Physics and Phenomenology of Weakly Magnetized, Relativistic Astrophysical Shock Waves Open
Weakly magnetized, relativistic collisionless shock waves are not only the natural offsprings of relativistic jets in high-energy astrophysical sources, they are also associated with some of the most outstanding displays of energy dissipat…

Physics of relativistic collisionless shocks. II. Dynamics of the background plasma Open
In this second paper of a series, we discuss the dynamics of a plasma entering the precursor of an unmagnetized, relativistic collisionless pair shock. We discuss how this background plasma is decelerated and heated through its interaction…

In this third paper of a series, we discuss the physics of the population of\naccelerated particles in the precursor of an unmagnetized, relativistic\ncollisionless pair shock. In particular, we provide a theoretical estimate of\ntheir sca…

In this first paper of a series dedicated to the microphysics of unmagnetized, relativistic collisionless pair shocks, we discuss the physics of the Weibel-type transverse current filamentation instability that develops in the shock precur…

Physics of Weibel-Mediated Relativistic Collisionless Shocks Open
We develop a comprehensive theoretical model of relativistic collisionless pair shocks mediated by the current filamentation instability. We notably characterize the noninertial frame in which this instability is of a mostly magnetic natur…

Collisionless shocks, that is shocks mediated by electromagnetic processes, are customary in space physics and in astrophysics. They are to be found in a great variety of objects and environments: magnetospheric and heliospheric shocks, su…
