Further Evidence for Some Gamma‐Ray Bursts Consistent with Primordial Black Hole Evaporation

Abstract

Previously we identified some short burst events from the BATSE 1B catalog that were consistent with an origin of primordial black hole evaporation at the quark-gluon phase transition. We showed that these events are also consistent with arising from a homogeneous spatial distribution. Recently the PHEBUS group has also indicated that the short bursts are consistent with V/Vmax ~ 1/2. In this paper we describe the results of the study of the BATSE 3B catalog shape that confirm the results from BATSE 1B.
