The THESAN project: tracking the expansion and merger histories of ionized bubbles during the Epoch of Reionization
Nathan Jamieson, Aaron Smith, Meredith Neyer +7
The growth of ionized hydrogen bubbles in the intergalactic medium around early luminous objects is a fundamental process during the Epoch of Reionization (EoR). In this study, we…
The galaxy-IGM connection in THESAN: observability and information content of the galaxy-Lyman- cross-correlation at z6
Enrico Garaldi, Verena Bellscheidt, Aaron Smith +1
The galaxy--Lyman- cross-correlation (GaLaCC) is a promising tool to study the interplay of galaxies and inter-galactic medium (IGM) in the first billion years of the Universe.…
How Early Could the Milky Way's Disk Form?
Vadim A. Semenov, Charlie Conroy, Aaron Smith +2
We investigate early, , galaxy formation in a cosmological zoom-in simulation of a close, early-forming Milky Way (MW) analog extracted from TNG50 simulation and resimulated…
The density-bounded twilight of starbursts in the early Universe
William McClymont, Sandro Tacchella, Francesco D'Eugenio +8
The peculiar nebular emission displayed by galaxies in the early Universe presents a unique opportunity to gain insight into the regulation of star formation in extreme environment…
RIGEL: Simulating dwarf galaxies at solar mass resolution with radiative transfer and feedback from individual massive stars
Yunwei Deng, Hui Li, Boyuan Liu +3
We introduce the RIGEL model, a novel framework to self-consistently model the effects of stellar feedback in the multiphase ISM of dwarf galaxies with radiative transfer (RT) on a…
Adapting AREPO-RT for Exascale Computing: GPU Acceleration and Efficient Communication
Oliver Zier, Rahul Kannan, Aaron Smith +2
Radiative transfer (RT) is a crucial ingredient for self-consistent modelling of numerous astrophysical phenomena across cosmic history. However, on-the-fly integration into radiat…
The nature of diffuse ionised gas in star-forming galaxies
William McClymont, Sandro Tacchella, Aaron Smith +6
We present an analysis of the diffuse ionised gas (DIG) in a high-resolution simulation of an isolated Milky Way-like galaxy, incorporating on-the-fly radiative transfer and non-eq…
The THESAN project: galaxy sizes during the epoch of reionization
Xuejian Shen, Mark Vogelsberger, Josh Borrow +12
We investigate galaxy sizes at redshift with the cosmological radiation-magneto-hydrodynamic simulation suite THESAN(-HR). These simulations simultaneously capture the…
