X-ray flares following short gamma-ray bursts from shock heating of binary stellar companions
Andrew I. MacFadyen, Enrico Ramirez-Ruiz, Weiqun Zhang
The discovery of long-lasting (~100 s) X-ray flares following short gamma-ray bursts initially called into question whether they were truly classical short-hard bursts. Opinion ove…
The Galaxy Hosts and Large-Scale Environments of Short-Hard Gamma-Ray Bursts
J. X. Prochaska, J. S. Bloom, H. -W. Chen +8
The rapid succession of discovery of short--duration hard--spectrum GRBs has led to unprecedented insights into the energetics of the explosion and nature of the progenitors. Yet s…
Photospheric signatures imprinted on the gamma-ray burst spectra
Enrico Ramirez-Ruiz
A solution is presented for the spectrum of high-energy gamma-ray burst photons confined to a quasi-thermal baryonic photosphere. The solution is valid in the steady-state limit as…
Accretion modes in collapsars - prospects for GRB production
William H. Lee, Enrico Ramirez-Ruiz
We explore low angular momentum accretion flows onto black holes formed after the collapse of massive stellar cores. In particular, we consider the state of the gas falling quasi-s…
Evidence for a Canonical GRB Afterglow Light Curve in the Swift/XRT Data
J. A. Nousek, C. Kouveliotou, D. Grupe +25
We present new observations of the early X-ray afterglows of the first 27 gamma-ray bursts (GRBs) detected with the Swift X-ray Telescope (XRT). The early X-ray afterglows show a c…
GRB 050509B: Constraints on short gamma-ray burst models
J. Hjorth, J. Sollerman, J. Gorosabel +19
We have obtained deep optical images with the Very Large Telescope at ESO of the first well-localized short-duration gamma-ray burst, GRB 050509B. From V and R imaging, initiated ~…
