On "box" models of shock acceleration and electron synchrotron spectra
Luke O'C Drury, Peter Duffy, David Eichler +1
The recent detection of high energy gamma-rays coming from supernova remnants and active galactic nuclei has revived interest in the diffusive shock acceleration of electrons. In t…

Stochastic particle acceleration at shocks in the presence of braided magnetic fields
J. G. Kirk, P. Duffy, Y. A. Gallant
The theory of diffusive acceleration of energetic particles at shock fronts assumes charged particles undergo spatial diffusion in a uniform magnetic field. If, however, the magnet…

Cosmic Ray Hydrodynamics at Shock Fronts
P. Duffy, L. O'C. Drury, H. J. Voelk
When a magnetised, thermal plasma containing a shock wave efficiently accelerates Cosmic Rays (CR) a reaction is exerted on the fluid structure. The simplest description of this pr…
