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.

TL;DR: In this paper, the authors reported the detection of a transient and fading optical source in the error box associated with the burst GRB970228, less than 21 hours after the burst, suggesting that the burst occurred in that galaxy and thus that γ-ray bursts in general lie at cosmological distance.

Relativistic fireballs: energy conversion and time-scales
Martin J. Rees,Peter Mészáros +1 more
TL;DR: In this paper, the expansion energy of a relativistic fireball can be reconverted into radiation when it interacts with an external medium, and the corresponding time-scale in the frame of the observer is of the order of seconds.

Generation of Magnetic Fields in the Relativistic Shock of Gamma-Ray Burst Sources
TL;DR: In this article, the relativistic two-stream instability can naturally generate strong magnetic fields with 10-5-10-1 of the equipartition energy density, in the collisionless shocks of gamma-ray burst (GRB) sources.
