Abstract

Non-linear highly energetic plasma phenomena play a key-role in the understanding of astrophysical objects. We present plasma scenarios that provide a valid description for coherent radiation emission features observed from pulsar magnetospheres and for the self-consistent magnetic field generation essential for γ-ray burst synchrotron models. For this purpose we study ultra-relativistic plasma shell collisions with ensembles of up to 109 particles. We introduce the framework of the Particle-In-Cell (PIC) approach, details of the numerical realization and performance issues on the IBM REGATTA system of the Rechenzentrum Garching and the HITACHI supercomputer of the Leibniz Rechenzentrum. A final overview on simulation results and future perspectives closes the contribution.
