Short Gamma Ray Bursts as possible electromagnetic counterpart of coalescing binary systems [PDF]

, 2010
Coalescing binary systems, consisting of two collapsed objects, are among the most promising sources of high frequency gravitational waves signals detectable, in principle, by ground-based interferometers.

Model Constraints Based on the IceCube Neutrino Nondetection of GRB 221009A

The Astrophysical Journal, 2023
GRB 221009A is a bright gamma-ray burst (GRB) with isotropic energy larger than 10 ^54 erg. Its fairly low redshift makes it a promising candidate for high-energy neutrino detection.

Repeating Emission Episodes in Gamma-Ray Bursts: Millilensing or Jet Precession?

The Astrophysical Journal, 2023
Recently, some gamma-ray bursts (GRBs) whose light curves consist of repeating emission episodes with similar temporal profiles have attracted extensive attention.

Black Hole Accretion in Gamma Ray Bursts

Galaxies, 2017
We study the structure and evolution of the hyperaccreting disks and outflows in the gamma ray bursts central engines. The torus around a stellar mass black hole is composed of free nucleons, Helium, electron-positron pairs, and is cooled by neutrino ...

GRB 221009A with an Unconventional Precursor: A Typical Two-stage Collapsar Scenario?

The Astrophysical Journal, 2023
As the brightest gamma-ray burst (GRB) ever detected, GRB 221009A may offer a chance that reveals some interesting features that are hidden in those bursts that are not so bright.

SHORT GAMMA-RAY BURSTS FROM THE MERGER OF TWO BLACK HOLES [PDF]

, 2016
Short gamma-ray bursts (GRBs) are explosions of cosmic origins believed to be associated with the merger of two compact objects, either two neutron stars or a neutron star and a black hole (BH).

The Diversity of Kilonova Emission in Short Gamma-Ray Bursts [PDF]

Astrophysical Journal, 2017
The historic first joint detection of both gravitational-wave and electromagnetic emission from a binary neutron star merger cemented the association between short gamma-ray bursts (SGRBs) and compact object mergers, as well as providing a well-sampled ...

Collapsars: Gamma-Ray Bursts and Explosions in “Failed Supernovae” [PDF]

, 1998
Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα ≳ 10 M☉, in which iron-core collapse does not produce a successful outgoing shock but instead forms a black hole of 2-3 M☉. The model

MERGERS OF CHARGED BLACK HOLES: GRAVITATIONAL-WAVE EVENTS, SHORT GAMMA-RAY BURSTS, AND FAST RADIO BURSTS [PDF]

, 2016
The discoveries of GW150914, GW151226, and LVT151012 suggest that double black hole (BH–BH) mergers are common in the universe. If at least one of the two merging black holes (BHs) carries a certain amount of charge, possibly retained by a rotating ...
