same type coolers will be launched on the lunar explorer and the Venus orbiter of Japan

    3次元電磁場シミュレーションにより,任意の磁気シールド形状において静磁場に対する遮蔽効果を計算できるようになり,シールドの形状,入射窓の径やシールドに対するセンサ位置によって遮蔽効果がどのように変わるか評価を行なった.定性的には穴の大きさと同程度までは磁場が入り込むことで理解できるが,3次元的に定量的に評価できるようになったことは今後に向けて大きな進展である.磁気シールドを強磁性体と超伝導体の2層にした場合の計算も行ない,超伝導体を外にした方が遮蔽効果がよいという結果を得た.強磁性体については磁場に対する透磁率の値を与えることでその特性を正確に取り込むことができるようになったが,超伝導体については現時点では完全導体として扱っており,それが結果にどのように影響しているかは引き続き検討が必要である.中性分子計測実験に向けた相談を実施し,新たに高周波(MHz-GHz)帯域の電磁場の影響の評価も開始した.
    熱解析シミュレーションにより,センサにX線が入射してからパルス信号が得られるまでをモデル化・計算し,測定結果を再現するパルス波形のばらつきを得ることができた.また,クライオスタットの構造を単純化したモデルを構築して,温度0.1 K以下の領域への侵入熱を計算した.まだ自在にモデル化して計算を実施するには至っていないものの,熱計算についても目処が立ちつつある.
    放射光施設でのTESカロリメータを用いた分光分析実験に参加し,実験遂行に貢献した.これにより実際の試験環境を知ることができ,計算を行なう上での参考になった.今後のX線天体の撮像精密分光観測を念頭において,搭載機器の開発や観測的研究も進めた.

    We pursued researches to obtain the best performance from the cutting edge X-ray spectrometer, SXS, and to prepare for its observations. Although the SXS observation was stopped in about a month by malfunction of the ASTRO-H spacecraft, the SXS instrument performed perfectly in orbit. We obtained a scientific result which suggests systematic errors introduced by the macroscopic motion of hot gas is not large in mass determination of cluster of galaxies, which is important for the study of dark energy using clusters We also performed X-ray searches of dark matter. We obtained most stringent constraint on the mixing angle of steel neutrinos in 1 to 20 keV mass range using the Galactic halo observations of Suzaku X-ray astronomy satellite.

    To reveal evolution of clusters of galaxies and large-scale structures in the universe, it is essential to observe motion of hot intracluster medium with high-resolution X-ray spectroscopy. In this research, we developed a cryogenic TES microcalorimeter that could enable such observations, together with an adiabatic demagnetization refrigerator (ADR) that is operative under micro-gravity environment of satellites. The ADR that we developed has enough cooling performance, and we achieved energy resolution of 6.6 +/- 0.3 eV (FWHM) at 5.9 keV, after optimizing magnetic and electric shielding.

    今年度は小型断熱消磁冷凍機の更なる性能向上とX線マイクロカロリメータ動作に取り組んだ。
    まず冷凍機に関しては、放射シールドや配線の這い回しを徹底的に見直し、冷却環境の改善を目指した。その結果、0.084Kまで冷え、温度0.1Kを7時間以上保持できるようになった。また、計測装置の電気的な接地方法についても見直し、9μK(RMS値)の温度安定度を実現できるようになった。これらはいずれもX線マイクロカロリメータ動作を十分に実現できる性能である。
    次に、温度制御を行ないながら超伝導遷移端温度計(TES)の超伝導遷移の際の抵抗-温度特性を評価した。計測そのものは昨年度も実施しているが、温度制御をかけながら測定を行なうことができるようになった点が大きな改善点である。検出器ステージに磁気シールドを施し、センサ動作に向けた環境を整えた。TES温度計の評価の結果、小型断熱消磁冷凍機の環境できちんと超伝導転移することが確認できた。ただし、過去の測定では0.02K程度の温度幅で転移していたものが0.05K程度に広がっており、センサに外部磁場等の影響が若干残っているということが明らかになった。これについては今後さらなる改良が必要である。
    本研究で最終目標としていたX線マイクロカロリメータによる環境放射線の計測までは到らなかったものの、小型断熱消磁冷凍機を用いたX線マイクロカロリメータ動作の環境を整えて、実現にめどをつけることができた。

