A relativistic partially electromagnetic planar plasma shock

Abstract

We model relativistically colliding plasma by PIC simulations in one and two spatial dimensions, taking an ion-to-electron mass ratio of 400. Energy dissipation by a wave precursor of mixed polarity and different densities of the colliding plasma slabs results in a relativistic forward shock forming on millisecond timescales. The forward shock accelerates electrons to ultrarelativistic energies and reflects upstream ions, which drag the electrons along to preserve the plasma quasi-neutrality. No reverse shock forms. The shock may be representative for internal gamma ray burst shocks.
