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 high redshift (z ≈ 1) and found in subluminous star-forming host galaxies. They are likely to be produced in core-collapse explosions of massive stars. In contrast, no short GRB had been accurately (< 10″) and rapidly (minutes) located. Here we report the detection of the X-ray afterglow from—and the… 

Discovery of the short γ-ray burst GRB 050709

Gamma-ray bursts (GRBs) fall into two classes: short-hard and long-soft bursts. The latter are now known to have X-ray and optical afterglows, to occur at cosmological distances in star-forming

An origin for short γ-ray bursts unassociated with current star formation

Two short (< 2 s) γ-ray bursts (GRBs) have recently been localized and fading afterglow counterparts detected. The combination of these two results left unclear the nature of the host galaxies of the

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

An origin in the local Universe for some short γ-ray bursts

Gamma-ray bursts (GRBs) divide into two classes: ‘long’, which typically have initial durations of T90 > 2 s, and ‘short’, with durations of T90 < 2 s (where T90 is the time to detect 90% of the

GRB 060121: implications of a short-/intermediate-duration γ-ray burst at high redshift

Since the discovery of the first short-population γ-ray burst (GRB) afterglows in 2005, the handful of observed events have been found to be embedded in nearby (z < 1), bright underlying galaxies. We

Short-Duration Gamma-Ray Bursts

Gamma-ray bursts (GRBs) display a bimodal duration distribution with a separation between the short- and long-duration bursts at about 2 s. The progenitors of long GRBs have been identified as

THE LUMINOUS INFRARED HOST GALAXY OF SHORT-DURATION GRB 100206A

The known host galaxies of short-hard gamma-ray bursts (GRBs) to date are characterized by low to moderate star formation rates (SFRs) and a broad range of stellar masses, in general agreement with

Optical emission from GRB 050709 : a short/hard GRB in a star-forming galaxy

TLDR
Optical observations of the short/hard gamma-ray burst GRB 050709 are presented, the first such event with an identified optical counterpart, and it is shown that at least some short GRBs originate in a young population.

Most Short-Hard Gamma-Ray Bursts Are Not in Moderately Bright Nearby Host Galaxies

The recent discovery by the Swift and HETE-2 satellites of X-ray afterglows from five short-hard bursts (SHBs) has lead to a simple picture in which SHBs have a typical isotropic burst energy of

Gamma-ray bursts in the Swift era

Gamma-ray burst (GRB) research has undergone a revolution in the last two years. The launch of Swift, with its rapid slewing capability, has greatly increased the number and quality of GRB

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

Soft-γ-ray repeaters (SGRs) are galactic X-ray stars that emit numerous short-duration (about 0.1 s) bursts of hard X-rays during sporadic active periods. They are thought to be magnetars: strongly

If the efficiency for producing gamma rays is the same in short-duration (≲2 s) gamma-ray bursts (GRBs) as in long-duration GRBs, then the average kinetic energy per solid angle in short GRBs must be

TLDR
The detection of a long giant flare from SGR 1806-20, which was much more luminous than any previous transient event observed in the authors' Galaxy, and at least a significant fraction of the mysterious short-duration gamma-ray bursts may come from extragalactic magnetars.
