Formation of massive seed black holes via collisions and accretion
Boekholt, Tjarda; Schleicher, D.; Fellhauer, M.; Klessen, R.; Reinoso, B.; Stutz, A.; Haemmerle, L.Models aiming to explain the formation of massive black hole seeds, and in particular the direct collapse scenario, face substantial difficulties. These are rooted in rather ad hoc and fine-tuned initial conditions, such as the simultaneous requirements of extremely low metallicities and strong radiation backgrounds. Here, we explore a modification of such scenarios where a massive primordial star cluster is in...
