Short gamma-ray bursts are believed to be produced by both binary neutron star (BNS) and neutron star-black hole (NSBH) mergers. We use current estimates for the BNS and NSBH merger rates to calculate the fraction of observable short gamma-ray bursts produced through each channel. This allows us to constrain merger rates of BNS to R BNS = 384 +431 − 213 Gpc − 3 yr − 1 (90% credible interval), a 16% decrease in the rate uncertainties from the second LIGO–Virgo Gravitational-Wave Transient…

Constraints On Short, Hard Gamma-Ray Burst Beaming Angles From Gravitational Wave Observations
The first detection of a binary neutron star merger, GW170817, and an associated short gamma-ray burst confirmed that neutron star mergers are responsible for at least some of these bursts. The
A Search for Neutron Star–Black Hole Binary Mergers in the Short Gamma-Ray Burst Population
Short gamma-ray bursts (SGRBs) are now known to be the product of the merger of two compact objects. However, two possible formation channels exist: neutron star -- neutron star (NS -- NS) or NS --
Gamma-ray bursts as the death throes of massive binary stars
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
The Properties of Short gamma-ray burst Jets Triggered by neutron star mergers
The most popular model for short gamma-ray bursts (sGRBs) involves the coalescence of binary neutron stars. Because the progenitor is actually hidden from view, we must consider under which
Gamma-ray bursts as collimated jets from neutron star/black hole mergers
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)
Mergers of black hole–neutron star binaries and rates of associated electromagnetic counterparts
Black hole-neutron star (BHNS) binaries are amongst promising candidates for the joint detection of electromagnetic (EM) signals with gravitational waves (GWs) and are expected to be detected in the
A lesson from GW170817: most neutron star mergers result in tightly collimated successful GRB jets
The joint detection of gravitational waves (GWs) and $\gamma$-rays from a binary neutron-star (NS) merger provided a unique view of off-axis GRBs and an independent measurement of the NS merger rate.
Black Hole-Neutron Star Mergers as Central Engines of Gamma-Ray Bursts.
Hydrodynamic simulations of the merger of stellar mass black hole-neutron star binaries are compared with mergers of binary neutron stars and the use of a physical nuclear equation of state allows us to include the effects of neutrino emission.
Counting on Short Gamma-Ray Bursts: Gravitational-wave Constraints of Jet Geometry
The detection of GW170817 in gravitational waves and gamma rays revealed that short gamma-ray bursts are associated with the merger of neutron-stars. Gamma rays are thought to result from the
Nucleosynthesis, neutrino bursts and γ-rays from coalescing neutron stars
NEUTRON-STAR collisions occur inevitably when binary neutron stars spiral into each other as a result of damping of gravitational radiation. Such collisions will produce a characteristic burst of
