Prompt optical observations of GRB050319 with the Swift UVOT
K. O. Mason, A. J. Blustin, P. Boyd +18
The UVOT telescope on the Swift observatory has detected optical afterglow emission from GRB 050319. The flux declines with a power law slope of alpha = -0.57 between the start of…
Very Early Optical Afterglows of Gamma-Ray Bursts: Evidence for Relative Paucity of Detection
P. W. A. Roming, P. Schady, D. B. Fox +38
Very early observations with the Swift satellite of gamma-ray burst (GRB) afterglows reveal that the optical component is not detected in a large number of cases. This is in contra…
The Swift Ultra-Violet/Optical Telescope
P. W. A. Roming, T. E. Kennedy, K. O. Mason +22
The UV/Optical Telescope (UVOT) is one of three instruments flying aboard the Swift Gamma-ray Observatory. It is designed to capture the early (approximately 1 minute) UV and optic…
Prompt and afterglow early X-ray phases in the comoving frame. Evidence for Universal properties?
G. Chincarini, A. Moretti, P. Romano +38
We analyze the Swift XRT light curves and spectra of the gamma-ray bursts (GRBs) for which the redshift has been measured. The sample consists of seven GRBs. The soft X-ray light c…
Ultraviolet, Optical, and X-Ray Observations of the Type Ia Supernova 2005am with Swift
P. J. Brown, S. T. Holland, C. James +21
We present ultraviolet and optical light curves in six broadband filters and grism spectra obtained by Swift's Ultraviolet/Optical Telescope for the Type Ia supernova SN2005am. The…
A short gamma-ray burst apparently asssociated with an elliptical galaxy at redshift z=0.225
N. Gehrels
Gamma Ray Bursts (GRBs) are bright, brief flashes of high energy photons that have fascinated scientists for 30 years. They come in two classes: long (>2 s), softspectrum bursts an…
