The effect of baryons on the positions and velocities of satellite galaxies in the MTNG simulation
Sergio Contreras, Raul E. Angulo, Sownak Bose +5
Mock galaxy catalogues are often constructed from dark-matter-only simulations based on the galaxy-halo connection. Although modern mocks can reproduce galaxy clustering to some ex…

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…

The origin of lopsided satellite galaxy distribution around isolated systems in MillenniumTNG
Yikai Liu, Peng Wang, Hong Guo +4
Dwarf satellites in galaxy groups are distributed in an anisotropic and asymmetric manner, which is called the ``lopsided satellite distribution''. This lopsided signal has been ob…
