High-redshift AGN population in radiation-hydrodynamics simulations
Teodora-Elena Bulichi, Oliver Zier, Aaron Smith +7
High-redshift active galactic nuclei (AGN) have long been recognized as key probes of early black hole growth and galaxy evolution. However, modeling this population remains diffic…
Introducing the THESAN-ZOOM project: radiation-hydrodynamic simulations of high-redshift galaxies with a multi-phase interstellar medium
Rahul Kannan, Ewald Puchwein, Aaron Smith +11
We introduce the THESAN-ZOOM project, a comprehensive suite of high-resolution zoom-in simulations of high-redshift () galaxies selected from the THESAN simulation volume…
Constraints on Primordial Magnetic Fields from the Lyman-α forest
Mak PaviÄeviÄ, Vid IrÅ¡iÄ, Matteo Viel +5
We present the first constraints on primordial magnetic fields from the Lyman- forest using full cosmological hydrodynamic simulations. At the scales and redshifts probed by th…
The impact of faint AGN discovered by JWST on reionization
Shikhar Asthana, Martin G. Haehnelt, Girish Kulkarni +4
The relative contribution of emission from stellar sources and accretion onto supermassive black holes to reionization has been brought into focus again by the apparent high abunda…
How Early Could the Milky Way's Disk Form?
Vadim A. Semenov, Charlie Conroy, Aaron Smith +2
We investigate early, , galaxy formation in a cosmological zoom-in simulation of a close, early-forming Milky Way (MW) analog extracted from TNG50 simulation and resimulated…
The THESAN-ZOOM project: Long-term imprints of external reionization on galaxy evolution
Oliver Zier, Rahul Kannan, Aaron Smith +8
We investigate the impact of ionizing external ultraviolet (UV) radiation on low-mass haloes () at high redshift using baryonic resolution zoom-…
