Galaxies

Most simulations published here do not take hydrodynamics and star formation into account. However, given a catalog of dark matter halos and their merging histories, it is possible to compute properties of galaxies that would reside in these dark matter halos using semi-analytical recipes.

Within the CosmoSim database, you can find data from following semi-analytical codes:

• Galacticus: Benson 2012, MDPL2 Galacticus
• SAGE: Croton, D.J. et al., 2016, MDPL2 SAGE table
• SAG: Cora, S.A. et al., 2018, MDPL2 SAG table

MDPL2 galaxies

Currently CosmoSim has galaxy properties for the MDPL2 simulation.
These tables are based on the mdpl2.rockstar dark matter halo catalog and the merger tree information there.

• MDPL2 Galacticus
• MDPL2 SAGE
• MDPL2 SAG
