| Research Abstract |
We have investigated the acceleration mechanisms of relativistic non-thermal particles in supernova remnants, pulsar wind nebulae and active galactic nuclei. We have studied elementary physical processes such as various plasma instabilities in collisionless shocks and made comparisons with gamma-ray observations. We have obtained many interesting results on particle acceleration and diffusion processes as well as X-ray and gamma-ray spectra.
