The Detectability of the First Stars and Their Cluster Enrichment Signatures

open access: yesThe Astrophysical Journal, 2003
We conduct a comprehensive investigation of the detectability of the first stars and their enrichment signatures in galaxy clusters. We show that the mean metallicity of outflows from objects containing these Population III (PopIII) stars is well above the critical transition metallicity (Z_cr \sim 10^-4) that marks the formation of normal stars.
