The Millennium and Astrid galaxies in effective field theory: comparison with galaxy-halo connection models at the field level
Mikhail M. Ivanov, Carolina Cuesta-Lazaro, Andrej Obuljen +8
Cosmological analyses of redshift space clustering data are primarily based on using luminous ``red'' galaxies (LRGs) and ``blue'' emission line galaxies (ELGs) to trace underlying…
Investigating cosmic strings using large-volume hydrodynamical simulations in the context of JWST's massive UV-bright galaxies
Sonja M. Koehler, Hao Jiao, Rahul Kannan
Recent observations from the James Webb Space Telescope (JWST) have uncovered an unexpectedly large abundance of massive, UV-bright galaxies at high redshifts, presenting a signifi…
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: the physics connecting the IGM Lyman- opacity and galaxy density in the reionization epoch
Enrico Garaldi, Verena Bellscheidt, A. Smith +1
The relation between the Lyman- effective optical depth of quasar sightlines () and the distribution of galaxies around them is an emerging probe of the connecti…
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.…
The impact of baryons on the internal structure of dark matter haloes from dwarf galaxies to superclusters in the redshift range 0<z<7
Daniele Sorini, Sownak Bose, Rüdiger Pakmor +5
We investigate the redshift evolution of the concentration-mass relationship of dark matter haloes in state-of-the-art cosmological hydrodynamic simulations and their dark-matter-o…
The MillenniumTNG Project: Impact of massive neutrinos on the cosmic large-scale structure and the distribution of galaxies
César Hernández-Aguayo, Volker Springel, Sownak Bose +10
We discuss the cold dark matter plus massive neutrinos simulations of the MillenniumTNG (MTNG) project, which aim to improve understanding of how well ongoing and future large-scal…
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 boundary of cosmic filaments
Wei Wang, Peng Wang, Hong Guo +12
For decades, the boundary of cosmic filaments have been a subject of debate. In this work, we determine the physically-motivated radii of filaments by constructing stacked galaxy n…
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…
Brightest Cluster Galaxy Offsets in Cold Dark Matter
Cian Roche, Michael McDonald, Josh Borrow +7
The distribution of offsets between the brightest cluster galaxies of galaxy clusters and the centroid of their dark matter distributions is a promising probe of the underlying dar…
