Abstract: Supermassive stars (SMSs) with $\sim10^{4-5}~\mathrm{M}_{\odot}$ are candidate objects for the origin of supermassive black holes observed at redshift $z$>6. They are supposed to form in primordial-gas clouds that provide the central stars with gas at… read more here.

Abstract: The assembly of supermassive black holes poses a challenge primarily because of observed quasars at high redshift, but additionally because of the current lack of observations of intermediate mass black holes. One plausible scenario for… read more here.

Concurrent formation of supermassive stars and globular clusters: implications for early self-enrichment

DOI: 10.1093/mnras/sty1059
Abstract: We present a model for the concurrent formation of globular clusters (GCs) and supermassive stars (SMSs, ≳103 M⊙) to address the origin of the HeCNONaMgAl abundance anomalies in GCs. GCs form in converging gas flows and… read more here.
