Abstract

Gamma Ray Bursts (GRBs) are short bursts of gamma rays lasting from a small fraction of a second to a few hundred seconds that are observed from random directions of the sky at a frequency of roughly once per day. A small sample of gamma ray burst light curves is shown in Fig. 19.1. Bursts are identified as “GRB yymmdd”, where yy stands for the year, mm the month, and dd the day of the event. When more than one burst occurs at any given date a letter is added to distinguish between them. Bursts show a wide variety of light curve shapes and structure. Clearly this variety does not provide much in terms of clue as to the physical origin of the GRBs, excepting the fact that the sources are small, a small fraction of a light second, with some proviso for relativistic effects.
