Time dependent cosmic-ray shock acceleration with self-consistent injection
U. D. J. Gieseler, T. W. Jones, Hyesung Kang
One of the key questions to understanding the efficiency of diffusive shock acceleration of the cosmic rays (CRs) is the injection process from thermal particles. A self-consistent…

First order Fermi acceleration at multiple oblique shocks
U. D. J. Gieseler, T. W. Jones
Numerical results for particle acceleration at multiple oblique shocks are presented. We calculate the steady state spectral slope of test particles accelerated by the first order…
