Spectra and light curves of gamma-ray burst afterglows
The recently discovered gamma-ray burst afterglow is believed to be described reasonably well by synchrotron emission from a decelerating relativistic shell that collides with an external medium. ToExpand
Gamma-ray bursts and the fireball model
Abstract Gamma-ray bursts (GRBs) have puzzled astronomers since their accidental discovery in the late 1960s. The BATSE detector on the COMPTON-GRO satellite has been detecting one burst per day forExpand
Predictions for the Very Early Afterglow and the Optical Flash
According to the internal-external shocks model for gamma-ray bursts (GRBs), the GRB is produced by internal shocks within a relativistic flow while the afterglow is produced by external shocks withExpand
The physics of gamma-ray bursts
Gamma-ray bursts (GRB's), short and intense pulses of low-energy $\ensuremath{\gamma}$ rays, have fascinated astronomers and astrophysicists since their unexpected discovery in the late sixties.Expand
Jets in Gamma-Ray Bursts
In the afterglows of several gamma-ray bursts (GRBs), rapid temporal decay, which is inconsistent with spherical (isotropic) blast-wave models, is observed. In particular, GRB 980519 had the mostExpand
Relativistic ejecta from X-ray flash XRF 060218 and the rate of cosmic explosions
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
The luminosity function and the rate of Swift's Gamma Ray Bursts
We invert directly the redshift-luminosity distribution of observed long Swift gamma-ray bursts (GRBs) to obtain their rate and luminosity function. Our best-fitting rate is described by a brokenExpand
Nucleosynthesis, neutrino bursts and γ-rays from coalescing neutron stars
NEUTRON-STAR collisions occur inevitably when binary neutron stars spiral into each other as a result of damping of gravitational radiation. Such collisions will produce a characteristic burst ofExpand
The afterglow, redshift and extreme energetics of the γ-ray burst of 23 January 1999
Long-lived emission, known as afterglow, has now been detected from about a dozen γ-ray bursts. Distance determinations place the bursts at cosmological distances, with redshifts, z, ranging from ∼1Expand
The afterglow of GRB 050709 and the nature of the short-hard γ-ray bursts
The final chapter in the long-standing mystery of the γ-ray bursts (GRBs) centres on the origin of the short-hard class of bursts, which are suspected on theoretical grounds to result from theExpand
