The Swift Gamma-Ray Burst Mission

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.
Optical and Long-Wavelength Afterglow from Gamma-Ray Bursts
- P. Mészáros, M. Rees
- Physics
- 6 June 1996
We discuss the evolution of cosmological gamma-ray burst remnants, consisting of the cooling and expanding fireball ejecta together with any swept-up external matter, after the gamma-ray event. We…

An extremely luminous X-ray outburst at the birth of a supernova

- 13 February 2008
This work reports the serendipitous discovery of a supernova at the time of the explosion, marked by an extremely luminous X-ray outburst, and attributes the outburst to the ‘break-out’ of the supernova shock wave from the progenitor star, and shows that the inferred rate of such events agrees with that of all core-collapse supernovae.
High-energy radiation from magnetized neutron stars

- 1 June 1992
The primary concern is with electromagnetic processes in the magnetospheres of neutron start, as opposed to the physics of their internal structure and evolution. The first six chapters provide a…
Unsteady outflow models for cosmological gamma-ray bursts
- M. Rees, P. Mészáros
- Physics
- 18 April 1994
The 'event' that triggers a gamma-ray burst cannot last for more than a few seconds. This is, however, long compared with the dynamical timescale of a compact stellar-mass object (approximately 10…
Relativistic fireballs: energy conversion and time-scales
- M. Rees, P. Mészáros
- Physics
- 1 September 1992
The expansion energy of a relativistic fireball can be reconverted into radiation when it interacts with an external medium. For expansion with Lorentz factors greater than or approximately equal to…
Theories of Gamma-Ray Bursts

- 8 November 2001
▪ Abstract The gamma ray burst phenomenon is reviewed from a theoretical point of view, with emphasis on the fireball shock scenario of the prompt emission and the longer wavelength afterglow. Rece...
Gamma-Ray Burst Early Optical Afterglows: Implications for the Initial Lorentz Factor and the Central Engine
- Bing Zhang, S. Kobayashi, P. Mészáros
- Physics
- 25 February 2003
Early optical afterglows have been observed from GRB 990123, GRB 021004, and GRB 021211, which reveal rich emission features attributed to reverse shocks. It is expected that Swift will discover many…
GRB Radiative Efficiencies Derived from the Swift Data: GRBs versus XRFs, Long versus Short
- Bing Zhang, En-Wei Liang, R. Willingale
- Physics
- 5 October 2006
The shallow decay component commonly existing in early X-ray afterglows, if interpreted as continuous energy injection in the external shock, suggests that the GRB efficiencies previously derived from the late-time X-rays were not reliable.
