High energy aspects of SNRs
Abstract
Supernova remnants (SNRs) are the main suppliers of thermal energy, heavy elements, cosmic rays, and so on. In other words, SNRs make diversity in the universe. These 15 years X-ray observations revealed us directly for the first time that shocks of SNRs accelerate high energy electrons and possibly protons. The quantitative study of cosmic-ray acceleration efficiency and the maximum energy of accelerated particles are also available with the new generation X-ray satellites. However, it is still an unsolved problem how much cosmic rays are really accelerated at SNR shocks. We will summarize the recent achievements on cosmic-ray acceleration in SNR shocks with X-ray and gamma-rays, including not only Chandra, XMM, Suzaku results, but also H.E.S.S. and Fermi observations.
