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 Lumina Project: Morphology of Ionized Bubbles and Neutral Islands
Meredith Neyer, Aaron Smith, Ali Sadain +10
The Epoch of Reionization is characterized by the nucleation, expansion, and percolation of ionized bubbles in the intergalactic medium. Interpreting emerging multi-wavelength obse…
RIGEL: Ultra-faint dwarf galaxy diversity shaped by inhomogeneous cosmic reionization
Yunwei Deng, Hui Li, Ewald Puchwein +7
Ultra-faint dwarf galaxies (UFDs) are among the smallest and oldest galaxies in the Universe and are widely regarded as relics of cosmic reionization. To investigate how reionizati…
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,…
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…
A framework for modelling Population III stars in cosmological simulations
Bipradeep Saha, Rahul Kannan, Giovanni M. Mirouh
Population III (Pop III) stars are the first generation of stars to form in the universe, emerging from primordial gas composed mainly of hydrogen and helium. They play a crucial r…
The Lumina Project: The Demographics of Active Galactic Nuclei from Quasars to Little Red Dots at
Xuejian Shen, Oliver Zier, Aaron Smith +16
High-redshift active galactic nuclei (AGN) serve as powerful probes of early black-hole growth, galaxy formation, and the evolving intergalactic medium (IGM). In this work, we use…
The Lumina Project: CMB Optical Depth Fluctuations from Patchy Reionization
Aaron Smith, Oliver Zier, Rahul Kannan +8
Patchy reionization couples the ionized-bubble morphology to the underlying density field, making the CMB Thomson optical depth sensitive to both the global ionization history and…
Introducing the Lumina project: large-volume radiation-hydrodynamic simulations of the epochs of hydrogen and helium reionization
Oliver Zier, Aaron Smith, Xuejian Shen +8
Understanding how galaxies and active galactic nuclei (AGN) jointly drive the reionization of the intergalactic medium (IGM) across cosmic time remains a major challenge in cosmolo…
Identifying signatures of inflow onto face-on galaxies using the Balmer decrement
Meghna Sitaram, Hui Li, Yong Zheng +4
Isolated star-forming galaxies require inflows of fresh gas from the surrounding medium to sustain episodes of star formation over time. However, there are very few direct detectio…