    The goals of this research are quick and precise localization of gamma-ray bursts (GRBs) which lead to prompt observations of afterglows, and investigation of origins and environments of GRBs from detailed X-ray and gamma-ray studies. We developed MAXI and succeeded in detecting and reporting GRBs. We also conducted basic development of X-ray spectrometers and GRB localization instruments. In addition, we analyzed the data obtained by satellites as HETE-2, Fermi, and Suzaku, and studied the correlation between the peak spectral energy and the luminosity, and the energy dependence of the X-ray/gamma-ray light curves.

    Aiming to realize TES (Transition-Edge Sensor) microcalorimeter with energy resolution of 2 eV and 16 x 16 pixels, we conducted following studies: (1) evaluation of microcalorimeter device and feed-back to the device fabrication, (2) research for readout system of 256 pixel microcalorimeter signals, (3) investigation of the interface to the adiabatic demagnetization refrigerator (ADR) onboard small scientific satellites. These results are summarized as the proposal document of the DIOS (Diffuse Intergalactic Oxygen Surveyor) mission utilizing a small satellite for mapping the warm-hot intergalactic medium (WHIM) known as the missing baryon in the universe, probing the ionized oxygen lines (OVII, OVIII).
    We fabricated a device using the sputtering machine at TMU, and conducted in-house processing at ISAS and AIST. The derived energy resolution was 4.8 eV (E/dE=1200) which is the Japanese record (world record is 2.4 eV by NIST group). We also fabricated a 256 pixel devices and succeeded in detecting X-rays with them. As for the readout system, signal readout with 8-input SQUID was investigated. Gamma-ray TES calorimeter attached with a tin absorber was tested, and 40 eV energy resolution at 60 keV was demonstrated. CPA (Chromium Potassium Alum) saltpill for ADR was made by a circulation method, and achieved 60 mK temperature at University of Wisconsin.
    In parallel, study of clusters of galaxies was performed using the Suzaku satellite launched in July 2005. Monte-carlo simulator including a ray-tracing of the X-ray telescope and the simplified simulation of X-ray CCD camera with a response matrix file (RMF) was developed to analyze spatially extended celestial targets like clusters of galaxies.

    The purpose of this research was to develop X-ray microcalorimetr using magnetic thermometers aiming for the detection of Oxygen emission lines from the warm-hot intergalactic medium. In this development, we succeeded to sense X-rays by metalic magnetic calorimeters firstly in Japan. The operation of magnetic calorimeters in adiabatic demagnetization refrigerators, which are considered to be only refrigeration method in space, were confirmed. Also future detectability of Oxygen lines by a wide field-of-view and high energy-resolution detectors were inspected in our Local Universe simulated by SPH. The CCD cameras onboard Suzaku satellite launched in 2005 achieved the best energy resolution for diffuse emission in Si detectors. We detected Galactic Oxygen emission with Suzaku, and obtained the tightest constraint for the emission from the intergalactic medium.

    We obtained new research results in the following four different areas. (1)To obtain a high quantum efficiency, we measured the R-T relation and crystal structure of Bismuth membranes, then fabricated TES calorimeters with a Bismuth absorber. The energy resolution remain at 20 eV, but we identified potential problems which restrict the energy resolution ; thermal conductivity at the boundary between the TES and the absorber, and thermal conductivity inside Bismuth membrane. (2)We fabricated a 16x16 format TES calorimeter array with electrodes and an X-ray absorber attached to every pixel., which demonstrates that such a large array can be fabricated with our fabrication process. (3)We investigated theoretical aspect of frequency division signal multiplex and developed a SQUID driver electronics which satisfies the requirement obtained from the theoretical study. (4)We studied warm/hot intergalactic matter associated with nearby cluster of galaxies, which will be useful for future astrophysical mission using the TES calorimeter arrays.

