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=…
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…
Bridging Machine Learning and Cosmological Simulations: Using Neural Operators to emulate Chemical Evolution
Pelle van de Bor, John Brennan, John A. Regan +1
The computational expense of solving non-equilibrium chemistry equations in astrophysical simulations poses a significant challenge, particularly in high-resolution, large-scale co…
Predicting the number density of heavy seed massive black holes due to an intense Lyman-Werner field
Hannah O'Brennan, John A. Regan, John Brennan +5
The recent detections of a large number of candidate active galactic nuclei at high redshift (i.e. ) has increased speculation that heavy seed massive black hole forma…
