Magnetic Field Generation in Collisionless Shocks: Pattern Growth and Transport
TL;DR: In this article, the authors present results from three-dimensional particle simulations of collisionless shock formation, with relativistic counterstreaming ion-electron plasmas, and confirm the generation of strong magnetic and electric fields by a Weibel-like kinetic streaming instability.

Magnetic Field Generation in Collisionless Shocks; Pattern Growth and Transport
TL;DR: In this article, the authors present results from three-dimensional particle simulations of collisionless shocks with relativistic counter-streaming ion-electron plasmas, which confirm the generation of strong magnetic and electric fields by Weibel-like kinetic streaming instability, and demonstrate that the electromagnetic fields propagate far downstream of the shock.
Journal ArticleDOI
Non-Fermi Power-Law Acceleration in Astrophysical Plasma Shocks
TL;DR: In this paper, a power-law distribution of accelerated electrons is found in a relativistic collisionless plasma shock, which is different from Fermi acceleration and can explain more generally the origin of nonthermal radiation from shocked interstellar and circumstellar regions.
Journal ArticleDOI
Non-Fermi Power law Acceleration in Astrophysical Plasma Shocks
TL;DR: In this article, a power law distribution of accelerated electrons was found in a relativistic collisionless plasmas, which is different from Fermi acceleration, and the slopes of the electron distribution power laws were in concordance with the particle power law spectra inferred from observed afterglow synchrotron radiation in gamma ray bursts.
Journal ArticleDOI
Stochastically Induced Gamma-Ray Burst Wakefield Processes
TL;DR: In this paper, a numerical study of Gamma-Ray Burst - Circumburst Medium interaction and plasma preconditioning via Compton scattering is presented, which suggests that magnetic fields and plasma density filaments are created in the wakefield of prompt gamma-ray bursts, and that photon flux density gradient has a significant impact on particle acceleration in the burst head and wakefield.
