Early Enrichment of Quasars by First Stars
Aparna Venkatesan, Raffaella Schneider, Andrea Ferrara
Studies of the broad emission-line regions (BLRs) in quasars have revealed solar or higher enrichment levels up to the highest redshifts. In combination with the presence of large…
Dust Formation in Very Massive Primordial Supernovae
R. Schneider, A. Ferrara, R. Salvaterra
At redshift z>5 Type II supernovae (SNII) are the only known dust sources with evolutionary timescales shorter than the Hubble time. We extend the model of dust formation in the ej…
The Detectability of the First Stars and Their Cluster Enrichment Signatures
Evan Scannapieco, Raffaella Schneider, Andrea Ferrara
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 f…
