On the nature of the 'hostless' short GRBs
R. L. Tunnicliffe, A. J. Levan, N. R. Tanvir +12
A significant proportion () of the short-duration gamma-ray bursts (SGRBs) localised by Swift have no detected host galaxy coincident with the burst location to deep limi…
A "kilonova" associated with short-duration gamma-ray burst 130603B
N. R. Tanvir, A. J. Levan, A. S. Fruchter +4
Short-duration gamma-ray bursts (SGRBs) are intense flashes of cosmic gamma-rays, lasting less than ~2 s, whose origin is one of the great unsolved questions of astrophysics today.…
Demographics of the Galaxies Hosting Short-duration Gamma-Ray Bursts
Wen-fai Fong, Edo Berger, Ryan Chornock +17
We present observations of the afterglows and host galaxies of three short-duration gamma-ray bursts (GRBs): 100625A, 101219A and 110112A. We find that GRB 100625A occurred in a z=…
A new population of ultra-long duration gamma-ray bursts
A. J. Levan, N. R. Tanvir, R. L. C. Starling +38
We present comprehensive multiwavelength observations of three gamma-ray bursts (GRBs) with durations of several thousand seconds. We demonstrate that these events are extragalacti…
The Afterglow and ULIRG Host Galaxy of the Dark Short GRB 120804A
E. Berger, B. A. Zauderer, A. Levan +12
We present the optical discovery and sub-arcsecond optical and X-ray localization of the afterglow of the short GRB 120804A, as well as optical, near-IR, and radio detections of it…
An extremely luminous panchromatic outburst from the nucleus of a distant galaxy
A. J. Levan, N. R. Tanvir, S. B. Cenko +58
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major…
