Non-thermal ion acceleration at highly oblique non-relativistic shocks — •Naveen Kumar and Brian Reville — Max-Planck Institute for Nuclear Physics Heidelberg, Germany

Non-thermal acceleration of particles (both electrons and ions) at an oblique, non-relativistic shock is demonstrated by using one-dimensional large-scale particle-in-cell simulations. Our results show the generation of non-thermal ions at highly oblique shocks with acceleration efficiencies of ∼ 5% measured at the end of simulation runs. These results have important implications for understanding the non-thermal radiation generation at astrophysical sites such as supernova remnants.
