Gamma-Ray Bursts

1991
We summarize the observed features of γ-ray bursts, with particular emphasis on the cyclotron lines seen in their spectra. We then discuss the theory of cyclotron resonant scattering, and compare the theoretical and observed line spectra. Finally, we mention some implications.

On the origin of gamma-ray bursts

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008
Gamma-ray bursts are the most energetic explosions in the Universe, occurring at cosmological distances. The initial phase of the emission from these bursts is predominantly of gamma rays and stems from a highly relativistic outflow. The nature of this emission is still under debate.

The theory of gamma-ray bursts

AIP Conference Proceedings, 1984
A γ-ray burst occurs when a strongly magnetic neutron star experiences either a thermonuclear explosion in degenerate material accumulated over a long period of time or the sudden, greatly super-Eddington accretion of matter. Certain aspects of the thermonuclear model are briefly reviewed and special attention is devoted to mechanisms for producing the

Swift observations of gamma-ray bursts

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007
Since its launch on 20 November 2004, the Swift mission has been detecting approximately 100 gamma-ray bursts (GRBs) each year, and immediately (within approx. 90 s) starting simultaneous X-ray and UV/optical observations of the afterglow.
