Study of Very Short GRB: New Results from BATSE and KONUS

Astrophysics 2009-11-13 v1

Abstract

Our recent studies of Very Short Gamma Ray Bursts (VSB) of duration T_{90} \le 100 ms have indicated a significant angular asymmetry and a uniform V/V_{max} distribution from the BATSE data. Here we update these studies, and we extend our research to events observed with KONUS satellite which gives a new insight into the spectra not possible with the BATSE data. KONUS has observed 18 events with T_{90} \le 100 ms duration. These events display considerable numbers of photons with energies above 1 MeV and have photons above 5 MeV in all cases. These appear to be some of the most energetic photons observed from any classes of GRB to date.
