Coherent Radiation in Gamma-Ray Bursts and Relativistic Collisionless Shocks
نویسنده
چکیده
We suggest that coherent radiation may occur in relativistic collisionless shocks via twostream Weibel instabilities. The coherence amplifies the radiation power by many orders [∼ 10 in Gamma-Ray Bursts (GRBs)] and particles cool very fast before being randomized. We imply (1) GRBs accompany strong infrared emission, (2) protons efficiently transfer energy to electrons and (3) prompt GRBs might be the upscattered coherent radiation.

On the Structure of Relativistic Collisionless Shocks in Electron-ion Plasmas
Relativistic collisionless shocks in electron-ion plasma are thought to occur in the afterglow phase of Gamma-Ray Bursts (GRBs), and in other environments where relativistic flows interact with the interstellar medium. A particular regime of shocks in an unmagnetized plasma has generated much interest for GRB applications. In this paper we present ab-initio particle-in-cell simulations of unmag...
متن کاملThe Cosmic Ray Precursor of Relativistic Collisionless Shocks: a Missing Link in Gamma-ray Burst Afterglows
Collisionless shocks are commonly argued to be the sites of cosmic ray (CR) acceleration. We study the influence of CRs on weakly magnetized relativistic collisionless shocks and apply our results to external shocks in gamma-ray burst (GRB) afterglows. The common view is that the transverse Weibel instability (TWI) generates a small-scale magnetic field that facilitates collisional coupling and...
متن کاملNonlinear Particle Acceleration in Relativistic Shocks
Monte Carlo techniques are used to model nonlinear particle acceleration in parallel collisionless shocks of various speeds, including mildly relativistic ones. When the acceleration is efficient, the backreaction of accelerated particles modifies the shock structure and causes the compression ratio, r, to increase above test-particle values. Modified shocks with Lorentz factors, γ0 . 3, can ha...
متن کاملDiffusive Synchrotron Radiation from Relativistic Shocks of Gamma-Ray Burst Sources
The spectrum of electromagnetic emission generated by relativistic electrons scattered on small-scale random magnetic fields is considered within the context of gamma-ray bursts. This problem has been considered previously by Medvedev (2000). However, Medvedev’s treatment contained several errors that are rectified here. It is shown that a correct treatment of the random nature of the smallscal...
متن کاملNew Relativistic Particle-In-Cell Simulation Studies of Prompt and Early Afterglows from GRBs
Nonthermal radiation observed from astrophysical systems containing relativistic jets and shocks, e.g., gammaray bursts (GRBs), active galactic nuclei (AGNs), and microquasars commonly exhibit power-law emission spectra. Recent PIC simulations of relativistic electron-ion (or electron-positron) jets injected into a stationary medium show that particle acceleration occurs within the downstream j...
