The origin of supermassive black holes (with ≳109 M ⊙) in the early universe (redshift z ∼ 7) remains poorly understood. Gravitational collapse of a massive primordial gas cloud is a promising initial process, but theoretical studies have difficulty growing the black hole fast enough. We focus on the magnetic effects on star formation that occurs in an atomic-cooling gas cloud. Using a set of three-dimensional magnetohydrodynamic simulations, we investigate the star formation process in the… Expand


Direct collapse of supermassive stars (SMSs) is a possible pathway for generating supermassive black holes in the early universe. It is expected that an SMS could form via very rapid mass accretionExpand
The Formation of Population III Stars in Gas Accretion Stage: Effects of Magnetic Fields
The formation of Population III stars is investigated using resistive magnetohydrodynamic simulations. Starting from a magnetized primordial prestellar cloud, we calculate the cloud evolution severalExpand
Intermittent fragmentation and statistical variations during gas collapse in magnetized atomic cooling haloes
Observations reveal the presence of supermassive black holes (SMBH) as early as ~700 million years after the Big Bang. Their formation path is still subject to current debate. We explore theExpand
Angular momentum transfer in primordial discs and the rotation of the first stars
We investigate the rotation velocity of the first stars by modelling the angular momentum transfer in the primordial accretion disc.Assessing the impact of magnetic braking, we consider theExpand
Formation of massive black holes in rapidly growing pre-galactic gas clouds
A radiation hydrodynamics simulation of early galaxy formation suggests that the dynamics of structure formation, rather than the Lyman–Werner flux, drives the formation of massive black holes in the early Universe. Expand
Magnetohydrodynamics of Population III Star Formation
Jet-driving and fragmentation processes in a collapsing primordial cloud are studied using three-dimensional MHD nested grid simulations. Starting from a rotating magnetized spherical cloud with aExpand
Small-scale dynamo action during the formation of the first stars and galaxies - I. The ideal MHD limit
We explore the amplification of magnetic seeds during the formation of the first stars and galaxies. During gravitational collapse, turbulence is created from accretion shocks, which may act toExpand
The formation of massive black holes in z ∼ 30 dark matter haloes with large baryonic streaming velocities
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 ‘directExpand
Population III Star Formation in a ΛCDM Universe. I. The Effect of Formation Redshift and Environment on Protostellar Accretion Rate
We perform 12 extremely high resolution adaptive mesh refinement cosmological simulations of Population III star formation in a ΛCDM universe, varying the box size and large-scale structure, toExpand
Accretion-driven turbulence as universal process: galaxies, molecular clouds, and protostellar disks
Context. Even though turbulent motions are found everywhere in astrophysical systems, the origin of this turbulence is poorly understood. When cosmic structures form, they grow in mass via accretionExpand
