The Afterglow of GRB 130427A from 1 to 10^16 GHz
D. A. Perley, S. B. Cenko, A. Corsi +31
We present multiwavelength observations of the afterglow of GRB 130427A, the brightest (in total fluence) gamma-ray burst of the past 29 years. Optical spectroscopy from Gemini-Nor…
Evidence for Dust Destruction from the Early-time Colour Change of GRB 120119A
Adam N. Morgan, D. A. Perley, S. B. Cenko +16
We present broadband observations and analysis of Swift gamma-ray burst (GRB) 120119A. Our early-time afterglow detections began under 15 s after the burst in the host frame (redsh…
Discovery of a Cosmological, Relativistic Outburst via its Rapidly Fading Optical Emission
S. Bradley Cenko, S. R. Kulkarni, Assaf Horesh +26
We report the discovery by the Palomar Transient Factory (PTF) of the transient source PTF11agg, which is distinguished by three primary characteristics: (1) bright, rapidly fading…
A Population of Massive, Luminous Galaxies Hosting Heavily Dust-Obscured Gamma-Ray Bursts: Implications for the Use of GRBs as Tracers of Cosmic Star Formation
D. A. Perley, A. J. Levan, N. R. Tanvir +13
We present observations and analysis of the host galaxies of 23 heavily dust-obscured gamma-ray bursts (GRBs) observed by the Swift satellite during the years 2005-2009, representi…
