Super-Eddington accretion in protogalactic cores
Tommaso Zana, Pedro R. Capelo, Mairo Boresta +6
The presence of massive black holes (BHs) exceeding already at redshift challenges standard models of BH growth. Super-Eddington (SE) accretion has…
Effective supernova dust yields from rotating and non-rotating stellar progenitors
Koki Otaki, Raffaella Schneider, Luca Graziani +4
Supernovae (SNe) are believed to be the dominant sources of dust production at high redshift. However, the reverse shock generated by the interaction of the SN forward shock and th…
