Some Progress on Galaxy-Halo Connection

This astrophysics seminar explores advances in understanding the galaxy-halo connection, presented by Yen-Ting Lin from the Institute for Advanced Study. Delve into four key research developments: the detection of assembly bias signal using constrained simulation Elucid, a graphic neural network model that predicts stellar mass and galaxy color at redshifts z=0-5 based on dark matter subhalo properties, a novel approach to studying the redshift evolution of the stellar mass-halo mass relation, and a unique method for estimating host halo mass by counting neighboring galaxies. Learn about the complex relationship between galaxies and their host dark matter halos in this comprehensive hour-long presentation from the Institute for Advanced Study Astrophysics Seminar series.
