TLDR
In this article, the theory of first order Fermi acceleration at collisionless astrophysical shock fronts is reviewed and it is argued that the wave amplitude is probably non-linear within sufficiently strong astrophysical shocks.About:

The physics of gamma-ray bursts
TL;DR: A review of the current theoretical understanding of the physical processes believed to take place in GRB's can be found in this article, where the authors focus on the afterglow itself, the jet break in the light curve, and the optical flash that accompanies the GRB.
Journal ArticleDOI
Gamma-ray bursts
TL;DR: In this article, the interplay between these observations and theoretical models of the prompt gamma-ray burst and its afterglow is reviewed, and a model of the burst's origin and mechanism is proposed.
Journal ArticleDOI
The interstellar environment of our galaxy
TL;DR: In this article, the authors present the current knowledge and understanding of the interstellar medium of our galaxy and discuss the interaction of these interstellar constituents, both with each other and with stars, in the framework of the general galactic ecosystem.

Electron acceleration from contracting magnetic islands during reconnection
TL;DR: Here it is shown that electrons gain kinetic energy by reflecting from the ends of the contracting ‘magnetic islands’ that form as reconnection proceeds, analogous to the increase of energy of a ball reflecting between two converging walls.

Evidence for shock acceleration of high-energy electrons in the supernova remnant SN1006
Katsuji Koyama,Robert Petre,Eric V. Gotthelf,Eric V. Gotthelf,Una Hwang,M. Matsuura,M. Ozaki,Stephen S. Holt +7 more
TL;DR: In this paper, X-ray observations of the remnant of supernova 1006, made by the ASCA satellite, indicate that emission from the edges of the supernova remnant shell is dominated by radiation from electrons accelerated to energies of ~ 100 TeV within the shock front.

A theory of the interstellar medium - Three components regulated by supernova explosions in an inhomogeneous substrate
TL;DR: In this paper, a self-consistent model of the interstellar medium was developed to account for the observed pressure of interstellar clouds, the galactic soft X-ray background, the O VI absorption line observations, the ionization and heating of much of the galaxy, and the motions of the clouds.

An introduction to the theory of diffusive shock acceleration of energetic particles in tenuous plasmas
TL;DR: In this article, the central idea of diffusive shock acceleration is presented from microscopic and macroscopic viewpoints; applied to reactionless test particles in a steady plane shock, the mechanism is shown to produce a power law spectrum in momentum with a slope which, to lowest order in the ratio of plasma to particle speed, depends only on the compression in the shock.
