How to raise a supermassive black hole: interpreting early JWST AGN with the AESOPICA simulations
Sophie Koudmani, Jan Scholtz, Anthony J. Taylor +11
The active black holes uncovered by JWST in the early Universe are highly abundant and seemingly overmassive with respect to local scaling relations, challenging standard models of…
Comparing gravitational wave background predictions from cosmological simulations to pulsar timing observations
Stephanie Buttigieg, Debora Sijacki, Christopher J. Moore +2
The recent detection of a gravitational wave background (GWB) by pulsar timing arrays (PTAs) may represent the first evidence of gravitational waves from merging supermassive black…
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…
Dust destruction signals shock-accelerated outflows in the nearby active galaxy NGC 1068
Luke R. Holden, Clive N. Tadhunter, Daniel J. B. Smith +3
Massive gas outflows driven by active galactic nuclei (AGN) are a key ingredient in models of galaxy evolution, in which they are required to regulate star formation and thus expla…
Small hosts, big appetites: unveiling rapid and early low-mass black hole growth in cosmological zoom-in simulations of dwarf galaxies
Giulia Ortame, Martin A. Bourne, Sophie Koudmani +3
Dwarf galaxies are ideal laboratories to probe the interplay between galaxy formation and the growth of black holes (BHs) in the early Universe. Mounting observational evidence rev…
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=…
