abstract = {The current paradigm of cosmic-ray (CR) origin states that
the greater part of galactic CRs is produced by supernova
remnants. The interaction of supernova ejecta with the
interstellar medium after a supernova's explosions results
in shocks responsible for CR acceleration via diffusive
shock acceleration (DSA). We use particle-in-cell (PIC)
simulations and a combined PIC-magnetohydrodynamic (PIC-MHD)
technique to investigate whether DSA can occur in oblique
high Mach number shocks. Using the PIC method, we follow the
formation of the shock and determine the fraction of the
particles that gets involved in DSA. With this result, we
use PIC-MHD simulations to model the large-scale structure
of the plasma and the magnetic field surrounding the shock
and find out whether or not the reflected particles can
generate upstream turbulence and trigger DSA. We find that
the feasibility of this process in oblique shocks depends
strongly on the Alfvénic Mach number, and the DSA process
is more likely to be triggered at high Mach number shocks.},
