Observation of two gamma-ray bursts by Vela X-ray detectors

  • 1. University of California, Los Alamos National Laboratory

Description

Bursts of X-rays coincident in time with two gamma-ray burst events were observed by the 3--12 keV collimated X-ray detectors on the Vela spacecraft. Both of these observations show recurrence on a time scale of hundreds of seconds. For one of these events (GB 7200514) the X-ray detection gives an improved position as well as information on the spectrum late in the outburst. The other event (GB 740723) is of special interest because the source, not previously located, is consistent in direction with the binary pulsar SMC X-1 in the Small Magellanic Cloud; this is the first moderately small error box for a gamma-ray burst to contain a strong X-ray source
