The Swift gamma-ray burst mission
TLDR
The Swift mission will determine the origin of GRB, classify GRBs and search for new types, study the interaction of the ultrarelativistic outflows of GRBs with their surrounding medium, and use GRBs to study the early universe out to z >10. Expand
The Swift X-Ray Telescope
TLDR
The X-ray telescope (XRT) enables Swift to determine GRB positions with a few arcseconds accuracy within 100 s of the burst onset, and will measure spectra and lightcurves of the GRB afterglow beginning about a minute after the burst and will follow each burst for days or weeks. Expand
Methods and results of an automatic analysis of a complete sample of Swift-XRT observations of GRBs
We present a homogeneous X-ray analysis of all 318 gamma-ray bursts detected by the X-ray telescope (XRT) on the Swift satellite up to 2008 July 23; this represents the largest sample of X-ray GRBExpand
An online repository of Swift/XRT light curves of Γ-ray bursts
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. Aims. To provide theExpand
The association of GRB 060218 with a supernova and the evolution of the shock wave
TLDR
A supernova is caught in the act of exploding, directly observing the shock break-out, which indicates that the GRB progenitor was a Wolf–Rayet star. Expand
Relativistic jet activity from the tidal disruption of a star by a massive black hole
TLDR
Observations of a bright X-ray flare from the extragalactic transient Swift J164449.3+573451 conclude that they have captured the onset of relativistic jet activity from a supermassive black hole. Expand
Determination of Confidence Limits for Experiments with Low Numbers of Counts
Two different methods, classical and Bayesian, for determining confidence intervals involving Poisson-distributed data are compared. Particular consideration is given to cases where the number ofExpand
Physical Processes Shaping Gamma-Ray Burst X-Ray Afterglow Light Curves: Theoretical Implications from the Swift X-Ray Telescope Observations
With the successful launch of the Swift Gamma-Ray Burst Explorer, a rich trove of early X-ray afterglow data has been collected by its onboard X-Ray Telescope (XRT). Some interesting features areExpand
Relativistic ejecta from X-ray flash XRF 060218 and the rate of cosmic explosions
TLDR
Radio and X-ray observations of XRF 060218 (associated with supernova SN 2006aj), the second-nearest GRB identified until now, are reported, showing that this event is a hundred times less energetic but ten times more common than cosmological GRBs. Expand
