X-ray observations of Clusters of Galaxies

Abstract

X-ray observations of clusters provide key information on the dark matter, on the formation of structures in the Universe, and can be used to constrain the cosmological parameters. I review our current knowledge, with emphasis on recent XMM and Chandra results.
