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.

Euclidean versus Non-Euclidean Gamma-Ray Bursts
TL;DR: In this paper, the authors classify gamma-ray bursts according to their observed durations and physical properties of their spectra, and find that long/hard bursts (of duration T90>2.5 s, and typical photon energy Ep 0.8 MeV, corresponding to BATSE's energy fluence hardness He32>3) show the strongest deviation from the three-dimensional Euclidean brightness distribution.
Journal ArticleDOI
THEORIES OF γ‐RAY BURSTSfn1
TL;DR: Theoretical models of cosmic gamma bursts fall into four categories: extra galactic models, flares, accretion onto collapsed stars, and exotic mechanisms as mentioned in this paper, and factors such as source properties, source dimensions, and radiation mechanisms are considered, in discussing these models.

Gamma-ray bursts from accreting black holes in neutron star mergers
M. Ruffert,H.T. Janka +1 more
TL;DR: In this article, the formation and the properties of the accretion torus around the stellar mass black hole which originates from the merging of two neutron stars were investigated by means of three-dimensional hydrodynamic simulations with a Eulerian PPM code.

Euclidean vs. non-Euclidean Gamma-Ray Bursts
TL;DR: In this paper, the authors classify gamma-ray bursts (GRBs) according to their observed durations and physical properties of their spectra, and find that long/hard bursts (of duration T_90 > 2.5 s, and typical photon energy E_p > 0.8 MeV corresponding to BATSE's energy fluence hardness H^e_{32} > 3) show the strongest deviation from the three-dimensional Euclidean brightness distribution.

Simulations of Gamma-Ray Bursts from External Shocks: Time Variability and Spectral Correlations
A. Panaitescu,Peter Mészáros +1 more
TL;DR: In this paper, burst spectra and time structures arising from synchrotron and inverse Compton scattering by nonthermal electrons accelerated in shocks that form during the interaction between a thin ultrarelativistic fireball and a stationary external medium were computed.
