Description
The high masses and early formation epochs of the first stars make their black hole remnants the natural candidates for being the seeds of supermassive black holes (SMBHs). Alternatively, the so-called direct collapse scenario for SMBH seed formation has been proposed. I this talk, I will first present the physical processes governing the formation of supermassive stars and their collapse into intermediate-mass black holes. I will then discuss the efficiency of the subsequent BH mass growth by accretion
in early galaxies.
