Session 43 - Source Surveys.
Display session, Wednesday, June 11
South Main Hall,
The statistical similarities in the time profiles of different BATSE Gamma-Ray Bursts (GRBs) are computed. We perform an automated statistical comparison for 1235 post-3B GRBs. Our latest results show that no two GRBs are alike to within the statistical limits of the data. GRBs that appear statistically similar in one energy channel are either dissimilar in other energy channels - even to within an arbitrary scale factor - or too dim for a significant statistical comparison.
One consequence of the above research is that no gravitational lenses have yet been found. Were GRBs intrinsically similar it would be harder to isolate lens event, so that the above results serve as a background against which the similarity of lensed GRBs must be compared.
