Probing the All-sky Distribution of Soft X-ray Emission Associated with the Milky Way

Kazuki Ampuku, Ikuyuki Mitsuishi, Philip Kaaret +5

We present an all-sky analysis of soft X-ray emission associated with the Milky Way using HaloSat and ROSAT data, extending our previous study of five Galactic-plane regions to 330…

XRISM observations of the Perseus cluster along two arms: Chaotic ICM motions probed by resonant scattering

Annie Heinrich, Irina Zhuravleva, Congyao Zhang +13

XRISM has mapped gas velocities across the core of the Perseus cluster, separating the kinematic effects of mergers and AGN feedback. The physical properties of these motions remai…

XRISM reveals sloshing-driven gas motions in the core of Abell 2029

Yuusuke Uchida, Yuna Saito, Naomi Ota +13

We investigate the velocity structure of the intracluster medium (ICM) in the core of the relaxed cool-core cluster Abell 2029 using XRISM Resolve spectroscopy. We analyze combined…

Diagnosing the Fe line complex of the intracluster medium by XRISM high-resolution spectroscopy

K. Fukushima, L. Hirata, N. Y. Yamasaki +17

We aim to test the validity of the CIE framework in the ICM by performing line diagnostics based mainly on resolved Fe-K emission lines. Methods. We analyse Resolve full-array spec…

XRISM Reveals a Kinematically Coherent Core System of the Nearby Cool-Core Cluster Abell 2199

Kazunori Suda, Kyoko Matsushita, Kosuke Sato +14

We present the results of a deep 251 ks XRISM/Resolve observation of the cool core of the galaxy cluster Abell 2199. From the integrated spectrum of the central Reso…

Kinematics of the Weak Cool-Core Cluster A3571 Observed with XRISM: Low Cooling Rate Balanced by Low Heating Rate?

Hannah McCall, Irina Zhuravleva, Kyoko Matsushita +10

Most XRISM galaxy cluster observations to date have focused on AGN feedback or actively merging systems. The weak cool-core cluster A3571 was observed in four XRISM Cycle 1 pointin…

Probable Detection of a Cooler Gas Component in the Perseus Cluster with XRISM

Julian Meunier, Brian R. McNamara, Aurora Simionescu +36

We present an analysis of the temperature structure of the Perseus cluster atmosphere using XRISM Resolve observations. The average temperature rises from 3.3 keV near the nucleus…

Resonant scattering at the center of the galaxy cluster PKS 0745-191 with XRISM

Keita Tanaka, Megan Eckart, Kotaro Fukushima +11

We report evidence for the resonant scattering effect at the center of the galaxy cluster PKS 0745-191 with XRISM. We analyzed XRISM/Resolve commissioning-phase observations of the…

ASTRO-H White Paper - High Resolution Spectroscopy of Interstellar and Circumgalactic Gas in the Milky Way and Other Galaxies

F. Paerels, N. Yamasaki, N. Anabuki +23

We describe the potential of high resolution imaging spectroscopy with the SXS on ASTRO-H to advance our understanding of the interstellar- and circumgalactic media of our own Gala…

Exploring the Structure of Galaxy Clusters: XMM-Newton observations of the REFLEX-DXL clusters at z~0.3

Y. -Y. Zhang, H. Boehringer, A. Finoguenov +5

The precise determination of global properties of galaxy clusters, and their scaling relations, is a task of prime importance for the use of clusters as cosmological probes. We per…

Properties of the background of EPIC-pn onboard XMM-Newton

H. Katayama, I. Takahashi, Y. Ikebe +2

We have investigated the background properties of EPIC-pn onboard XMM-Newton to establish the background subtraction method. Count rates of the background vary violently by two ord…

Temperature Map of the Virgo Cluster of Galaxies Observed with ASCA

R. Shibata, K. Matsushita, N. Y. Yamasaki +5

The temperature distribution of the intracluster medium (ICM) in the Virgo cluster of galaxies has been derived from extensive mapping observations with ASCA covering an area of 19…
