Short gamma-ray bursts (SGRBs) observed by Swift potentially reveal the first insight into cataclysmic compact object mergers. To ultimately acquire a fundamental understanding of these events requires pan-spectral observations and knowledge of their spatial distribution to differentiate between proposed progenitor populations. Up to 2012 April, there are only some 30 per cent of SGRBs with reasonably firm redshifts, and this sample is highly biased by the limited sensitivity of Swift to detect…

The Swift short gamma-ray burst rate density: prospects for detecting binary neutron star mergers by aLIGO
Presently only 30% of short gamma ray bursts (SGRBs) have accurate redshifts, and this sample is highly biased by the limited sensitivity of {\it Swift} to detect SGRBs. We account for the dominant
Recent observational and theoretical results suggest that short-duration gamma-ray bursts (SGRBs) originate from the merger of compact binary systems of two neutron stars or a neutron star and a
Binary neutron star merger rate via the luminosity function of short gamma-ray bursts
The luminosity function of short Gamma Ray Bursts (GRBs) is modelled by using the available catalogue data of all short GRBs (sGRBs) detected till October, 2017. The luminosities are estimated via
Interpreting Short Gamma Ray Burst Progenitor Kicks and Time Delays Using the Host Galaxy-Dark Matter Halo Connection
Nearly 20% of short gamma-ray bursts (sGRBs) have no observed host galaxies. Combining this finding with constraints on galaxies' dark matter halo potential wells gives strong limits on the natal
Revisiting the event rate of short GRBs and estimating their detectable number within the Advanced LIGO horizon
The redshift and luminosity distributions of 36 Swift short GRBs are fitted by connecting their event rates with cosmic star formation rates by power-law distributed delayed times f(τ) ∝ τ, where a
Linking the rates of neutron star binaries and short gamma-ray bursts
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
Viewing Short Gamma-Ray Bursts From a Different Angle
The detection of a faint, short gamma-ray burst (GRB 170817A) in coincidence with the gravitational wave (GW 170817) detection by LIGO/Virgo is at odds with the expected known luminosity and redshift
We use realistic Monte Carlo simulations including both gravitational-wave (GW) and short gamma-ray burst (sGRB) selection effects to revisit the coincident rate of binary systems composed of two
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.
Fast Radio Bursts with Extended Gamma-Ray Emission?
We consider some general implications of bright gamma-ray counterparts to fast radio bursts (FRBs). We show that even if these manifest in only a fraction of FRBs, gamma-ray detections with current


Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves,
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
GRB 080503: implications of a naked short gamma-ray burst dominated by extended emission
We report on observations of GRB 080503, a short gamma-ray burst (GRB) with very bright extended emission (about 30 times the gamma-ray fluence of the initial spike) in conjunction with a thorough
A Compact Binary Merger Model for the Short, Hard GRB 050509b
The first X-ray afterglow for a short ({approx}30ms), hard {gamma}-ray burst was detected by Swift on 9 May 2005 (GRB 050509b). No optical or radio counterpart was identified in follow-up
Where are the missing gamma-ray burst redshifts?
In the redshift range z = 0‐1, the gamma-ray burst (GRB) redshift distribution should increase rapidly because of increasing differential volume sizes and strong evolution in the star formation rate
A short γ-ray burst apparently associated with an elliptical galaxy at redshift z = 0.225
Gamma-ray bursts (GRBs) come in two classes: long (> 2 s), soft-spectrum bursts and short, hard events. Most progress has been made on understanding the long GRBs, which are typically observed at
A Putative Early-Type Host Galaxy for GRB 060502B: Implications for the Progenitors of Short-Duration Hard-Spectrum Bursts
Starting with the first detection of an afterglow from a short-duration hard-spectrum γ-ray burst (SHB) by Swift last year, a growing body of evidence has suggested that SHBs are associated with an
The BATSE-Swift luminosity and redshift distributions of short-duration GRBs
We compare the luminosity function and rate inferred from the BATSE peak flux distribution of short hard bursts (SHBs) with the redshift and luminosity distributions of SHBs observed by Swift /HETE
The afterglow and elliptical host galaxy of the short γ-ray burst GRB 050724
Despite a rich phenomenology, γ-ray bursts (GRBs) are divided into two classes based on their duration and spectral hardness—the long-soft and the short-hard bursts. The discovery of afterglow
X-ray continuum properties of GRB afterglows observed by XMM-Newton and Chandra
We present a catalog of XMM-Newton and Chandra observations of gamma-ray burst (GRB) afterglows, reduced in a common way using the most up-to-date calibration files and software. We focus on the