    We are developing high-energy-resolution X-ray microcalorimeters to observe X-ray emission from extended hot plasmas in the universe and to study their dynamical evolution. We have proposed a dedicated small X-ray mission to survey warm-hot intergalactic medium using oxygen emission lines with an array of TES microcalorimeters. We developed TES microcalonmeter array in collaboration with Waseda University, Seiko Instruments and Mitsubishi Heavy Industory. For a single pixel TES, we achieved energy resolution of 〜6 eV, close to the world record. Its performance including noise- and sensitivity-dependence on current and magnetic field was investigated. The electrodeposition technique of Sn or Bi was developed, and we successfully fabricated mushroom-shaped X-ray absorbers on TES microcalorimeters as an pixel array. It is essential to achieve large filling factor, adequate quantum efficiency, and uniform response, which is strongly required for the astronomical applications. Low heat capacity, fast thermalization, and high-Z material is suitable for an absorber, so that Sn or Bi are chosen. We recently fabricated a test model of the array sensor with 256 pixels, which produced X-ray signals successfully. We also developed a small adiabatic demagnetization refrigerator system capable for microcalorimeter testings outside of our laboratory. Another new type of instrument, magnetic calorimeters, was also developed and produced signals to 5.5 MeV alpha particles.

    The purpose of this research is to observe X-ray emission from extended hot plasmas in the universe and to study their dynamical evolution. The research activity consists of four areas : observational study of galaxies and clusters of galaxies in X-rays, theoretical study of cosmic plasmas, building and testing of microcalorimeter instrument on-board Astro-E2, and development of TES microcalorimeter system for future spectroscopic observations. In the X-ray observation, ASCA and Chandra revealed that many clusters have experienced mergers based on the temperature and metallicity distribution of bright systems. It is hoped that Astro-E2 will detect significant gas motion in many clusters of galaxies. We have proposed a dedicated small X-ray mission to survey warm-hot intergalactic medium using Oxygen emission lines with an array of TES calorimeters. Theoretical study on the possible heat source for the cluster gas was performed. Microcalorimeters for Astro-E2 have been produced, and the ground tests showed that most of the pixels have energy resolution as good as 6 eV. We also contributed fabrication of filter wheel and software system. We also developed TES calorimeter array in collaboration with Waseda University, Seiko Instruments and Mitsubishi Heavy Industory. For a single pixel TES, we achieved energy resolution of 6 eV, close to the world record, and fabricated a test model of the array sensor with 256 pixels, which produced X-ray signals successfully.

    バルクの臨界温度が0.92Kであるモリブデン薄膜を用いたX線マイクロカロリメータ用温度計(TES;Transition Edge Sensor)の試作を行ない、その性質を調べた。試作したTESはシリコンウェハにモリブデンと金をスパッタしたもので、モリブデンは10-50nm、金は0-400nmの範囲で厚みを変化させ、超伝導臨界温度への影響を調べた。その結果、相対的に金の厚みを増やすことにより、近接効果で薄膜の臨界温度が下がることが確認できた。ただし、製作時期によって厚みと臨界温度の関係が異なっていたことから、膜厚以外の要素も臨界温度に大きく影響していることがわかった。そこで、スパッタ時のアルゴンガスの圧力を0.1-0.3Pa(0.5-2mTorr)の範囲で変化させたところ、圧力が低くなるにつれて臨界温度が上昇することがわかった。これはアルゴンが少なくなるにつれて膜が緻密になることを示している。膜厚以外に重要と考えられるもう一つの要素は不純物である。本研究で使用したスパッタ装置はスパッタ速度が0.1nm/sとかなり遅く、また他の研究と併用しているため、不純物が多く取り込まれることになったと考えられる。したがって良質な膜を得るためには、蒸着速度を速めるほか、不純物そのものを減らしたり基板加熱によって水蒸気を取り除く等の工夫が必要である。
    並行して、昨年度に引き続きチタン-金薄膜を用いたTESの製作も行なった。こちらは蒸着時の不純物を取り除く工夫をしたところ、チタン100nm、金100nmで臨界温度0.19Kという理想的な性質を持つTESを製作することに成功した。
    本研究によって、0.1K程度で動作するTESの製作にめどがたったことから、今後はX線マイクロカロリメータへ応用し、高いエネルギー分解能を有するX線分光器の開発を行なっていく予定である。

