X-Ray Spectra of Clusters of Galaxies

1981
X-ray spectroscopy has played a crucial role in the study of clusters of galaxies, possibly more so than in any other area. In one stroke, the detection of iron line emission from clusters by Mitchell et al. (1976) and Serlemitsos et al. (1977) showed that the dominant X-ray emission mechanism is thermal bremsstrahlung and that the intracluster gas is ...

The X-ray spectra of clusters of galaxies

Naturwissenschaften, 1979
The identification of extended sources of X-ray emission associated with clusters of galaxies has been one of the major achievements of X-ray astronomy. In this paper the present situation regarding the identification of X-ray clusters is reviewed and the relationship between X-ray and optical cluster properties is briefly discussed.

X-Ray Spectroscopy of Galaxy Clusters

1994
In the past few years, the results obtained with the X-ray satellites EXOSAT and GlNGA, combined with more ancient data from the EINSTEIN satellite (SSS and MPC), have greatly increased our knowledge of the spectroscopic properties of the intra-cluster medium.

The X-Ray View of Galaxy Clusters

2005
Clusters of galaxies are the most massive collapsed systems in the Universe. A typical luminous cluster (e.g., Coma cluster) is filled with a hot, 100 million degree, low density (10−3 cm−3) gas. In addition to the optically luminous galaxies and diffuse X-ray gas, clusters are dominated by dark matter.

X-ray Observations of Clusters of Galaxies

1988
Because Sarazin (1986) has written a very extensive review of the x-ray emission from clusters of galaxies I have allowed myself considerable leeway in writing this review. In particular it has allowed me to be incomplete in my references and to omit certain topics.
