Scientific paper

Data on all gamma-ray bursts observed through the end of 1974 are analyzed in order to estimate the relative distance of the origin of each burst on the assumption of a constant intrinsic source luminosity. A remarkable similarity is found between the galactic distributions of gamma-ray bursts and supernova remnants, suggesting a generic relation between the two as well as a galactic origin for the bursts. A model is proposed whereby the gamma-ray bursts originate from the disruption of 'cool' (i.e., completely run-down) neutron stars in the Galaxy. It is noted that this model can account for many observed features of the bursts and predicts an anisotropy in the burst arrival directions. An analysis of the latitude dependence of 16 gamma-ray bursts is cited which suggests that gamma-ray burst sources do cluster near the galactic equator.
