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 Propagation of Relativistic Jets in External Media
TL;DR: In this paper, the authors present a self-consistent, analytic model that follows the evolution of the jet and its cocoon and describes their interaction, and they show that the critical parameter that determines the properties of a jet-cocoon system is the dimensionless ratio between the jet's energy density and the rest-mass energy density of the ambient medium.
Journal ArticleDOI
Relativistic outflows from remnants of compact object mergers and their viability for short gamma-ray bursts
TL;DR: In this paper, general relativistic hydrodynamic models of the launch and evolution of relativists and winds, driven by thermal energy deposition, possibly due to neutrino-antineutrino annihilation, in the close vicinity of black hole-accretion torus systems are presented.

The evolution of a structured relativistic jet and gamma-ray burst afterglow light curves
Pawan Kumar,Jonathan Granot +1 more
TL;DR: In this paper, the authors carried out a numerical hydrodynamical modeling for the evolution of a relativistic collimated outflow as it interacts with the surrounding medium and calculate the light curve resulting from synchrotron emission of the shocked fluid.

The 2175 Å Dust Feature in a Gamma-Ray Burst Afterglow at Redshift 2.45
Thomas Krühler,A. Kupcu Yoldas,Jochen Greiner,C. Clemens,Sheila McBreen,N. Primak,Sandra Savaglio,A. Yoldas,G. P. Szokoly,S. Klose +9 more
TL;DR: In this article, optical and near-infrared photometry of the afterglow of the long gamma-ray burst (GRB) 070802 at redshift 245 obtained with the ESO/MPI 22 m telescope equipped with the multichannel imager GROND Follow-up observations in g'r'i'z' and JHKS bands started at ~17 minutes and extended up to 28 hr postburst.

Can Neutrino-cooled Accretion Disks Be an Origin of Gamma-Ray Bursts?
Kazunori Kohri,Shin Mineshige +1 more
TL;DR: In this paper, the authors studied the properties of massive accretion tori and found that the luminosity of photons is practically zero, neutrino cooling dominates over advective cooling, pressure of degenerate electrons dominates over the pressure of gas and photons, and magnetic field strength exceeds the critical value of about 4 × 1013 G, even if we take 0.1% of the equipartition value.

Gamma-ray bursts from stellar mass accretion disks around black holes
TL;DR: In this paper, a cosmological model for gamma-ray bursts is explored in which the radiation is produced as a broadly beamed pair fireball along the rotation axis of an accreting black hole.

Spectra and light curves of gamma-ray burst afterglows
TL;DR: In this paper, the broadband spectrum and corresponding light curve of synchrotron radiation from a power-law distribution of electrons in an expanding relativistic shock were calculated for the gamma-ray burst afterglow.

Nucleosynthesis, neutrino bursts and gamma-rays from coalescing neutron stars
David Eichler,David Eichler,Mario Livio,Tsvi Piran,Tsvi Piran,David N. Schramm,David N. Schramm +6 more
TL;DR: In this paper, it was pointed out that neutron-star collisions should synthesize neutron-rich heavy elements, thought to be formed by rapid neutron capture (the r-process), and these collisions should produce neutrino bursts and resultant bursts of gamma rays; the latter should comprise a subclass of observable gamma-ray bursts.
