Talk Title and Abstract
Intrinsic alignments of galaxies in hydrodynamical simulations
The intrinsic alignments of galaxies is an important astrophysical systematic in upcoming weak gravitational lensing surveys such as LSST (Rubin) and Euclid. I will present results on the measurements of intrinsic alignments and their dependence on galaxy properties such as mass, luminosity and morphology in the hydrodynamical simulations, MassiveBlack-II and Illustris-TNG. I will also discuss small-scale galaxy alignments in these simulations – radial alignment and the anisotropic distribution of satellite galaxies.
