| Research Abstract |
Large-scale 2D PIC simulations of collision-less shocks reveal that electrons are effectively accelerated by the electron shock surfing acceleration mechanism with using a large ion-to-electron mass ratio in a very-high Alfven Mach number regime. The results imply that electrons can be accelerated effectively to relativistic energies at supernova remnant shocks.
