Modelling the Energy Spectra of Radio Relics
Galaxies, 2021 Radio relics are diffuse synchrotron sources that illuminate shock waves in the intracluster medium. In recent years, radio telescopes have provided detailed observations about relics.

The nature of the motions of multiphase filaments in the centers of galaxy clusters
Frontiers in Astronomy and Space Sciences, 2023 The intracluster medium (ICM) in the centers of galaxy clusters is heavily influenced by the “feedback” from supermassive black holes (SMBHs). Feedback can drive turbulence in the ICM and turbulent dissipation can potentially be an important source of ...

Nonthermal support for the outer intracluster medium [PDF]
Astronomy & Astrophysics, 2010 We submit that non thermalized support for the outer intracluster medium in relaxed galaxy clusters is provided by turbulence, driven by inflows of intergalactic gas across the virial accretion shocks. We expect this component to increase briskly during the cluster development for z<1/2, due to three factors.

THE INTRAGROUP VERSUS THE INTRACLUSTER MEDIUM
The Astrophysical Journal, 2016 ABSTRACT Galaxy groups differ from clusters primarily by way of their lower masses, M ∼ 1014 M ⊙ versus M ∼ 1015 M ⊙. We discuss how mass affects the thermal state of the intracluster or the intragroup medium, specifically as to their entropy levels and radial ...

Enrichment of the Hot Intracluster Medium: Observations [PDF]
Space Science Reviews, 2018 Four decades ago, the firm detection of an Fe-K emission feature in the X-ray spectrum of the Perseus cluster revealed the presence of iron in its hot intracluster medium (ICM). With more advanced missions successfully launched over the last 20 years, this discovery has been extended to many other metals and to the hot atmospheres of many other galaxy ...

Mapping the intracluster medium temperature in the era of NIKA2 and MUSTANG-2 [PDF]
EPJ Web of Conferences, 2022 We present preliminary results from an on-going program that aims at mapping the intracluster medium (ICM) temperature of high redshift galaxy clusters from the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by Chandra and high ...

The X-Ray Intracluster Medium [PDF]
Symposium - International Astronomical Union, 1996 Clusters of galaxies are the largest aggregates of matter that have decoupled from the universal expansion and have approximately evolved to a proper dynamical equilibrium configuration. While in the optical they are just observed as dense concentrations of galaxies, they are seen in X-rays as continuously connected entities through the emission of the

XMM Observations of Abundances in the Intracluster Medium [PDF]
Symposium - International Astronomical Union, 2004 Based on XMM-Newton observations of M 87 and the Centaurus cluster, abundance profiles of various elements of the intracluster medium (ICM) are derived. The abundances of Si and Fe show strong decreasing gradients. In contrast, the O and Mg abundances are about half of the Si abundance at the center.From the gas mass to stellar mass ratio and the ...
