Cartoon showing the methodology used to form and evolve galaxies in DECODE. The SFR-HAR relation at each redshift is computed via abundance matching between the observed SFR function and HAR function from simulations. SFRs are assigned to galaxies following the accretion rate history of their dark matter haloes. We drop the SFR instantaneously when the galaxy is quenched. Galaxy stellar mass growths are constructed by integrating the SFR and quenching the star formation via the mechanism we are testing. Finally, we make our predictions on the SMHM relation, SMF, and quiescent fraction, and compare them with the observations.
