SatGen: Semi-analytical satellite galaxy and dark matter halo generator
Jiang, Fangzhou; Dekel, Avishai; Freundlich, Jonathan; van den Bosch, Frank C.; Green, Sheridan B.; Hopkins, Philip F.; Benson, Andrew; Du, Xiaolong
SatGen generates satellite-galaxy populations for host halos of desired mass and redshift. It combines halo merger trees, empirical relations for galaxy-halo connection, and analytic prescriptions for tidal effects, dynamical friction, and ram-pressure stripping. It emulates zoom-in cosmological hydrosimulations in certain ways and outperforms simulations regarding statistical power and numerical resolution.
