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

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.

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.

Intracluster medium through three years of WMAP [PDF]
, 2006 Wilkinson Microwave Anisotropy Probe (WMAP) has provided us with the yet highest resolution all-sky maps of the Cosmic Microwave Background. As a result of thermal Sunyaev-Zel'dovich effect, clusters of galaxies are imprinted as tiny, poorly resolved ...

Metal enrichment of the intracluster medium: SN‐driven galactic winds [PDF]
, 2009 We investigate the role of supernova (SN)-driven galactic winds in the chemical enrichment of the intracluster medium (ICM). Such outflows on galactic scales have their origin in huge star forming regions and expel metal enriched material out of the ...

A Multiphase Model for the Intracluster Medium [PDF]
, 1999 Constraints on the clustered mass density \Omega_m of the universe derived from the mean intracluster gas fraction of X-ray clusters may be biased by a single-phase assumption for the thermodynamic structure of the intracluster medium (ICM). We propose a

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.

The Intracluster Medium: An Invariant Stellar Initial Mass Function [PDF]
, 1997 Evidence supporting the hypothesis of an invariant stellar Initial Mass Function is strong and varied. The intra-cluster medium in rich clusters of galaxies is one of the few contrary locations where recent interpretations of the chemical abundances have

Electron Preacceleration in Weak Quasi-perpendicular Shocks in High-beta Intracluster Medium [PDF]
Astrophysical Journal, 2019 Giant radio relics in the outskirts of galaxy clusters are known to be lit up by the relativistic electrons produced via diffusive shock acceleration (DSA) in shocks with low sonic Mach numbers, Ms ≲ 3.
