We present a detailed broadband afterglow study of GRB 220101A ( s) combining multi-wavelength data from soft X-rays until 6 GHz. The afterglow light cu…
The Broad-band Counterpart of the Short GRB 200522A at : A Luminous Kilonova or a Collimated Outflow with a Reverse Shock?
W. Fong, T. Laskar, J. Rastinejad +20
We present the discovery of the radio afterglow and near-infrared (NIR) counterpart of the Swift short GRB 200522A, located at a small projected offset of kpc from the…
Discovery of the optical afterglow and host galaxy of short GRB181123B at : Implications for Delay Time Distributions
K. Paterson, W. Fong, A. Nugent +19
We present the discovery of the optical afterglow and host galaxy of the {\it Swift} short-duration gamma-ray burst, GRB\,181123B. Observations with Gemini-North starting at $\appr…
The Case for a High-Redshift Origin of GRB100205A
A. A. Chrimes, A. J. Levan, E. R. Stanway +15
The number of long gamma-ray bursts (GRBs) known to have occurred in the distant Universe (z greater than 5) is small (approx 15), however these events provide a powerful way of pr…
GRB 120422A/SN 2012bz: Bridging the Gap between Low- And High-Luminosity GRBs
S. Schulze, D. Malesani, A. Cucchiara +62
At low redshift, a handful of gamma-ray bursts (GRBs) have been discovered with peak luminosities () substantially lower than the average…
New constraints on GRB jet geometry and relativistic shock physics
C. Guidorzi, C. G. Mundell, R. Harrison +23
We use high--quality, multi-band observations of Swift GRB120404A, from gamma-ray to radio frequencies, together with the new hydrodynamics code of van Eerten et al. (2012) to test…
GRB 091024A and the nature of ultra-long gamma-ray bursts
F. J. Virgili, C. G. Mundell, V. Pal'shin +30
We present a broadband study of gamma-ray burst (GRB) 091024A within the context of other ultra-long-duration GRBs. An unusually long burst detected by Konus-Wind, Swift, and Fermi…
GRB 120521C at z~6 and the Properties of High-redshift GRBs
T. Laskar, E. Berger, N. Tanvir +9
We present optical, near-infrared, and radio observations of the afterglow of GRB 120521C. By modeling the multi-wavelength dataset, we derive a photometric redshift of z~6.0, whic…
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 Spectroscopic Classification and Explosion Properties of SN2009nz Associated with GRB091127 at z=0.490
E. Berger, R. Chornock, T. R. Holmes +6
We present spectroscopic observations of GRB091127 (z=0.490) at the peak of the putative associated supernova, SN2009nz. Subtracting a late-time spectrum of the host galaxy, we iso…
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…
PTF10iya: A short-lived, luminous flare from the nuclear region of a star-forming galaxy
S. Bradley Cenko, Joshua S. Bloom, S. R. Kulkarni +28
We present the discovery and characterisation of PTF10iya, a short-lived (dt ~ 10 d, with an optical decay rate of ~ 0.3 mag per d), luminous (M_g ~ -21 mag) transient source found…
The unusual X-ray emission of the short Swift GRB 090515: Evidence for the formation of a magnetar?
A. Rowlinson, P. T. O'Brien, N. R. Tanvir +16
The majority of short gamma-ray bursts (SGRBs) are thought to originate from the merger of compact binary systems collapsing directly to form a black hole. However, it has been pro…
Challenging GRB models through the broadband dataset of GRB060908
S. Covino, S. Campana, M. L. Conciatore +37
Context: Multiwavelength observations of gamma-ray burst prompt and afterglow emission are a key tool to disentangle the various possible emission processes and scenarios proposed…
