Abstract

Results from the Suzaku X-ray broad-band observations of clusters of galaxies are summarized. Aiming at understanding the physics of gas heating/particle acceleration and the cluster dynamical evolution, we search for non-thermal hard X-ray emission from merging clusters, particularly A2163 and the Bullet Cluster, based on the Suzaku and XMM-Newton/Chandra joint analyses. The observed hard X-ray emission is well represented by single- or multi-temperature thermal models, including super-hot (kT ~ 20 keV) gas. However, no significant non-thermal hard X-ray emission has been detected. Together with the presently available literature, the hard X-ray properties have been studied for about 10 clusters with Suzaku. The present status on Suzaku measurements of non-thermal X-ray emission and the cluster magnetic field are summarized and compared with those from the RXTE, BeppoSAX, and Swift satellites. The future prospects are briefly mentioned.
