A Deep Chandra View of Abell 2597: Bubbles, Shocks, Cold Fueling, and a Plasma Depletion Layer

Osase Omoruyi, Grant Tremblay, Stefi A. Baum +14

To examine how AGN feedback shapes the intracluster medium (ICM) and fuels black hole accretion in the cool-core galaxy cluster Abell 2597, we present deep (600 ks) Chandra X…

XRISM constraints on unidentified X-ray emission lines, including the 3.5 keV line, in the stacked spectrum of ten galaxy clusters

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +150

We stack 3.75 Megaseconds of early XRISM Resolve observations of ten galaxy clusters to search for unidentified spectral lines in the 2.5-15 keV band (rest frame), including t…

A Sharper View of the X-ray Spectrum of MCG--6-30-15 with XRISM, XMM-Newton and NuSTAR

Laura W. Brenneman, Daniel R. Wilkins, Anna Ogorzałek +15

We present a time-averaged spectral analysis of the 2024 XRISM observation of the narrow-line Seyfert-1 galaxy MCG--6-30-15, taken contemporaneously with XMM-Newton and NuSTAR. Our…

XRISM/Resolve observations of Hercules X-1: vertical structure and kinematics of the disk wind

Peter Kosec, Laura Brenneman, Erin Kara +11

X-ray binary accretion disk winds can carry away a significant fraction of the matter transferred from the companion and hence strongly affect the accretion flow and the long-term…

XRISM forecast for the Coma cluster: stormy, with a steep power spectrum

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +142

The XRISM Resolve microcalorimeter array measured the velocities of hot intracluster gas at two positions in the Coma galaxy cluster: 3'x3' squares at the center and at 6' (170 kpc…

Chemical enrichment of ICM within the A3266 cluster I: radial profiles

E. Gatuzz, J. Sanders, A. Liu +7

We present a detailed study of the elemental abundances distribution of the intracluster medium (ICM) within the A3266 cluster using {\it XMM-Newton} observations. This analysis us…
