Turbulence in the Intracluster Medium

2014
We review our knowledge about turbulence in the intracluster medium, a very hot, dilute plasma that permeates clusters of galaxies. A thorough understanding of turbulence in the intracluster medium is crucial for the use of clusters to determine cosmological parameters.

Metals in the intracluster medium

AIP Conference Proceedings, 2012
We derived radial abundance profiles of O, Mg, Si, S and Fe in the intracluster medium (ICM) of several clusters and groups of galaxies up to about 0.3 r180 with Suzaku and those of Fe in 28 nearby brightest clusters of galaxies up to 0.3-0.5 r180 with XMM. Within 0.05 r180, Fe abundance scatters from 0.5 to 1 solar.

The Intracluster Medium

1992
Clusters of galaxies are full of hot, diffuse plasma, with typical temperatures and electron densities of T ~ 7x107 K and n e ~ 10-3 cm-3, This intraclustermedium (ICM) produces copious X-ray emission, and typical cluster X-ray luminositiesare L x ~ 1043 - 1045 ergs s-1.

Imaging the Hot Intracluster Medium

1992
Clusters of galaxies contain large amounts of hot, diffuse x—ray emitting gas. Observations of this gas can be used to measure the gas mass, the cluster virial mass, and the cluster morphology. From these measurements. a lower limit to the baryonic mass in clusters, the formation efficiency of galaxies in different environments, and the presence and ...

Evolution of Clusters and the Intracluster Medium

1993
I review observations and theoretical models of evolution of gas in clusters of galaxies. The mass of hot gas is an important component of clusters of galaxies, equalling or exceeding the total mass in galaxies in most clusters. The hot gas also traces the gravitational potential of the cluster, giving better measurements of the total mass of a cluster
