Diagnosing the Fe line complex of the intracluster medium by XRISM high-resolution spectroscopy
K. Fukushima, L. Hirata, N. Y. Yamasaki +17
We aim to test the validity of the CIE framework in the ICM by performing line diagnostics based mainly on resolved Fe-K emission lines. Methods. We analyse Resolve full-array spec…
Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +143
The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last 12 Gyr. Whereas cluster outskirts are…
XRISM Reveals a Kinematically Coherent Core System of the Nearby Cool-Core Cluster Abell 2199
Kazunori Suda, Kyoko Matsushita, Kosuke Sato +14
We present the results of a deep 251 ks XRISM/Resolve observation of the cool core of the galaxy cluster Abell 2199. From the integrated spectrum of the central Reso…
Dynamics of AGN feedback in the X-ray bright East and Southwest arms of M87, mapped by XRISM
A. Simionescu, C. Kilbourne, H. R. Russell +24
As the central galaxy in the nearest cluster, M87 provides the best spatial resolution for disentangling the complex interactions between AGN jets and the surrounding environment.…
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…
Distribution of Metals and Multi-Temperature Gas in the Cores of Nearby Galaxy Groups
Dimitris Chatzigiannakis, Aurora Simionescu, François Mernier
Previous studies of galaxy clusters have focused extensively on the effects of active galactic nuclei (AGN) feedback on the chemical evolution of the intra-cluster medium (ICM). Ho…
Core to Cosmic Edge: SIMBA-C's New Take on Abundance Profiles in the Intragroup Medium at z = 0
Aviv Padawer-Blatt, Zhiwei Shao, Renier T. Hough +9
We employ the SIMBA-C cosmological simulation to study the impact of its upgraded chemical enrichment model (Chem5) on the distribution of metals in the intragroup medium (IGrM). W…
Discovery of inverse-Compton X-ray emission and estimate of the volume-averaged magnetic field in a galaxy group
F. Mernier, N. Werner, J. Bagchi +6
Observed in a significant fraction of clusters and groups of galaxies, diffuse radio synchrotron emission reveals the presence of relativistic electrons and magnetic fields permeat…
The cycle of metals in the infalling elliptical galaxy NGC 1404
F. Mernier, N. Werner, Y. Su +6
Hot atmospheres pervading galaxy clusters, groups, and early-type galaxies are rich in metals, produced during epochs and diffused via processes that are still to be determined. Wh…
Constraining the origin and models of chemical enrichment in galaxy clusters using the Athena X-IFU
F. Mernier, E. Cucchetti, L. Tornatore +16
The chemical enrichment of the Universe at all scales is related to stellar winds and explosive supernovae phenomena. Metals produced by stars and later spread at the mega-parsec s…
Powerful AGN jets and unbalanced cooling in the hot atmosphere of IC 4296
R. Grossová, N. Werner, K. Rajpurohit +13
We present new Karl G. Jansky Very Large Array (VLA, 1.5 GHz) radio data for the giant elliptical galaxy IC 4296, supported by archival radio, X-ray (Chandra, XMM-Newton) and optic…
Magnetic fields and extraordinarily bright radio emission in the X-ray faint galaxy group MRC 0116+111
F. Mernier, N. Werner, J. Bagchi +4
MRC 0116+111 is a nearby () poor galaxy group, which was previously known for exhibiting a bright diffuse radio emission with no central point-like source, presumably rela…
X-ray study of the double radio relic Abell 3376 with Suzaku
I. Urdampilleta, H. Akamatsu, F. Mernier +5
We present an X-ray spectral analysis of the nearby double radio relic merging cluster Abell 3376 ( = 0.046), observed with the XIS instrument. These deep (360 ks…
CHEERS: The chemical evolution RGS sample
J. de Plaa, J. S. Kaastra, N. Werner +17
The chemical yields of supernovae and the metal enrichment of the hot intra-cluster medium (ICM) are not well understood. This paper introduces the CHEmical Enrichment RGS Sample (…
Origin of central abundances in the hot intra-cluster medium - I. Individual and average abundance ratios from XMM-Newton EPIC
François Mernier, Jelle de Plaa, Ciro Pinto +5
The hot intra-cluster medium (ICM) is rich in metals, which are synthesized by supernovae (SNe) explosions and accumulate over time into the deep gravitational potential well of cl…
An XMM-Newton view of the M17 nebula
Francois Mernier, Gregor Rauw
We present the analysis of an XMM-Newton observation of the M17 nebula. The X-ray point source population consists of massive O-type stars and a population of probable low-mass pre…
