Long-time evolution of magnetic fields in relativistic GRB shocks
Mikhail V. Medvedev, Massimiliano Fiore, Ricardo A. Fonseca +2
We investigate the long-time evolution of magnetic fields generated by the two-stream instability at ultra- and sub-relativistic astrophysical collisionless shocks. Based on 3D PIC…
Kinetics of Particles in Relativistic Collisionless Shocks
Mikhail V. Medvedev, Luis O. Silva, Ricardo A. Fonseca +2
Charged plasma particles form an anisotropic counter-streaming distribution at the front of a shock. In the near- and ultra-relativistic regimes, Weibel (or two-stream) instability…
Interpenetrating plasma shells: near-equipartition magnetic field generation and non-thermal particle acceleration
L. O. Silva, R. A. Fonseca, J. Tonge +3
We present the first three-dimensional fully kinetic electromagnetic relativistic particle-in-cell simulations of the collision of two interpenetrating plasma shells. The highly ac…
