Supermassive Objects as Gamma-Ray Bursters [PDF]

The Astrophysical Journal, 1998
We propose that the gravitational collapse of supermassive objects ($ M\ga 10^4 M_\odot$), either as relativistic star clusters or as single supermassive stars (which may result from stellar mergers in dense star clusters), could be a cosmological source of $ $-ray bursts.

THE NUMERICAL THREE-DIMENSIONAL HYDRODYNAMIC SIMULATION OF THE γ-RAY BURSTERS AND X-RAY BURSTERS

Odessa Astronomical Publications, 2013
An radiative wind accretion on to the compact object in a detached close binary system (CBS) where one of the components is a supergiant with radiation stellar wind that blows from its surface, and another component is a compact object (black hole or ...

Matter-affected neutrino oscillations in ordinary and mirror stars and their implications for gamma-ray bursts [PDF]

, 1999
It has been proposed that the annihilation process $\nu\bar{\nu} \to e^{-}e^{+} \to \gamma\gamma$ may be responsible for the generation of gamma-ray bursts (GRBs).

Gamma-ray burster counterparts - Infrared

The Astrophysical Journal, 1987
The discovery of an IR counterpart to a gamma-ray burster (GRB) would be a big step forward in understanding this enigmatic phenomenon. A program of searching for IR emission from the smallest GRB source regions has been initiated. Seven boxes have been searched with ground-based telescopes at a wavelength of 2.2 microns and 23 with the IRAS data base ...

Gamma ray bursters and black holes in gravity’s rainbow

International Journal of Geometric Methods in Modern Physics, 2023
In this paper, we analyze the modification to the thermodynamics of a Schwarzschild black hole and a Kerr black hole due to gravity’s rainbow. The metric for these black holes will be made energy dependent. This will be done by using rainbow functions motivated from the hard spectra from gamma-ray bursters at cosmological distances.

Theory of Gamma Ray Bursters [PDF]

Symposium - International Astronomical Union, 1987
Gamma ray bursters are interpreted as nuclear explosions under the surface of neutron stars. The explosions occur after transportation of the matter with nonequilibrium composition during starquakes in outer layers where the matter becomes unstable and explodes as a result of a developing chain reaction.

Gamma-ray burster recurrence time scales [PDF]

The Astrophysical Journal, 1985
In the decade since gamma-ray bursters (GRBs) were discovered by Klebesadel et al. (1973), many models have been proposed to explain the GRB phenomenon. A difficulty is related to the small number of predictions which would make it possible to evaluate the models. One verifiable prediction is the recurrence time scale, tau-gamma.

Gamma-ray burster counterparts - Radio

The Astrophysical Journal, 1989
Many observers and theorists have suggested that gamma-ray bursters (GRBs) are related to highly magnetized rotating, neutron stars, in which case an analogy with pulsars implies that GRBs would be prodigious emitters of polarized radio emission during quiescence.

A perspective on Quantum Gravity Phenomenology [PDF]

, 2003
I give a brief overview of some Quantum-Gravity-Phenomenology research lines, focusing on studies of cosmic rays and gamma-ray bursts that concern the fate of Lorentz symmetry in quantum spacetime.
