A Multiphase Model for the Intracluster Medium [PDF]

Monthly Notices of the Royal Astronomical Society, 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

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).

Diffuse radio emission from the Intracluster medium [PDF]

New Astronomy Reviews, 2004
An important aspect of the radio emission from galaxy clusters is represented by the diffuse radio sources associated with the intracluster medium: radio halos, relics and mini-halos.

The Survival of Planetary Nebulae in the Intracluster Medium [PDF]

The Astrophysical Journal, 2005
The stellar population stripped from galaxies in clusters evolve under the extreme conditions imposed by the intracluster (IC) medium. Intracluster stars generally suffer very high systemic velocities, and evolve within a rarefied and extremely hot IC ...

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).

The Intracluster Medium in z > 1 Galaxy Clusters [PDF]

, 2000
The Chandra X-ray Observatory was used to obtain a 190 ks image of three high redshift galaxy clusters in one observation. The results of our analysis of these data are reported for the two z > 1 clusters in this Lynx field, including the most distant ...

Two-Temperature Intracluster Medium in Merging Clusters of Galaxies [PDF]

, 1999
We investigate the evolution of intracluster medium during a cluster merger, explicitly considering the relaxation process between the ions and electrons by N-body and hydrodynamical simulations.

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

Newcomers Meet the Intracluster Medium in the Coma Cluster [PDF]

, 2004
A main topic at this meeting is how galaxies are affected when they enter for the first time the cluster environment from the outskirts. Most of the times we are forced to infer the environmental effects indirectly, relying on systematic variations of ...

Ram pressure stripping in a viscous intracluster medium [PDF]

, 2008
In the recent literature there is circumstantial evidence that the viscosity of the intracluster medium may not be too far from the Spitzer value. In this letter, we present two-dimensional hydrodynamical simulations of ram pressure stripping of disc ...
