Series of review papers covering clusters of galaxies and related phenomena.Clusters of galaxies are the largest and most massive collapsed systems in the Universe. In addition to containing thousands of galaxies, these systems contain large amounts of hot, X-ray emitting gas and dark matter. This volume contains a series of review papers on this exciting and important astronomical topic by the world's leaders in this field. The volume is appropriate both as an introduction to this topic for physics and astronomy graduate students and as a reference source for professionals doing astronomical research.Clusters of galaxies are the largest and most massive collapsed systems in the Universe.
