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…
X-ray flare in XRF 050406: evidence for prolonged engine activity
P. Romano, A. Moretti, P. L. Banat +33
We present observations of XRF 050406, the first burst detected by Swift showing a flare in its X-ray light curve. During this flare, which peaks at t_peak ~210s after the BAT trig…
The Giant X-ray Flare of GRB 050502B: Evidence for Late-Time Internal Engine Activity
A. D. Falcone, D. N. Burrows, D. Lazzati +28
Until recently, X-ray flares during the afterglow of gamma ray bursts (GRBs) were a rarely detected phenomenon, thus their nature is unclear. During the afterglow of GRB 050502B, t…
Swift and XMM observations of the dark GRB 050326
A. Moretti, A. De Luca, D. Malesani +30
We present Swift and XMM observations of GRB 050326, detected by Swift-BAT. The fluence was 7.7x10^-6 erg cm^-2 (20-150 keV), and its spectrum was hard, with a power law photon ind…
Swift observations of the prompt X-ray emission and afterglow from GRB050126 and GRB050219A
M. R. Goad
We report on the temporal and spectral characteristics of the early X-ray emission from the Gamma Ray Bursts GRB050126 and GRB050219A as observed by Swift. The X-ray light-curves o…
Swift observations of the X-ray bright GRB 050315
S. Vaughan, M. R. Goad, A. P. Beardmore +30
This paper discusses Swift observations of the gamma-ray burst GRB 050315 (z=1.949) from 80 s to 10 days after the onset of the burst. The X-ray light curve displayed a steep early…
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…
Swift observations of GRB050128: the early X-ray afterglow
S. Campana, L. A. Antonelli, G. Chincarini +33
Swift discovered GRB050128 with the Burst Alert Telescope and promptly pointed its narrow field instruments to monitor the afterglow. X-ray observations started 108 s after the tri…
The Discovery of the Optical and Near-IR Afterglows of the First Swift Gamma-Ray Bursts
E. Berger, D. B. Fox, S. R. Kulkarni +16
We present optical and near-infrared searches for afterglow emission from the first four Swift bursts with accurate positions from the X-ray Telescope (XRT). Using telescopes at La…
