Resum

In this talk I will briefly describe our numerical models for two different classes of Astrophysical sources of high-energy radiation: namely Pulsar Wind Nebulae and (long) GRB projenitors in the magnetar scenario. Under some respects, in spite of many differences, these two objects may share some common physics, especially the magnetic mechanism needed to collimate the polar relativistic jets. I will also discuss the plasma diagnostic techniques that we use to infer non-thermal emission (in the case of PWNe) and some recent important observations in the gamma rays. Finally, and only under request!, I will briefly summarize the main features and the latest developments of the GRMHD code ECHO employed for the simulations.
