We provide a comprehensive review of major developments in our understanding of gamma-
ray bursts, with particular focus on the discoveries made within the last fifteen years when …

Due to relativistic bulk motion, the structure and orientation of gamma-ray burst (GRB) jets
have a fundamental role in determining how they appear. The recent discovery of the …

ABSTRACT The Swift/Burst Alert Telescope (BAT) hard X-ray transient monitor provides
near real-time coverage of the X-ray sky in the energy range 15–50 keV. The BAT observes …

ABSTRACT To date, the Burst Alert Telescope (BAT) onboard Swift has detected∼ 1000
gamma-ray bursts (GRBs), of which∼ 360 GRBs have redshift measurements, ranging from …

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 …

We estimate the rate and the luminosity function of short (hard) Gamma-Ray Bursts (sGRBs)
that are non-Collapsars, using the peak fluxes and redshifts of BATSE, Swift and Fermi …

One favored progenitor model for short duration gamma-ray bursts (GRBs) is the
coalescence of two neutron stars (NS–NS). One possible outcome of such a merger would …

We present a catalog of radio afterglow observations of gamma-ray bursts (GRBs) over a 14
year period from 1997 to 2011. Our sample of 304 afterglows consists of 2995 flux density …

Context. Gamma-ray bursts (GRBs) are the most energetics explosions in the Universe.
They are detectable up to very high redshifts. They may therefore be used to study the …

We present a systematic temporal and spectral study of all Swift-X-ray Telescope
observations of gamma-ray burst (GRB) afterglows discovered between 2005 January and …