    We studied new approaches to develop imaging microcalorimeters. We fabricated test models to confirm the new ideas experimentally. Major results are summarized below.
    (1) Micrormachine processing to fabricate microcalorimeter pixel structures
    We developed processes suited for imaging device. Finally we succeeded to fabricate calorimeter pixels with dry processes alone.
    (2) Fabrication of X-ray absorber on the calorimer pixel with micromachine processing
    We developed new processes utilizing plating to fabricate X-ray absorbers of "mushroom structure" which covers the calorimeter pixels with high covering efficiencies.
    (3) Ti-Au bilayer TES thermometers
    In our calorimeters, the temperature is sensed by the superconducting transition edge sensors (TES). We developed TES with Ti-Au bilayer membrane.
    (4) Microcalorimeter imaging readout system
    Number of signal lines allowed between the cryogenic to room temperatures is very limited. We developed a new method to multiplex calorimeter signals on frequency space. We developed a SQUID with multiple number of input coils and experimentally proved our new approach with a two-pixel calorimeter.
    (5) Evaluation of the X-ray microcalorimeters
    We evaluated the energy resolution of our X-ray microcalorimeter operating at 200 mK.The energy resolution was 99 eV.This is not good enough. We studied the extra noise factors which limit our resolutions.

    The purpose of this project is to perform observations and operations of ASCA in a collaboration between Japan and the United States of America, and to obtain scientific results from the X-ray observations on the X-ray binaries including compact objects, supernova remnants, active galactic nuclei, clusters of galaxies and the cosmic X-ray background. ASCA is the fourth Japanese X-ray satellite which was constructed in a collaboration between Japan and the U.S.A., and it was launched on February 20, 1993. The results of this project are summarized below :
    (1)We had national meetings and Japan-U.S.A.international meetings every year to select observation targets from the proposals, and discuss the organization of observation and operation of the satellite.
    (2)We examined the performance of the instruments onboard the satellite and provided the calibration database of the response of the instruments, including a time-dependent degradation of the performance of instruments.
    (3)We continuosly updated various software programs for data analysis, and produced an archival database for the convenience of international users.
    (4)We analyzed data from our own observations, and discussed the results with our partner country. These scientific results were presented at the international conferences and were published in academic journals.
    (5)All of the archival data were released to the scientists around the world with well-organized formats when the period of exclusive use by the owners expired.
    Because of the support by this grant-in-aid, we were able to perform well the ASCA observations and operations under the collaboration between Japan and the U.S.A.We obtained remarkable scientific results from the ASCA observations in various fields of X-ray astronomy.

    本研究は宇宙の色々な階層の天体に普遍的に存在する高温プラズマの物理状態を明らかにするために、X線天文衛星「あすか」のデーター解析を行うとともに、2000年2月に打ち上げられるASTRO-E衛星の基礎開発を行うことを目的とした。
    強磁場激変星EXHyaに含まれている白色矮星表面の高温プラズマを「あすか」で分光観測し、そこから得られる重元素からの輝線の強度を用いて、白色矮星の質量を求める全く新しい方法を確立した。この結果はAstrophysical Journal誌上で既に発表されている。この他、天空上に突然現れた新天体AXJ2315-592が強磁場激変星であることも「あすか」による観測によって突き止めた。
    ASTRO-Eに搭載されるX線望遠鏡の較正試験を行うために、宇宙研にあるX線ビームラインの立ち上げも行ってきた。較正システムは真空系、望遠鏡と検出器を同時に移動させるステージ系、およびデーター取得系からなる。本年度はこれらの系をそれぞれに信頼性をもって動作させ、さらに全系を組み合わせて較正試験を開始できるまでに立ち上げることに成功した。望遠鏡は1997年4月中旬から1999年にかけて宇宙研に搬入され較正試験に供される。本研究が較正試験系の立ち上げに果たした役割は大きい。
