Jet breaks and Energetics of Swift GRB X-ray Afterglows
J. L. Racusin, E. W. Liang, D. N. Burrows +6
We present a systematic temporal and spectral study of all Swift-XRT observations of GRB afterglows discovered between 2005 January and 2007 December. After constructing and fittin…
Late time observations of GRB080319B: jet break, host galaxy and accompanying supernova
Nial R. Tanvir, Evert Rol, Andrew Levan +15
The Swift discovered GRB080319B was by far the most distant source ever observed at naked eye brightness, reaching a peak apparent magnitude of 5.3 at a redshift of z=0.937. We pre…
The First Swift Ultra-Violet/Optical Telescope GRB Afterglow Catalog
P. W. A. Roming, T. S. Koch, S. R. Oates +21
We present the first Swift Ultra-Violet/Optical Telescope (UVOT) gamma-ray burst (GRB) afterglow catalog. The catalog contains data from over 64,000 independent UVOT image observat…
Correlations of Prompt and Afterglow Emission in Swift Long and Short Gamma Ray Bursts
N. Gehrels, S. D. Barthelmy, D. N. Burrows +12
Correlation studies of prompt and afterglow emissions from gamma-ray bursts (GRBs) between different spectral bands has been difficult to do in the past because few bursts had comp…
The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125
Adria C. Updike, Joshua B. Haislip, Melissa C. Nysewander +52
We report on multi-wavelength observations, ranging from the X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the prese…
Observations of X-ray Flares from Gamma Ray Bursts
A. D. Falcone, D. Morris, J. Racusin +11
Swift-XRT observations of the X-ray emission from gamma ray bursts (GRBs) and during the GRB afterglow have led to many new results during the past two years. One of these exciting…
