The Impact of Suzaku Measurements on Astroparticle Physics. (arXiv:1211.1115v1 [astro-ph.CO]):
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 analyzes. The
observed hard X-ray emission is well represented by the single- or
multi-temperature thermal models including super-hot (kT~20 keV) gas. On the
other hand, 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.
