Thermal or Non-thermal? Diffuse emission in the infall region of stacked galaxy groups

E. Bulbul, X. Zhang, Z. Ding +16

The faint infall regions surrounding the virial radius of galaxy groups remain largely unexplored due to their low X-ray surface brightness. Using the large statistical power of SR…

Accurate Determination of Chemical Abundances near a Supermassive Black Hole

The XRISM collaboration

The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…

High Spectral Resolution X-ray Observations of the Evolved Supermassive Stellar Binary System Carinae - Iron K Band Profile Revealed with XRISM

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +138

The supermassive binary system, Carinae, is experiencing enormous wind-driven mass loss at a rate unparalleled in the rest of the Galaxy. Their wind-wind collision (WWC) contin…

The Quiescent Merging Nature of the Coma Cluster Revealed by ICM Velocity Structure

E. Gatuzz, J. Sanders, A. Liu +4

The hot gas permeating galaxy clusters-the intracluster medium (ICM)-is a key tracer of their assembly history and internal dynamics. Understanding the motion of this gas provides…

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 Centaurus cluster I: radial profiles

Efrain Gatuzz, J. S. Sanders, K. Dennerl +6

We examine deep {\it XMM-Newton} EPIC-pn observations of the Centaurus cluster to study the hot intracluster medium (ICM) and radial metal distributions within such an environment.…
