RIGEL: Feedback-regulated cloud-scale star formation efficiency in a simulated dwarf galaxy merger
Yunwei Deng, Hui Li, Federico Marinacci +5
Major mergers of galaxies are likely to trigger bursty star formation activities. The accumulation of dense gas and the boost of star formation efficiency (SFE) are considered to b…
Modelling the nebular emission of galaxies across cosmic time with COLT
William McClymont, Aaron Smith, Sandro Tacchella
Extragalactic nebular emission has long been a workhorse probe of the processes driving galaxy evolution, but the richness of JWST spectroscopy has shifted the bottleneck from data…
Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift
Alex M. Garcia, Paul Torrey, Aniket Bhagwat +22
The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-…
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 Entangling of Supernova Feedback Impacts with Coarsening Simulation Resolution
Eric Zhang, Laura V. Sales, Thales A. Gutcke +11
It is often understood that supernova (SN) feedback in galaxies is responsible for regulating star formation (SF) and generating gaseous outflows. However, a detailed look at the s…
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…
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…
JWST ASPIRE: How Did Galaxies Complete Reionization? Evidence for Excess IGM Transmission around Emitters during Reionization
Koki Kakiichi, Xiangyu Jin, Feige Wang +23
The spatial correlation between galaxies and the Ly forest provides insights into how galaxies reionized the Universe. Here, we present initial results on the spatial cross-corr…
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…
The THESAN-ZOOM project: Population III star formation continues until the end of reionization
Oliver Zier, Rahul Kannan, Aaron Smith +8
Population III (Pop III) stars are the first stars in the Universe, forming from pristine, metal-free gas and marking the end of the cosmic dark ages. Their formation rate is expec…
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-…
