The THESAN project: connecting ionized bubble sizes to their local environments during the Epoch of Reionization
Meredith Neyer, Aaron Smith, Rahul Kannan +7
An important characteristic of cosmic hydrogen reionization is the growth of ionized gas bubbles surrounding early luminous objects. Ionized bubble sizes are beginning to be probed…
Statistics of thermal gas pressure as a probe of cosmology and galaxy formation
Ziyang Chen, Drew Jamieson, Eiichiro Komatsu +8
The statistics of thermal gas pressure are a new and promising probe of cosmology and astrophysics. The large-scale cross-correlation between galaxies and the thermal Sunyaev-Zeldo…
Simulating ionization feedback from young massive stars: impact of numerical resolution
Yunwei Deng, Hui Li, Rahul Kannan +3
Modelling galaxy formation in hydrodynamic simulations has increasingly adopted various radiative transfer methods to account for photoionization feedback from young massive stars.…
Evolution of cosmic filaments in the MTNG simulation
Daniela Galárraga-Espinosa, Corentin Cadiou, Céline Gouin +11
We present a study of the evolution of cosmic filaments across redshift with an emphasis on some important properties: filament lengths, growth rates, and radial profiles of galaxy…
The thesan project: public data release of radiation-hydrodynamic simulations matching reionization-era JWST observations
Enrico Garaldi, Rahul Kannan, Aaron Smith +13
Cosmological simulations serve as invaluable tools for understanding the Universe. However, the technical complexity and substantial computational resources required to generate su…
The impact of UV variability on the abundance of bright galaxies at
Xuejian Shen, Mark Vogelsberger, Michael Boylan-Kolchin +2
JWST observations have revealed a population of galaxies bright enough that potentially challenge standard galaxy formation models in the CDM cosmology. Using a minimal empirica…
Interpreting Sunyaev-Zel'dovich observations with MillenniumTNG: Mass and environment scaling relations
Boryana Hadzhiyska, Simone Ferraro, Rüdiger Pakmor +7
In the coming years, Sunyaev-Zel'dovich (SZ) measurements can dramatically improve our understanding of the Intergalactic Medium (IGM) and the role of feedback processes on galaxy…
THESAN-HR: Galaxies in the Epoch of Reionization in warm dark matter, fuzzy dark matter and interacting dark matter
Xuejian Shen, Josh Borrow, Mark Vogelsberger +8
Using high-resolution cosmological radiation-hydrodynamic (RHD) simulations (THESAN-HR), we explore the impact of alternative dark matter (altDM) models on galaxies during the Epoc…
The MillenniumTNG Project: Intrinsic alignments of galaxies and halos
Ana Maria Delgado, Boryana Hadzhiyska, Sownak Bose +9
The intrinsic alignment (IA) of observed galaxy shapes with the underlying cosmic web is a source of contamination in weak lensing surveys. Sensitive methods to identify the IA sig…
