Ray-tracing vs. Born approximation in full-sky weak lensing simulations of the MillenniumTNG project
Fulvio Ferlito, Christopher T. Davies, Volker Springel +7
Weak gravitational lensing is a powerful tool for precision tests of cosmology. As the expected deflection angles are small, predictions based on non-linear N-body simulations are…
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…
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…
An emulator-based halo model in modified gravity -- I. The halo concentration-mass relation and density profile
Cheng-Zong Ruan, Carolina Cuesta-Lazaro, Alexander Eggemeier +7
In this series of papers we present an emulator-based halo model for the non-linear clustering of galaxies in modified gravity cosmologies. In the first paper, we present emulators…
Euclid: Modelling massive neutrinos in cosmology -- a code comparison
J. Adamek, R. E. Angulo, C. Arnold +133
The measurement of the absolute neutrino mass scale from cosmological large-scale clustering data is one of the key science goals of the Euclid mission. Such a measurement relies o…
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 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…
The Uchuu-SDSS galaxy lightcones: a clustering, RSD and BAO study
C. A. Dong-Páez, A. Smith, A. O. Szewciw +11
We present the data release of the Uchuu-SDSS galaxies: a set of 32 high-fidelity galaxy lightcones constructed from the large Uchuu 2.1 trillion particle -body simulation using…
A general framework to test gravity using galaxy clusters IV: Cluster and halo properties in DGP gravity
Myles A. Mitchell, César Hernández-Aguayo, Christian Arnold +1
We study and model the properties of galaxy clusters in the normal-branch Dvali-Gabadadze-Porrati (nDGP) model of gravity, which is representative of a wide class of theories which…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at , when D…
