Swift-UVOT captures the earliest ultraviolet spectrum of a Gamma Ray Burst
N. P. M. Kuin, W. B. Landsman, M. J. Page +22
We present the earliest ever ultraviolet spectrum of a gamma-ray burst (GRB) as observed with the Swift-UVOT. The GRB 081203A spectrum was observed for 50 seconds with the UV grism…
Testing the Possible Intrinsic Origin of the Excess of Very Strong MgII Absorbers Along GRB Lines-of-Sight
A. Cucchiara, T. Jones, J. C. Charlton +3
The startling discovery of Prochter et al. (2006) that the frequency of very strong (W_r(2796)>1 A) MgII absorbers along gamma-ray burst (GRB) lines of sight ([dN/dz]_{GRB} = 0.90)…
GRB 080319B: A Naked-Eye Stellar Blast from the Distant Universe
J. L. Racusin, S. V. Karpov, M. Sokolowski +81
Long duration gamma-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation…
The complex light-curve of the afterglow of GRB071010A
S. Covino, P. D'Avanzo, A. Klotz +51
We present and discuss the results of an extensive observational campaign devoted to GRB071010A, a long-duration gamma-ray burst detected by the Swift satellite. This event was fol…
GRBs 070429B and 070714B: The High End of the Short-Duration Gamma-Ray Burst Redshift Distribution
S. Bradley Cenko, Edo Berger, Ehud Nakar +11
We present optical spectra of the host galaxies of the short-duration gamma-ray burst GRB 070429B and the likely short-duration with extended emission GRB 070714B. In both cases, w…
An extremely luminous X-ray outburst at the birth of a supernova
A. M. Soderberg, E. Berger, K. L. Page +40
Massive stars end their short lives in spectacular explosions, supernovae, that synthesize new elements and drive galaxy evolution. Throughout history supernovae were discovered ch…
GRB070125: The First Long-Duration Gamma-Ray Burst in a Halo Environment
S. B. Cenko, D. B. Fox, B. E. Penprase +15
We present the discovery and high signal-to-noise spectroscopic observations of the optical afterglow of the long-duration gamma-ray burst GRB070125. Unlike all previously observed…
Properties of a Gamma Ray Burst Host Galaxy at z ~ 5
P. A. Price, A. Songaila, L. L. Cowie +9
We describe the properties of the host galaxy of the gamma-ray burst GRB060510B based on a spectrum of the burst afterglow obtained with the Gemini North 8m telescope. The galaxy l…
A New Population of High Redshift Short-Duration Gamma-Ray Bursts
E. Berger, D. B. Fox, P. A. Price +23
The redshift distribution of the short-duration GRBs is a crucial, but currently fragmentary, clue to the nature of their progenitors. Here we present optical observations of nine…
Discovery of an Extreme MeV Blazar with the Swift Burst Alert Telescope
Rita M. Sambruna
The Burst Alert Telescope (BAT) onboard Swift detected bright emission from 15--195 keV from the source SWIFT~J0746.3+2548 (J0746 in the following), identified with the optically-f…
Swift panchromatic observations of the bright gamma-ray burst GRB050525a
A. J. Blustin, D. Band, S. Barthelmy +12
The bright gamma-ray burst GRB050525a has been detected with the Swift observatory, providing unique multiwavelength coverage from the very earliest phases of the burst. The X-ray…
SN 2003lw and GRB 031203: A Bright Supernova for a Faint Gamma-ray Burst
D. Malesani, G. Tagliaferri, G. Chincarini +23
Optical and near-infrared observations of the gamma-ray burst GRB 031203, at z = 0.1055, are reported. A very faint afterglow is detected superimposed to the host galaxy in our fir…
