Are Gamma-Ray Bursts Indeed Correlated with Abell Clusters of Galaxies?

摘要

We study the possible correlation of a selected sample of 87 gamma-ray bursts that can be localized to ≤6616 Abell clusters of galaxies (with |b| > 30 deg) for which we have de- termined angular sizes. The deg~2 with 3intention is to confirm whether the bursts are related to Abell clusters of galaxies, as has been claimed by researchers who found a 95/100 confidence level correlation between Abell clusters and a subsample of 136 events from the BATSE 3B catalog.
