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…
Mapping the Perseus Galaxy Cluster with XRISM: Gas Kinematic Features and their Implications for Turbulence
Congyao Zhang, Irina Zhuravleva, Annie Heinrich +19
In this paper, we present extended gas kinematic maps of the Perseus cluster by combining five new XRISM/Resolve pointings observed in 2025 with four Performance Verification datas…
Chemical enrichment in groups and clusters
François Mernier, Veronica Biffi
As building blocks of dust, rocky planets, and even complex life, the chemical elements heavier than hydrogen (H) and helium (He) - called "metals" in astronomy - play an essential…
Radial metal abundance profiles in the intra-cluster medium of cool-core galaxy clusters, groups, and ellipticals
François Mernier, Jelle de Plaa, Jelle S. Kaastra +10
The hot intra-cluster medium (ICM) permeating galaxy clusters and groups is not pristine, as it is continuously enriched by metals synthesised in Type Ia (SNIa) and core-collapse (…
Abundance and temperature distributions in the hot intra-cluster gas of Abell 4059
François Mernier, Jelle de Plaa, Lorenzo Lovisari +5
Using the EPIC and RGS data from a deep (~200 ks) XMM-Newton observation, we investigate the temperature structure (kT and sigma_T ) and the abundances of 9 elements (O, Ne, Mg, Si…
The growth of the galaxy cluster Abell 85: mergers, shocks, stripping and seeding of clumping
Y. Ichinohe, N. Werner, A. Simionescu +5
We present the results of deep Chandra, XMM-Newton and Suzaku observations of the nearby galaxy cluster Abell 85, which is currently undergoing at least two mergers, and in additio…
