Research Abstract

The present research aimed at demonstrating our conjecture, that galaxies in a galaxy cluster must be interacting strongly with the hot plasma filling the cluster volume, and hence are falling to the center. Through X-ray observations using Suzaku and other means, we successfully revealed the presence of a large-scale ordered magnetic structure in the center of some clusters, and obtained evidence of plasma heating process therein. Incorporating optical data, we also obtained evidence that galaxies have actually been falling to the center of the cluster over the cosmological time scale.
