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…
A lensed radio jet at milli-arcsecond resolution II: Constraints on fuzzy dark matter from an extended gravitational arc
Devon M. Powell, Simona Vegetti, J. P. McKean +4
Using a single gravitational lens system observed at milli-arcsecond resolution with very long baseline interferometry (VLBI), we place a lower bound on the mass of the…
The effect of stellar encounters on the dark matter annihilation signal from prompt cusps
Jens Stücker, Go Ogiya, Simon D. M. White +1
Prompt cusps are the densest quasi-equilibrium dark matter objects; one forms at the instant of collapse within every isolated peak of the initial cosmological density field. They…
Consistent and simultaneous modelling of galaxy clustering and galaxy-galaxy lensing with Subhalo Abundance Matching
Sergio Contreras, Raul E. Angulo, Jonás Chaves-Montero +2
The spatial distribution of galaxies and their gravitational lensing signal offer complementary tests of galaxy formation physics and cosmology. However, their synergy can only be…
