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…
