Hierarchical Black Hole Mergers at High Redshift: Predictions for LISA and LGWA from SEEDZ
Daxal H. Mehta, Lewis R. Prole, John A. Regan +13
We investigate the hierarchical assembly of black holes (BHs) in the early Universe using the next-generation SEEDZ cosmological zoom-in simulations. Our suite follows two independ…
SEEDZ: Rapid Galaxy Assembly as a Pathway to Supermassive Stars, Dense Stellar Environments and Massive Black Hole Seeds
Lewis R. Prole, John A. Regan, Daxal Mehta +14
We investigate the assembly history of early galaxies in the SEEDZ hydrodynamic simulations, to investigate the high inflow rates believed to be required for the formation of super…
Black Hole Feedback, Galaxy Quenching and Outflows at Cosmic Dawn: Analysis of the SEEDZ Simulations
Lewis R. Prole, John A. Regan, Daxal Mehta +13
Here we analyse the growth and feedback effects of massive black holes (MBHs) in the SEEDZ simulations. The most massive black holes grow to masses of M by $z=…
Growth of Light Seed Black Holes in the Early Universe
Daxal H. Mehta, John A. Regan, Lewis Prole
Observations from the James Webb Space Telescope (JWST) have uncovered supermassive black holes (SMBHs) with masses exceeding at redshifts , posing…
The SEEDZ Simulations: Methodology and First Results on Massive Black Hole Seeding and Early Galaxy Growth
Lewis R. Prole, John A. Regan, Daxal Mehta +13
Here we introduce the SEEDZ simulations, a suite of cosmological hydrodynamic simulations exploring the formation and growth of the first massive black holes in the Universe. SEEDZ…
Primordial black holes in cosmological simulations: growth prospects for supermassive black holes
Lewis R. Prole, John A. Regan, Daxal Mehta +2
It has long been suggested that a fraction of the dark matter in the Universe could exist in the form of primordial black holes (PBHs) that have existed since the radiation dominat…
NEATH IV: an early onset of complex organic chemistry in molecular clouds
F. D. Priestley, P. C. Clark, S. E. Ragan +6
Complex organic molecules (COMs) are widely detected in protostellar and protoplanetary systems, where they are thought to have been inherited in large part from earlier evolutiona…
Halo Mergers Enhance the Growth of Massive Black Hole Seeds
Lewis R. Prole, John A. Regan, Daniel J. Whalen +2
High redshift observations of 10 M supermassive black holes (SMBHs) at and `Little Red Dots' that may host overmassive black holes at suggests the exist…
Growth of Light-Seed Black Holes in Gas-Rich Galaxies at High Redshift
Daxal Mehta, John A. Regan, Lewis Prole
Recent observations by the James Webb Space Telescope confirm the existence of massive black holes ( ) beyond the redshift of . However, their formatio…
Gravitational collapse at low to moderate Mach numbers: The relationship between star formation efficiency and the fraction of mass in the massive object
Jorge Saavedra-Bastidas, Dominik R. G. Schleicher, Ralf S. Klessen +7
The formation of massive objects via gravitational collapse is relevant both for explaining the origin of the first supermassive black holes and in the context of massive star form…
NEATH III: a molecular line survey of a simulated star-forming cloud
F. D. Priestley, P. C. Clark, S. C. O. Glover +4
We present synthetic line observations of a simulated molecular cloud, utilising a self-consistent treatment of the dynamics and time-dependent chemical evolution. We investigate l…
Heavy Black Hole Seed Formation in High-z Atomic Cooling Halos
Lewis R. Prole, John A. Regan, Simon C. O. Glover +3
Halos with masses in excess of the atomic limit are believed to be ideal environments in which to form heavy black hole seeds with masses above 10^3 Msun. In cases where the H_2 fr…
NEATH II: NH as a tracer of imminent star formation in quiescent high-density gas
F. D. Priestley, P. C. Clark, S. C. O. Glover +4
Star formation activity in molecular clouds is often found to be correlated with the amount of material above a column density threshold of . Attempt…
Population III star formation: multiple gas phases prevent the use of an equation of state at high densities
Lewis R. Prole, Paul C. Clark, Felix D. Priestley +2
Advanced primordial chemistry networks have been developed to model the collapse of metal-free baryonic gas within the gravitational well of dark matter (DM) halos and its subseque…
Non-Equilibrium Abundances Treated Holistically (NEATH): the molecular composition of star-forming clouds
F. D. Priestley, P. C. Clark, S. C. O. Glover +4
Much of what we know about molecular clouds, and by extension star formation, comes from molecular line observations. Interpreting these correctly requires knowledge of the underly…
From dark matter halos to pre-stellar cores: High resolution follow-up of cosmological Lyman-Werner simulations
Lewis R. Prole, Anna T. P. Schauer, Paul C. Clark +3
Molecular hydrogen allows cooling in primordial gas, facilitating its collapse into Population III stars within primordial halos. Lyman-Werner (LW) radiation from these stars can e…
Primordial magnetic fields in Population III star formation: a magnetised resolution study
Lewis Prole, Paul Clark, Ralf Klessen +2
Population III stars form in groups due to the fragmentation of primordial gas. While uniform magnetic fields have been shown to support against fragmentation in present day star f…
Fragmentation induced starvation in Population III star formation: a resolution study
Lewis R. Prole, Paul C. Clark, Ralf S. Klessen +1
The Population III initial mass function (IMF) is currently unknown, but recent studies agree that fragmentation of primordial gas gives a broader IMF than the initially suggested…
