Formation of massive black hole seeds in the early Universe: Runaway stellar collisions in the first star clusters
Abstract
The presence of supermassive black hole seeds when the Universe was only one billion years old, presents a big challenge to the actual models for the formation and growth of black holes, due to the short time imposed to gather 10 M in a single compact object. In this work, we present a mechanism for the formation of intermediate mass black holes (10 M), which consists in repeated mergers between population III.1 stars in the first dense star clusters formed in the Universe.
