We propose that gamma-ray bursts are created in the mergers of double neutron star binaries and black hole neutron star binaries at cosmological distances. Two different processes provide the electromagnetic energy for the bursts: neutrino-antineutrino annihilation into electron-position pairs during the merger, and magnetic flares generated by the Parker instability in a postmerger differentially rotating disk. In both cases, an optically thick fireball of size less than or approximately equal…

### Gamma-ray bursts as collimated jets from neutron star/black hole mergers

• Physics
Nature
• 1993
THE distribution of more than 150 γ-ray bursts detected by the BATSE experiment is isotropic on the sky but radially non-uniform1,2. This raises the possibility that bursts are cosmological (at z≲l)

### Magnetically Inspired Explosive Outflows from Neutron-star Mergers

• Physics
The Astrophysical Journal
• 2019
Binary neutron-star mergers have long been associated with short-duration gamma-ray bursts (GRBs). This connection was confirmed with the first coincident detection of gravitational waves together

### Formation Rates of Black Hole Accretion Disk Gamma-Ray Bursts

• Physics
The Astrophysical Journal
• 1999
The cosmological origin of at least an appreciable fraction of classical gamma-ray bursts (GRBs) is now supported by redshift measurements for a half-dozen faint host galaxies. Still, the nature of

### GeV Signatures of Short Gamma-Ray Bursts in Active Galactic Nuclei

• Physics
The Astrophysical Journal
• 2022
The joint detection of gravitational waves and the gamma-ray counterpart of a binary neutron star merger event, GW170817, unambiguously validates the connection between short gamma-ray bursts and

### On the Central Engine of Short Gamma-Ray Bursts

• Physics
• 2003
We assess the ability of neutron star binary coalescence to produce short gamma-ray bursts (GRBs). We find that the neutrino annihilation above the merged remnant will drive bipolar, relativistic

### Gamma-ray bursts and binary neutron star mergers

Neutron star binaries, such as the one observed in the famous binary pulsar PSR 1916+13, end their life in a catastrophic merge event (denoted here NS$^2$M). The merger releases \$\approx 5 \cdot

### The role of the magnetic fields in GRB outflows

• Physics
• 2022
Russia Gamma-ray bursts (GRBs) are bright extragalactic ﬂashes of gamma-ray radiation and brieﬂy the most energetic explosions in the Universe. Their catastrophic origin —the merger of compact

The distribution of γ‐ray bursts as observed by BATSE rules out the galactic disk origin, and it is consistent with the cosmological origin. Much work is currently done to reconcile galactic halo

### Evolution of a neutrino-cooled disc in gamma-ray bursts

• Physics
• 2004
Rapid, hyper-Eddington accretion is likely to power the central engines of gamma-ray bursts (GRBs). In the extreme conditions of densities and temperatures the accreting torus is cooled by neutrino

### The Merger of a Helium Star and a Black Hole: Gamma-Ray Bursts

• Physics
• 2000
There is growing observational evidence that gamma-ray bursts (GRBs) are powered by black holes accreting rapidly through a disk. The supernova-like outburst that accompanies some gamma-ray bursts
