Research Abstract |
We investigated both observationally and theoretically gamma-ray emitting supernova remnants and pulsar wind nebulae which generate Galactic cosmic-ray electrons and protons. With particle-in-cell simulations, we also studied processes of wave excitation and associated particle acceleration around the transition layer of collisionless shocks.
