Abstract

Metal enrichment of clusters of galaxies by proto-galactic star formation is discussed. We show that the observational requirement of metal ejection from proto-galaxies into the intracluster medium(ICM) suggests pregalactic massive star formation bursts in the extended halo of proto-galaxies. Our results predict that galaxies have an extended halo populated with a number of supernova remnants. The predicted large radius of the extended halo of our Galaxy is consistent with the distribution of -γ- ray bursters observed by BATSE on the Gamma Ray Observatory (GRO) satellite, if neutron stars possibly formed in the extended halo of the Galaxy are the source of γ- ray bursters.
