Are Gamma-Ray Bursts the Sources of the Ultra-High Energy Cosmic Rays?

摘要

A checklist of criteria is presented to help establish the sources of ultra-high energy cosmic rays (UHECRs). These criteria are applied to long-duration GRBs in order to determine if they are UHECR sources. The evidence seems to favor blazars and radio galaxies (or other sources) over GRBs.
