The Metallicity of Pregalactic Globular Clusters: The Observational Consequences of the First Stars
We explore a scenario in which metal-poor globular clusters (GCs) are enriched by the first supernovae in the universe. If the first stars in a 107 Msolar dark halo were very massive (>180 Msolar), then a pair-instability supernova from a single massive star could produce sufficient iron to enrich 106 Msolar of pristine, primordial gas to [Fe/H]~-2
