Estimating the triaxiality of massive clusters from 2D observables in MillenniumTNG with machine learning
Ana Maria Delgado, Michelle Ntampaka, Sownak Bose +7
Properties of massive galaxy clusters, such as mass abundance and concentration, are sensitive to cosmology, making cluster statistics a powerful tool for cosmological studies. How…
Fully non-linear simulations of galaxy intrinsic alignments for weak lensing with the MillenniumTNG lightcone
Fulvio Ferlito, Volker Springel, Christopher T. Davies +4
We present a complete forward model of a realistic weak lensing galaxy catalogue based on the 740 Mpc hydrodynamical MillenniumTNG (MTNG) simulation. Starting with a complete parti…
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…
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…
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 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…
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…
Cosmological direct detection of dark energy: non-linear structure formation signatures of dark energy scattering with visible matter
Fulvio Ferlito, Sunny Vagnozzi, David F. Mota +1
We consider the recently proposed possibility that dark energy (DE) and baryons may scatter through a pure momentum exchange process, leaving the background evolution unaffected. E…
