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.

The Dynamics and Light Curves of Beamed Gamma-Ray Burst Afterglows
TL;DR: In this article, the effects of beaming on burst remnant dynamics and afterglow emission were explored, and it was shown that the burst's evolution changes qualitatively once its bulk Lorentz factor Γ 1/εm is beamed into angle εm.

TL;DR: In this paper, the authors reported the detection of bright optical emission from GRB990123 while the burst was still in progress, and the redshift of this burst, z ≈ 1.6, implies a peak optical luminosity of 5× 1049 −1.
Journal ArticleDOI
Can Internal Shocks Produce the Variability in Gamma-Ray Bursts?
TL;DR: In this article, the authors discussed the possibility that gamma-ray bursts result from internal shocks in ultrarelativistic matter and used a simple model to calculate the temporal structure and estimate the efficiency of this process.
Journal ArticleDOI
The radio afterglow from the γ-ray burst of 8 May 1997
TL;DR: In this paper, the authors reported a variable radio source within the error box of GRB970508 and coincident with the optical transient, suggesting that this is the much-sought-after radio counterpart of a GRB.
