TL;DR: In this paper, the duration distribution of the gamma-ray bursts of the first BATSE catalog is studied and a bimodality in the distribution is found, which separates GRBs into two classes: short events (less than 2 s) and longer ones (more than 2 S).

TL;DR: In this paper, the authors reported the discovery of transient optical emission in the error box of the gamma-ray burst GRB980425, the light curve of which was very different from that of previous optical afterglows associated with Gamma-ray bursts.

TL;DR: In this article, the authors reported the discovery of an optical transient, in the BeppoSAX Wide Field Camera error box of GRB980425, which occurred within about a day of the gamma-ray burst.
Journal ArticleDOI
Discovery of Intense Gamma-Ray Flashes of Atmospheric Origin

TL;DR: Detectors aboard the Compton Gamma Ray Observatory have observed an unexplained terrestrial phenomenon: brief, intense flashes of gamma rays that must originate in the atmosphere at altitudes above at least 30 kilometers in order to escape atmospheric absorption and reach the orbiting detectors.
Journal ArticleDOI

TL;DR: The current version (4Br) has been revised from the version first circulated on CD-ROM in September 1997 (4B) to include improved locations for a subset of bursts that have been reprocssed using additional data as discussed by the authors.
