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:

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 therein.
