Suzaku Observations of Four Heavily Absorbed HMXBs
D. C. Morris, R. K. Smith, C. B. Markwardt +4
We report on Suzaku observations of four unidentified sources from the INTEGRAL and Swift BAT Galactic plane surveys. All the sources have a large neutral hydrogen column density a…
Swift X-ray Afterglows and the Missing Jet Break Problem
J. L. Racusin, E. -W. Liang, D. N. Burrows +3
We present a systematic survey of the temporal and spectral properties of all GRB X-ray afterglows observed by Swift-XRT between January 2005 and July 2007. We have constructed a c…
The First Survey of X-ray Flares from Gamma Ray Bursts Observed by Swift: Spectral Properties and Energetics
A. D. Falcone, D. Morris, J. Racusin +12
Observations of gamma ray bursts (GRBs) with Swift produced the initially surprising result that many bursts have large X-ray flares superimposed on the underlying afterglow. The f…
An online repository of Swift/XRT light curves of GRBs
P. A. Evans, A. P. Beardmore, K. L. Page +12
Context. Swift data are revolutionising our understanding of Gamma Ray Bursts. Since bursts fade rapidly, it is desirable to create and disseminate accurate light curves rapidly. A…
GRB 060714: No Clear Dividing Line Between Prompt Emission and X-ray Flares
H. A. Krimm, J. Granot, F. Marshal +6
The long gamma-ray burst GRB 060714 was observed to exhibit a series of five X-ray flares beginning ~70 s after the burst trigger T0 and continuing until T0 + ~200 s. The first two…
X-ray Flares in Early GRB Afterglows
D. N. Burrows, A. Falcone, G. Chincarini +12
The Swift X-ray Telescope (XRT) has discovered that flares are quite common in early X-ray afterglows of Gamma-Ray Bursts (GRBs), being observed in roughly 50% of afterglows with p…
