Astro Seminar Series - VIA ZOOM

Ananth Tenneti - I completed my PhD in Physics at Carnegie Mellon University in December 2016. I have studied intrinsic alignments of galaxies using cosmological hydrodynamical simulations. Intrinsic alignments are an important astrophysical systematic in the weak lensing analysis for upcoming surveys such as the LSST (Rubin) and Euclid. I am currently working on small-scale modelling of intrinsic alignments and baryonic feedback effects in preparation for the Euclid telescope mission. At WCA, I will be working on galaxy-galaxy lensing analysis for the Euclid mission using numerical simulations.

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.
