Black holes of a billion solar masses are observed in the infant universe a few hundred million years after the Big Bang. The direct collapse of protogalactic gas clouds in primordial halos with $\rm T_{vir} \geq 10^{4} K$ provides the most promising way to assemble massive black holes. In this study, we aim to determine the characteristic mass scale of seed black holes and the time evolution of the accretion rates resulting from the direct collapse model. We explore the formation of…

Cosmological direct-collapse black hole formation sites hostile for their growth
The direct collapse (DC) is a promising mechanism that provides massive seed black holes (BHs) with ∼105 M⊙ in the early universe. To study a long-term accretion growth of a direct-collapse black
Formation of massive seed black holes via collisions and accretion
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
Simulating the formation of massive seed black holes in the early Universe. I: An improved chemical model
The direct collapse model for the formation of massive seed black holes in the early Universe attempts to explain the observed number density of supermassive black holes (SMBHs) at $z \sim 6$ by
Possible Evolution of Supermassive Black Holes from FRI quasars
We explore the question of the rapid buildup of black hole mass in the early universe employing a growing black hole mass-based determination of both jet and disk powers predicted in recent
Formation of Supermassive Black Hole Seeds in the First Galaxies
Frontier observations of quasars at redshifts z ≳ 6 suggest the existence of supermassive black holes of masses ≃ 109 M⊙ when the Universe was less than a billion years old. These objects most likely

The existence of black holes in the intermediate mass interval between one hundred and ten thousand solar masses, filling the gap between the stellar and the supermassive black holes is a key
Forming massive seed black holes in high-redshift quasar host progenitors
The presence of massive black holes (BHs) with masses of the order of $10^9\, {\rm M_\odot }$, powering bright quasars when the Universe was less than 1 Gyr old, poses strong constraints on their
Assessing inflow rates in atomic cooling haloes: implications for direct collapse black holes
Supermassive black holes are not only common in the present-day galaxies, but billion solar masses black holes also powered z≥ 6 quasars. One efficient way to form such black holes is the collapse of
Magnetic fields during the formation of supermassive black holes
Observations of quasars at z > 6 report the existence of a billion solar mass black holes. Comprehending their formation in such a short time scale is a matter of ongoing research. One of the most
COSMOLOGICAL SIMULATIONS OF EARLY BLACK HOLE FORMATION: HALO MERGERS, TIDAL DISRUPTION, AND THE CONDITIONS FOR DIRECT COLLAPSE
Gravitational collapse of a massive primordial gas cloud is thought to be a promising path for the formation of supermassive black holes in the early universe. We study conditions for the so-called

Black hole formation in the early Universe
Supermassive black holes with up to a $\rm 10^{9}~M_{\odot}$ dwell in the centers of present-day galaxies, and their presence has been confirmed at z $\geq$ 6. Their formation at such early epochs is
ACCRETION ONTO THE FIRST STELLAR-MASS BLACK HOLES
The first stars, forming at redshifts z > 15 in minihalos with M ∼ 105–6 M☉ may leave behind remnant black holes, which could conceivably have been the “seeds” for the supermassive black holes

In this paper, we discuss the evolution of gravitationally unstable pre-galactic discs that result from the collapse of haloes at high redshift z ≈ 10 or so, which have not yet been enriched by
Formation of supermassive black holes by direct collapse in pre-galactic haloes
We describe a mechanism by which supermassive black holes (SMBHs) can form directly in the nuclei of protogalaxies, without the need for 'seed' black holes left over from early star formation.

TLDR
