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.

Missing Thermal Energy of the Intracluster Medium [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
The Sunyaev-Zel'dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photons off hot electrons in the intracluster medium (ICM). We report a 9-sigma

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).

A Two-Temperature Model of the Intracluster Medium [PDF]

The Astrophysical Journal, 1998
We investigate evolution of the intracluster medium (ICM), considering the relaxation process between the ions and electrons. According to the standard scenario of structure formation, ICM is heated by the shock in the accretion flow to the gravitational

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 ...

The Sunyaev-Zel'dovich temperature of the intracluster medium [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
The relativistic Sunyaev-Zel'dovich (SZ) effect offers a method, independent of X-ray, for measuring the temperature of the intracluster medium (ICM) in the hottest systems. Here, using N-body/hydrodynamic simulations of three galaxy clusters, we compare

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

The Astrophysical Journal, 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 ...

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.

Plasma 2020 - Intracluster Medium Plasmas [PDF]

, 1910
Galaxy clusters are the largest and most massive bound objects resulting from cosmic hierarchical structure formation. Baryons account for somewhat more than 10% of that mass, with roughly 90% of the baryonic matter distributed throughout the clusters as
