In this article, the relative role of three seed populations in the formation of supermassive black holes (SMBHs) within an Eddington-limited gas accretion scenario was investigated.Abstract:
Observations of hyper-luminous quasars at $z>6$ reveal the rapid growth of supermassive black holes (SMBHs $>10^9 \rm M_{\odot}$) whose origin is still difficult to explain. Their progenitors may have formed as remnants of massive, metal free stars (light seeds), via stellar collisions (medium-weight seeds) and/or massive gas clouds direct collapse (heavy seeds). In this work we investigate for the first time the relative role of these three seed populations in the formation of $z>6$ SMBHs within an Eddington-limited gas accretion scenario. To this aim, we implement in our semi-analytical data-constrained model a statistical description of the spatial fluctuations of Lyman-Werner (LW) photo-dissociating radiation and of metal/dust enrichment. This allows us to set the physical conditions for BH seeds formation, exploring their relative birth rate in a highly biased region of the Universe at $z>6$. We find that the inclusion of medium-weight seeds does not qualitatively change the growth history of the first SMBHs: although less massive seeds ($ 15$.read more

TL;DR: In this paper , the authors investigated the early evolution of the first supermassive black holes (SMBHs) by constraining their distribution in mass and luminosity at z > 4, focusing on the poorly explored low-mass end of the nuclear black hole (BH) distribution down to z ' 4.

TL;DR: The a-sloth model as mentioned in this paper is based on dark matter merger trees that can either be generated based on Extended Press-Schechter theory or be imported from dark matter simulations, and applies analytical recipes for baryonic physics to model the formation of both metal-free and metal-poor stars and the transition between them.
