The THESAN-ZOOM project: The Hidden Neighbours of OI Absorbers during Reionization
Giulia Pruto, Laura Keating, Rahul Kannan +9
Metal absorbers represent a powerful probe of galaxy feedback and reionization, as highlighted by both observational and theoretical results showing an increased abundance of low-i…
The THESAN-ZOOM project: Mystery N/O more -- uncovering the origin of peculiar chemical abundances and a not-so-fundamental metallicity relation at
William McClymont, Sandro Tacchella, Aaron Smith +15
We present an analysis of metallicities and chemical abundances at in the THESAN-ZOOM simulations. We find that smoothly curved gas-phase and stellar mass-metallicity rela…
Overmassive black holes in the early Universe can be explained by gas-rich, dark matter-dominated galaxies
William McClymont, Sandro Tacchella, Xihan Ji +12
JWST has revealed the apparent evolution of the black hole (BH)-stellar mass (-$M_\rm{\ast}$) relation in the early Universe, while remaining consistent with the BH-…
The THESAN-ZOOM project: Star formation efficiency from giant molecular clouds to galactic scale in high-redshift starbursts
Zihao Wang, Xuejian Shen, Mark Vogelsberger +12
Star formation in galaxies is inherently complex, involving the interplay of physical processes over a hierarchy of spatial scales. In this work, we investigate the connection betw…
The THESAN-ZOOM project: Star-formation efficiencies in high-redshift galaxies
Xuejian Shen, Rahul Kannan, Ewald Puchwein +10
Recent JWST observations hint at unexpectedly intense cosmic star-formation in the early Universe, often attributed to enhanced star-formation efficiencies (SFEs). Here, we analyze…
The THESAN-ZOOM project: central starbursts and inside-out quenching govern galaxy sizes in the early Universe
William McClymont, Sandro Tacchella, Aaron Smith +9
We explore the evolution of galaxy sizes at high redshift () using the high-resolution THESAN-ZOOM radiation-hydrodynamics simulations, focusing on the mass range of $1…
