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…
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…
Disentangling Multiple Gas Kinematic Drivers in the Perseus Galaxy Cluster
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +143
Galaxy clusters, the Universe's largest halo structures, are filled with 10-100 million degree X-ray-emitting gas. Their evolution is shaped by energetic processes such as feedback…
