DESCRIPTION:Rapidly rotating neutrons stars and black holes are the centra
 l engines of some of the most\nextreme astrophysical phenomena such as gam
 ma-ray bursts\, pulsars\, X-ray binaries\, binary\nmergers or active galac
 tic nuclei. The activity of these compact objects is often associated\nwit
 h the creation and the launching of a relativistic magnetized plasmas acco
 mpanied by\nefficient particle acceleration and non-thermal radiation\, bu
 t the underlying physical\nmechanisms are still poorly understood. The par
 ticle-in-cell method is well-suited to model\nthese processes from first p
 rinciples. Recent numerical simulations have clearly established\nthat rel
 ativistic magnetic reconnection within the magnetosphere of pulsars and bl
 ack holes\nplays a crucial role in dissipating magnetic energy which is th
 en efficiently channeled into\nenergetic particles and high-energy radiati
 on. Results will be discussed in the context of\ngamma-ray pulsars\, mergi
 ng binary neutron stars and weakly accreting Kerr black holes.
