The Impact of Suzaku Measurements on Astroparticle Physics
  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.
