The Maximum Energy of Accelerated Particles in Relativistic Collisionless Shocks    [PDF]

Lorenzo Sironi, Anatoly Spitkovsky, Jonathan Arons

The afterglow emission from gamma-ray bursts (GRBs) is usually interpreted as synchrotron radiation from electrons accelerated at the GRB external shock, that propagates with relativistic velocities into the magnetized interstellar medium. By means of multi-dimensional particle-in-cell simulations, we investigate the acceleration performance of weakly magnetized relativistic shocks, in the magnetization range 0View original: http://arxiv.org/abs/1301.5333
