Observations of quasars at redshifts z > 6 reveal that 10^9 Msol supermassive black holes (SMBHs) had already formed when the Universe was 20. This is the regime where baryonic streaming motions--the relative velocities of baryons with respect to dark matter in the early Universe--most strongly inhibit star formation by suppressing gas infall and cooling. We investigate the impact of this effect on the growth of the first SMBHs using a suite of high-fidelity, ellipsoidal-collapse Monte Carlo…

Impact of baryonic streaming velocities on the formation of supermassive black holes via direct collapse
Baryonic streaming motions produced prior to the epoch of recombination became supersonic during the cosmic dark ages. Various studies suggest that such streaming velocities change the halo

The origins of the � 10 9 M J quasar supermassive black holes (BHs) at redshifts z > 6 remain a theoretical puzzle. One possibility is that they grew from � 10 5 M J BHs formed in the ‘direct
Driving the growth of the earliest supermassive black holes with major mergers of host galaxies
The formation mechanism of supermassive black holes (SMBHs) in general, and of ∼ 10 9 M ⊙ ?> SMBHs observed as luminous quasars at redshifts z > 6 ?> in particular, remains an open fundamental
High-redshift supermassive black holes: accretion through cold flows
We use zoom-in techniques to re-simulate three high-redshift (z > 5.5) halos which host 10^9 solar mass blackholes from the ~ Gpc volume, MassiveBlack cosmological hydrodynamic simulation. We examine

The impact of ionizing radiation on the formation of a supermassive star in the early Universe
A massive primordial halo near an intensely star-forming galaxy may collapse into a supermassive star (SMS) and leave a massive black hole seed of about 10^5 M_⊙. To investigate the impact of
The suppression of direct collapse black hole formation by soft X-ray irradiation
The origin of supermassive black holes (SMBHs) in galactic nuclei is one of the major unsolved problems in astrophysics. One hypothesis is that they grew from >10^5 M_sun black holes that formed in
Supersonic Relative Velocity between Dark Matter and Baryons: A Review
In this review we summarize the effect of relative supersonic velocities between gas and dark matter created right after recombination on astrophysics and cosmology. The relative velocities formally
Formation of Supermassive Black Hole Seeds
Abstract The detection of quasars at z > 6 unveils the presence of supermassive black holes of a few billion solar masses. The rapid formation process of these extreme objects remains a fascinating

Using adiabatic high-resolution numerical simulations we quantify the effect of the streaming motion of baryons with respect to dark matter at the time of recombination on structure formation and

THE ASSEMBLY OF SUPERMASSIVE BLACK HOLES AT HIGH REDSHIFTS
The supermassive black holes (SMBHs) massive enough (≳ few ×109 M☉) to power the bright redshift z ≈ 6 quasars observed in the Sloan Digital Sky Survey (SDSS) are thought to have assembled by mergers

If supermassive black holes (SMBHs) are the energy sources that power quasars and active galactic nuclei (AGNs), then QSO SDSS 1148+5251, the quasar with the highest redshift (zQSO = 6.43), hosts an
