TLDR
The recent discovery of GRB afterglow has demonstrated that we are on the right track towards the resolution of this long standing puzzle as discussed by the authors, and the current understanding implies that GRBs signal the birth of stellar mass black holes.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.

TL;DR: In this article, a comprehensive sample of all gamma-ray burst (GRB) afterglows with known distances is presented, and their conical opening angles are derived based on observed broadband breaks in their light curves.

Accretion Models of Gamma‐Ray Bursts
TL;DR: In this article, it was shown that if the viscosity parameter a in the NDAF has a standard value of D0.1, these models can explain short gamma-ray bursts with durations under a second, but they are unlikely to produce long GRBs with tens or hundred of seconds.

Gamma-ray bursts and the fireball model
Tsvi Piran,Tsvi Piran +1 more
TL;DR: In this article, it was shown that the inner engine that accelerates the relativistic flow is hidden from direct observations and therefore it is difficult to infer its structure directly from current observations.
Journal ArticleDOI
Unsteady outflow models for cosmological gamma-ray bursts
Martin J. Rees,Peter Mészáros +1 more
TL;DR: In this paper, the authors proposed a mechanism for cosmological bursts that requires less extreme assumptions (in respect of Gamma-values, freedom from baryonic contamination, etc.) than earlier proposals.
Journal ArticleDOI
Gamma-ray bursts as the death throes of massive binary stars
TL;DR: In this article, it was shown that gamma-ray bursts are created in the mergers of double neutron star binaries and black hole neutron star binary at cosmological distances, and the strongest bursts should be found close to, but not at the centers of, galaxies at redshifts of order 0.1, and should be accompanied by bursts of gravitational radiation from the spiraling-in binary which could be detected by LIGO.

Optical and long wavelength afterglow from gamma-ray bursts
Peter Mészáros,Martin J. Rees +1 more
TL;DR: In this article, the authors discuss the evolution of cosmological gamma-ray burst remnants, consisting of the cooling and expanding fireball ejecta together with any swept-up external matter.
Journal ArticleDOI
Fluid dynamics of relativistic blast waves
TL;DR: In this paper, a fluid dynamical treatment of an ultra-relativistic spherical blast wave enclosed by a strong shock is presented, and a simple similarity solution describing the explosion of a fixed amount of energy in a uniform medium is derived, and generalized to include cases in which power is supplied by a central source and the density of the external medium varies with radius.
