The Connection between Galaxy Growth and Dark Matter Halo Assembly from z=0–10


We present a short review of the connection between galaxies and dark matter halos, followed by a new method to flexibly and self-consistently infer individual galaxies' star formation rates as a function of their host halos' potential well depths, assembly histories, and redshifts. The method is able to match galaxies' observed stellar mass functions, star formation rates (specific and cosmic), quenched fractions, UV luminosity functions, autocorrelation functions and lensing shear (including for quenched and star-forming subsamples), and quenching dependence on environment; each observable is reproduced over the full redshift range available, up to 0<z<10. We discuss physical implications for galaxy quenching, the connection between halo and galaxy assembly, revised stellar mass-halo mass relations, and predictions for higher-redshift galaxy correlation functions and weak lensing signals.
