The leading contenders for the seeds of z > 6 quasars are direct-collapse black holes (DCBHs) forming in atomically cooled haloes at z ∼ 20. However, the Lyman–Werner (LW) UV background required to form DCBHs of 105 M⊙ are extreme, about 104 J21, and may have been rare in the early universe. Here we investigate the formation of intermediate-mass black holes (IMBHs) under moderate LW backgrounds of 100 and 500 J21, which were much more common at early times. These backgrounds allow haloes to…

The Birth Mass Function of Population III Stars
Population III stars ended the cosmic dark ages and began early cosmological reionization and chemical enrichment. However, in spite of their importance to the evolution of the early universe, their
Radio Power from Direct-collapse Black Holes
Direct-collapse black holes (DCBHs) forming at z ∼ 20 are currently the leading candidates for the seeds of the first quasars, over 200 of which have now been found at z > 6. Recent studies suggest

The Birth of Binary Direct-collapse Black Holes
Supermassive primordial stars forming during catastrophic baryon collapse in atomically-cooling halos at $z \sim$ 15 - 20 may be the origin of the first quasars in the universe. However, no
Star formation in the first galaxies – I. Collapse delayed by Lyman–Werner radiation
We investigate the process of metal-free star formation in the first galaxies with a high-resolution cosmological simulation. We consider the cosmologically motivated scenario in which a strong
On the number density of 'direct collapse' black hole seeds
Supermassive black holes (BHs) reside in the centre of most local galaxies, but they also power active galactic nuclei and quasars, detected up to z = 7. These quasars put constraints on early BH
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
The impact of reionization on the formation of supermassive black hole seeds
Direct collapse black holes (DCBHs) formed from the collapse of atomically-cooled primordial gas in the early Universe are strong candidates for the seeds of supermassive BHs. DCBHs are thought to
Ubiquitous seeding of supermassive black holes by direct collapse
We study for the first time the environment of massive black hole (BH) seeds (∼10 4−5 M� ) formed via the direct collapse of pristine gas clouds in massive haloes (≥10 7 M� )a tz > 6. Our model is
The seeds of supermassive black holes and the role of local radiation and metal spreading
Abstract We present cosmological hydrodynamical simulations including atomic and molecular non-equilibrium chemistry, multi-frequency radiative transfer (0.7–100 eV sampled over 150 frequency bins)
FORMATION OF THE FIRST NUCLEAR CLUSTERS AND MASSIVE BLACK HOLES AT HIGH REDSHIFT
We present a model for the formation of massive black holes (~1000 M ☉) due to stellar-dynamical processes in the first stellar clusters formed at early cosmic times (z ~ 10-20). These black holes
THE FORMATION OF SUPERMASSIVE BLACK HOLES FROM LOW-MASS POP III SEEDS
The existence of 109 M ☉ black holes (BHs) in massive galaxies by z ~ 7 is one of the great unsolved mysteries in cosmological structure formation. One theory argues that they originate from the BHs
Supermassive black hole formation by cold accretion shocks in the first galaxies
We propose a new scenario for supermassive star (SMS: >rsim 105 M⊙) formation in shocked regions of colliding cold accretion flows near the centres of the first galaxies. Recent numerical simulations
