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 localizations and x-ray and optical afterglow lightcurves. Over 160 GRBs have been detected, and nearly all have been followed up with the on-board narrow field telescopes. Advances in our understanding of short GRBs have been spectacular. The detection of x-ray afterglows has led to accurate localizations…

The detection of X-ray afterglows has led to accurate localizations and the conclusion that short GRBs can occur in non-star-forming galaxies or regions, whereas long GRBs are strongly concentrated within the star-forming regions.

Standardized Long Gamma-Ray Bursts as a Cosmic Distance Indicator

Gamma-ray bursts (GRBs) are the most luminous explosions in and can be detectable out to the edge of the universe. They have long been thought to be able to extend the Hubble diagram to very high

A Short Gamma-Ray Burst from a Protomagnetar Remnant

The contemporaneous detection of gravitational waves and gamma rays from GW170817/GRB 170817A, followed by kilonova emission a day after, confirmed compact binary neutron star mergers as progenitors

Very Early Optical Afterglows of Gamma-Ray Bursts: Evidence for Relative Paucity of Detection

Comparisons of the X-ray afterglow flux to the optical after glow flux and prompt γ-ray fluence is used to quantify the seemingly deficient optical, and in some cases X-rays, light at these early epochs.

Observation of inverse Compton emission from a long γ-ray burst

A multi-frequency observing campaign of the γ-ray burst GRB 190114C reveals a broadband double-peaked spectral energy distribution, and the teraelectronvolt emission could be attributed to inverse Compton scattering.

Short GRB 160821B: A Reverse Shock, a Refreshed Shock, and a Well-sampled Kilonova

We report our identification of the optical afterglow and host galaxy of the short-duration gamma-ray burst sGRB 160821B. The spectroscopic redshift of the host is z = 0.162, making it one of the

Probing the low-luminosity gamma-ray burst population with new generation satellite detectors

We compare the detection rates and redshift distributions of low-luminosity (LL) gamma-ray bursts (GRBs) localized by Swift with those expected to be observed by the new generation satellite

The detection of GW170817, it’s extensive multi-wavelength follow-up campaign, and the large amount of theoretical development and interpretation that followed, have resulted in a significant step



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

The radio afterglow from the γ-ray burst of 8 May 1997

Important insight into the nature of γ-ray bursts (GRBs) has been gained in recent months mainly due to the immediate, precise localization of the bursts and the discovery of relatively long-lived

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

The Swift Gamma-Ray Burst Mission

The Swift mission will determine the origin of GRB, classify GRBs and search for new types, study the interaction of the ultrarelativistic outflows of GRBs with their surrounding medium, and use GRBs to study the early universe out to z >10.

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

Gamma-Ray Burst Energetics in the Swift Era

We examine the rest-frame energetics of 76 gamma-ray bursts (GRBs) with known redshift that were detected by the Swift spacecraft and monitored by the satellite’s X-Ray Telescope (XRT). Using the

The afterglow of GRB 050709 and the nature of the short-hard γ-ray bursts

The final chapter in the long-standing mystery of the γ-ray bursts (GRBs) centres on the origin of the short-hard class of bursts, which are suspected on theoretical grounds to result from the

The Early X-Ray Emission from GRBs

Observations of the early X-ray emission for a sample of 40 gamma-ray bursts obtained using the Swift satellite, for which the narrow-field instruments were pointed at the burst within 10 minutes of the trigger, show that theX-ray light curve can be well described by an exponential that relaxes into a power law.

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

The optical afterglow of the short γ-ray burst GRB 050709

It has long been known that there are two classes of γ-ray bursts (GRBs), mainly distinguished by their durations. The breakthrough in our understanding of long-duration GRBs (those lasting more than
