MultiDark-Galaxies: data release and first results
Knebe et al
Planck Cosmology MultiDark sims, applying SAMs GALACTICUS, SAG, and SAGE. volume of 1 (Gpc/h)^3 and mass resolution of 1.5e9 Msun/h. Compare models with observation for: stellar mass function, SFR, cold gas fractions, and metallicities. Selected galaxy subsamples of catalogues by number densities in stellar mass, cold gas mass, and SFR in order to study the clustering statistics of galaxies. Show that despite different treatment of orphan galaxies (galaxies that lost their DM host halo due to the finite mass resolution of the N-body sim or tidal stripping) the clustering signal is comparable, and reproduces the observations in all 3 models - in particular when selecting samples based upon stellar mass. The catalogues provide a powerful tool to study galaxy formation within a volume comparable to those probed by on-going and future photometric and z surveys. All model data consisting of a range of galaxy properties - including broad-band SDSS magnitudes - are publicly available.
