Multiwavelength analysis of the intriguing GRB 061126: the reverse shock scenario and magnetization
A. Gomboc, S. Kobayashi, C. Guidorzi +30
We present a detailed study of the prompt and afterglow emission from Swift GRB 061126 using BAT, XRT, UVOT data and multi-color optical imaging from ten ground-based telescopes. G…
GRB 050826: A Subluminous Event at z = 0.296 Finds its Place in the Luminosity Distribution of Gamma-Ray Burst Afterglows
N. Mirabal, J. P. Halpern, P. T. O'Brien
We present the optical identification and spectroscopy of the host galaxy of GRB 050826 at a redshift z = 0.296 +/- 0.001. Image subtraction among observations obtained on three co…
GRB Radiative Efficiencies Derived from the Swift Data: GRBs vs. XRFs, Long vs. Short
Bing Zhang, Enwei Liang, Kim L. Page +17
We systematically analyze the prompt emission and the early afterglow data of a sample of 31 GRBs detected by {\em Swift} before September 2005, and estimate the GRB radiative effi…
The dust-scattered X-ray halo around Swift GRB 050724
S. Vaughan, R. Willingale, P. Romano +12
This paper discusses the X-ray halo around the Swift gamma-ray burst GRB 050724 (z=0.258), detected by the Swift X-Ray Telescope. The halo, which forms a ring around the fading X-r…
Low-resolution VLT spectroscopy of GRBs 991216, 011211 and 021211
P. M. Vreeswijk, A. Smette, A. S. Fruchter +16
We present low-resolution VLT spectroscopy of the afterglow of the gamma-ray bursts (GRBs) 991216, 011211 and 021211. Our spectrum of GRB991216 is the only optical spectrum for thi…
Swift XRT Observations of the Afterglow of GRB 050319
G. Cusumano, V. Mangano, L. Angelini +27
Swift discovered the high redshift GRB 050319 with the Burst Alert Telescope and began observing with its narrow field instruments only 225 s after the burst onset. The afterglow X…
