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…
Self-Interacting Dark Matter: From Particle Physics Theories to Structure Formation Simulations
Martin Rosenlyst, Vinh Tran, Oliver Zier +7
We establish a unified theory-to-simulation framework for self-interacting dark matter (SIDM) that integrates three components: (i) a comprehensive, self-contained treatment of its…
Weighing Little Red Dots with Transient Events
Vinh Tran, Xuejian Shen, Oliver Zier +3
Recent JWST observations have revealed a large population of compact red sources at , known as Little Red Dots (LRDs), many of which show signatures of accreting massi…
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…
What becomes of JWST/NIRCam-selected high-redshift massive galaxies?
Devontae C. Baxter, Alison L. Coil, Ethan O Nadler +2
Early JWST/NIRCam surveys revealed a puzzling population of high-redshift massive galaxy candidates largely absent from previous rest-frame UV surveys. Spectroscopic follow-up has…
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,…
A Novel Implementation of Self-Interacting Dark Matter in AREPO
Oliver Zier, Xuejian Shen, Vinh Tran +3
Self-interacting dark matter (SIDM) influences halo structure through collisional heat transport and may solve several small-scale puzzles in structure formation. SIDM creates ther…
A Universal Dance of Galactic Disks: Ubiquitous Precession and Its Implications
Yuan Wang, Xiong Luo, Huiyuan Wang +5
Precession is a very common phenomenon for small-scale astronomical objects. However, the precession of galactic disks, occurring on a scale larger than kilo-parsec, has barely bee…
The Lumina Project: Intergalactic Clumping and Recombination Sinks
Ali Sadain, Aaron Smith, Oliver Zier +10
Recombinations during the Epoch of Reionization are intrinsically inhomogeneous, with different regions of the intergalactic medium contributing unevenly depending on their density…
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…
