Spectroscopy of the short-hard GRB 130603B: The host galaxy and environment of a compact object merger

A. de Ugarte Postigo, C. C. Thoene, A. Rowlinson +40

Short duration gamma-ray bursts (SGRBs) are thought to be related to the violent merger of compact objects, such as neutron stars or black holes, which makes them promising sources…

The properties of the 2175AA extinction feature discovered in GRB afterglows

Tayyaba Zafar, Darach Watson, Ardis Eliasdottir +10

The unequivocal, spectroscopic detection of the 2175 bump in extinction curves outside the Local Group is rare. To date, the properties of the bump have been examined in only two G…

Pre-ALMA observations of GRBs in the mm/submm range

A. de Ugarte Postigo, A. Lundgren, S. Martín +24

GRBs generate an afterglow emission that can be detected from radio to X-rays during days, or even weeks after the initial explosion. The peak of this emission crosses the mm/submm…

Searching for differences in Swift's intermediate GRBs

A. de Ugarte Postigo, I. Horváth, P. Veres +16

Gamma-ray bursts are usually classified through their high-energy emission into short-duration and long-duration bursts, which presumably reflect two different types of progenitors…

Limits on Radioactive-Powered Emission Associated With a Short-Hard GRB 070724A in a Star-Forming Galaxy

Daniel Kocevski, Christina C Thone, Enrico Ramirez-Ruiz +10

We present results of an extensive observing campaign of the short duration, hard spectrum gamma-ray burst (GRB) 070724A, aimed at detecting the radioactively-powered emission that…

Low-Resolution Spectroscopy of Gamma-ray Burst Optical Afterglows: Biases in the Swift Sample and Characterization of the Absorbers

J. P. U. Fynbo, P. Jakobsson, J. X. Prochaska +39

(Abridged). We present a sample of 77 optical afterglows (OAs) of Swift detected GRBs for which spectroscopic follow-up observations have been secured. We provide linelists and equ…
