A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87

XRISM Collaboration, M. Audard, H. Awaki +138

The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…

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…

Cosmic-ray and Interstellar Gas Properties in the Solar Neighborhood Revealed by Diffuse Gamma Rays

Tsunefumi Mizuno, Katsuhiro Hayashi, Hinako Ochi +3

To investigate the interstellar medium (ISM) and Galactic cosmic rays (CRs) in the solar neighborhood, we analyzed -ray data by Fermi Large Area Telescope (LAT) for five nearby…

XRISM Spectroscopy of the Stellar-Mass Black Hole 4U 1630-472 in Outburst

Jon M. Miller, Misaki Mizumoto, Megumi Shidatsu +23

We report on XRISM/Resolve spectroscopy of the recurrent transient and well-known black hole candidate 4U 1630472 during its 2024 outburst. The source was captured at the end of…

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…
