Numerical Studies of Cosmic Ray Injection and Acceleration
Hyesung Kang, T. W. Jones, U. D. J. Gieseler
A numerical scheme that incorporates a thermal leakage injection model into a combined gas dynamics and cosmic ray (CR, hereafter) diffusion-convection code has been developed. The…
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…
Ion injection and acceleration at modified shocks
U. D. J. Gieseler, T. W. Jones, Hyesung Kang
The theory of diffusive particle acceleration explains the spectral properties of the cosmic rays below energies of approx. 10^6 GeV as produced at strong shocks in supernova remna…
Monte-Carlo simulation of particle acceleration in braided magnetic fields
U. D. J. Gieseler, J. G. Kirk
Supernova remnants are expected to contain braided (or stochastic) magnetic fields, which are in some regions directed mainly perpendicular to the shock normal. For particle accele…
Particle acceleration at oblique shocks and discontinuities of the density profile
U. D. J. Gieseler, J. G. Kirk, Y. A. Gallant +1
In the theory of diffusive acceleration at oblique shock fronts the question of the existence of a discontinuity of energetic particle density is contentious. The resolution of thi…
