THESAN-HR: How does reionization impact early galaxy evolution?
Josh Borrow, Rahul Kannan, Enrico Garaldi +5
Early galaxies were the radiation source for reionization, with the photoheating feedback from the reionization process expected to reduce the efficiency of star formation in low m…
The MillenniumTNG Project: An improved two-halo model for the galaxy-halo connection of red and blue galaxies
Boryana Hadzhiyska, Daniel Eisenstein, Lars Hernquist +11
Approximate methods to populate dark matter halos with galaxies are of great utility to large galaxy surveys. However, the limitations of simple halo occupation models (HODs) precl…
The MillenniumTNG Project: Refining the one-halo model of red and blue galaxies at different redshifts
Boryana Hadzhiyska, Lars Hernquist, Daniel Eisenstein +11
Luminous red galaxies (LRGs) and blue star-forming emission-line galaxies (ELGs) are key tracers of large-scale structure used by cosmological surveys. Theoretical predictions for…
The THESAN project: Lyman-alpha emitter luminosity function calibration
Clara Xu, Aaron Smith, Josh Borrow +6
The observability of Lyman-alpha emitting galaxies (LAEs) during the Epoch of Reionization can provide a sensitive probe of the evolving neutral hydrogen gas distribution, thus set…
The MillenniumTNG Project: Semi-analytic galaxy formation models on the past lightcone
Monica Barrera, Volker Springel, Simon White +9
Upcoming large galaxy surveys will subject the standard cosmological model, CDM, to new precision tests. These can be tightened considerably if theoretical models of galaxy form…
The MillenniumTNG Project: Inferring cosmology from galaxy clustering with accelerated N-body scaling and subhalo abundance matching
Sergio Contreras, Raul E. Angulo, Volker Springel +11
We introduce a novel technique for constraining cosmological parameters and galaxy assembly bias using non-linear redshift-space clustering of galaxies. We scale cosmological N-bod…
The MillenniumTNG Project: The galaxy population at
Rahul Kannan, Volker Springel, Lars Hernquist +11
The early release science results from have yielded an unexpected abundance of high-redshift luminous galaxies that seems to be in tension with current theories of…
The MillenniumTNG Project: The large-scale clustering of galaxies
Sownak Bose, Boryana Hadzhiyska, Monica Barrera +9
Modern redshift surveys are tasked with mapping out the galaxy distribution over enormous distance scales. Existing hydrodynamical simulations, however, do not reach the volumes ne…
The MillenniumTNG Project: The hydrodynamical full physics simulation and a first look at its galaxy clusters
Ruediger Pakmor, Volker Springel, Jonathan P. Coles +12
Cosmological simulations are an important theoretical pillar for understanding nonlinear structure formation in our Universe and for relating it to observations on large scales. In…
The MillenniumTNG Project: High-precision predictions for matter clustering and halo statistics
César Hernández-Aguayo, Volker Springel, Rüdiger Pakmor +9
Cosmological inference with large galaxy surveys requires theoretical models that combine precise predictions for large-scale structure with robust and flexible galaxy formation mo…
Bridging the Gap between Cosmic Dawn and Reionization favors Faint Galaxies-dominated Models
Ankita Bera, Sultan Hassan, Aaron Smith +4
It has been claimed that traditional models struggle to explain the tentative detection of the 21\,cm absorption trough centered at measured by the EDGES collaboration. O…
Unifying Sunyaev-Zel'dovich and X-ray predictions from clusters to galaxy groups: the impact of X-ray mass estimates on the scaling relation
Ana-Roxana Pop, Lars Hernquist, Daisuke Nagai +7
One of the main limitations in precision cluster cosmology arises from systematic errors and uncertainties in estimating cluster masses. Using the Mock-X pipeline, we produce synth…
Sunyaev-Zel'dovich effect and X-ray scaling relations of galaxies, groups and clusters in the IllustrisTNG simulations
Ana-Roxana Pop, Lars Hernquist, Daisuke Nagai +8
Observable thermodynamical properties of the intracluster medium (ICM) reflect the complex interplay between AGN feedback and the gravitational collapse of haloes. Using the large…
An Effective Bias Expansion for 21 cm Cosmology in Redshift Space
Wenzer Qin, Katelin Schutz, Aaron Smith +4
A near-future detection of the 21cm signal from the epoch of reionization will provide unique opportunities to probe the underlying cosmology, provided that such cosmological infor…
The THESAN project: ionizing escape fractions of reionization-era galaxies
Jessica Y. -C. Yeh, Aaron Smith, Rahul Kannan +6
A fundamental requirement for reionizing the Universe is that a sufficient fraction of the ionizing photons emitted by galaxies successfully escapes into the intergalactic medium.…
