The THESAN-ZOOM project: the delayed rise of Lyman continuum escape fractions in bursty high-redshift galaxies
Parth Mehrotra, Aaron Smith, Yuan Bian +13
The ionizing radiation that galaxies release into their surroundings depends on whether efficient Lyman continuum (LyC) escape coincides with strong photon production. Stellar feed…
The THESAN-ZOOM project: clumpiness of high-redshift galaxies and its connection to bursty star formation
Zihao Wang, Xuejian Shen, Rahul Kannan +12
Recent JWST observations have revealed diverse high-redshift galaxy morphologies, including a population with irregular and clumpy structures. The physical origin of these structur…
The Thesan-Zoom project: bursty star formation is incompatible with prolonged dust survival
Enrico Garaldi, Filip Popovic, Rahul Kannan +11
Cosmic dust is a key regulator of galaxy evolution, but its build-up and survival in the first billion years remain poorly constrained. We present a systematic analysis of dust in…
Globular cluster abundance patterns inherited from giant molecular clouds
William McClymont, Vasily Belokurov, Sandro Tacchella +16
Globular clusters exhibit large star-to-star variations and anticorrelations in their light element abundances that are commonly interpreted in terms of in-cluster self-enrichment,…
From THESAN-ZOOM to JWST: Predicting ionizing photon escape and the rise of UV-bright reionization sources
Zebedee Summerfield, William McClymont, Sandro Tacchella +14
Understanding the sources and evolution of cosmic reionization remains a central challenge in astrophysics, with the escape of ionizing Lyman-continuum (LyC) photons from early gal…
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 project: Lyman-alpha emitters as probes of ionized bubble sizes
Meredith Neyer, Aaron Smith, Mark Vogelsberger +4
We use the THESAN radiation-hydrodynamics simulations to investigate how Lyman- emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization. We generate realisti…
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…
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-…
