Two-dimensional particle-in-cell simulations of highly oblique collisionless shock acceleration of electrons and ions

I present the results of long-term, high-resolution two-dimensional particle-in-cell (PIC) simulations of the highly oblique collisionless shock acceleration of particles, specifically electrons and ions. I place particular emphasis on the choice of shock excitation methods in PIC simulations and demonstrate the significance of kinetic plasma processes occurring at collisionless shocks in the generation of non-thermal particles at shocks. These kinetic plasma processes are exclusively captured in PIC simulations of collisionless shocks. These high Mach number (Alfvenic and sonic) and highly oblique shocks are relevant to various astrophysical objects, such as young supernova remnants and stellar winds, and can help in understanding the origin of non-thermal radiation from these objects.
