Turbulence decay in the density-stratified intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Turbulence evolution in a density-stratified medium differs from that of homogeneous isotropic turbulence described by the Kolmogorov picture. We evaluate the degree of this effect in the intracluster medium (ICM) with hydrodynamical simulations. We find

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).

Turbulence in the intracluster medium: simulations, observables & thermodynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 We conduct two kinds of homogeneous isotropic turbulence simulations relevant for the intracluster medium (ICM): (i) pure turbulence runs without radiative cooling; (ii) turbulent heating$+$radiative cooling runs with global thermal balance.

Intracluster medium of the merging cluster Abell 3395 [PDF]
The Astrophysical Journal, 2011 We present a detailed imaging and spectral analysis of the merging environment of the bimodal cluster A3395 using X-ray and radio observations. X-ray images of the cluster show five main constituents of diffuse emission : A3395 NE, A3395 SW, A3395 NW ...

A Heating Mechanism via Magnetic Pumping in the Intracluster Medium [PDF]
The Astrophysical Journal, 2023 Turbulence driven by active galactic nuclei activity, cluster mergers, and galaxy motion constitutes an attractive energy source for heating the intracluster medium (ICM).

Exploring the relation between turbulent velocity and density fluctuations in the stratified intracluster medium [PDF]
Astronomy & Astrophysics, 2021 Context. The dynamics of the intracluster medium (ICM) is affected by turbulence driven by several processes, such as mergers, accretion and feedback from active galactic nuclei. Aims.

Populations of Magnetized Filaments in the Intracluster Medium and the Galactic Center [PDF]
Astrophysical Journal Letters, 2022 Magnetized radio filaments are found in abundance in the inner few hundred parsecs of our galaxy. Progress in understanding this population of filaments has been slow over the last few decades, in part due to a lack of detection elsewhere in the galaxy ...

The chemical evolution of galaxy clusters: Dissecting the iron mass budget of the intracluster medium [PDF]
Astronomy & Astrophysics, 2020 Aims. We study the chemical evolution of galaxy clusters by measuring the iron mass in the ICM after dissecting the abundance profiles into different components. Methods.

The complex interplay of AGN jet-inflated bubbles and the intracluster medium [PDF]
Monthly notices of the Royal Astronomical Society, 2023 We use SWIFT, a smoothed particle hydrodynamics code, to simulate the evolution of bubbles inflated by active galactic nuclei (AGN) jets, as well as their interactions with the ambient intracluster medium (ICM).

Plasma Physics of the Intracluster Medium
, 2022 This Chapter provides a brief tutorial on some aspects of plasma physics that are fundamental to understanding the dynamics and energetics of the intracluster medium (ICM). The tutorial is split into two parts: one that focuses on the thermal plasma component -- its stability, viscosity, conductivity, and ability to amplify magnetic fields to dynamical
