Abstract

The BATSE instrument on the Compton Gamma-Ray Observatory has demonstrated that we live near the center of an isotropic but bounded distribution of gamma-ray burst sources but has left unsettled whether the bursts occur in our own Galaxy or at cosmological distances. Because a distance and energy scale is crucial to constraining burst models, this distance ambiguity must be resolved. The key experiment that would distinguish the possibilities is a search for bursts from the halo of M31 or other nearby galaxies. We discuss the observational prospects for this test, showing that no telescope now in orbit or scheduled for launch can settle the debate, but that an experiment could be done with a low-cost, dedicated instrument.
