New Evidence for The Cosmological Origin of Gamma-Ray Bursts
Tsafrir Kolatt, Tsvi Piran
Abstract
We find that Gamma-ray bursts (GRBs) at the 3B catalog are correlated (at 95\% confidence level) with Abell clusters. This is the first known correlation of GRBs with any other astronomical population. It confirms the cosmological origin of GRBs. Comparison of the rich clusters auto-correlation with the cross-correlation found here suggests that 26 15\% of an accurate (δ<2.3 deg.) position GRBs sub-sample members are located within 600 .
