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…
Gemini Spectroscopy of the Short GRB 130603B Afterglow and Host
A. Cucchiara, J. X. Prochaska, D. A. Perley +5
We present early optical photometry and spectroscopy of the afterglow and host galaxy of the bright short-duration gamma-ray burst GRB 130603B discovered by the Swift satellite. Us…
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…
