Numerical effects on the stripping of dark matter and stars in IllustrisTNG galaxy groups and clusters
Mark R. Lovell, Annalisa Pillepich, Christoph Engler +4
The stellar haloes and intra-cluster light around galaxies are crucial test beds for dark matter (DM) physics and galaxy formation models. We consider the role that the numerical r…

The multi-wavelength Tully-Fisher relation in the TNG50 cosmological simulation
Maarten Baes, Andrea Gebek, Sabelo Kunene +8
The Tully-Fisher relation (TFR) is one of the most important and widely used empirical correlations in extragalactic astronomy. Apart from its importance as a secondary distance in…

Tracing the cosmological origin of gas that fuels in situ star formation in TNG50 galaxies
Ole Wittig, Rahul Ramesh, Dylan Nelson
Based on their cosmological origin, the stars of a galaxy can be divided into two categories: those that enter through merger events (ex situ) and those born in the main progenitor…
