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…
