  We present the public release of the MultiDark-Galaxies: three distinct
galaxy catalogues derived from one of the Planck cosmology MultiDark
simulations (i.e. MDPL2, with a volume of (1 Gpc/$h$)$^{3}$ and mass resolution
of $1.5 \times 10^{9} M_{\odot}/h$) by applying the semi-analytic models
GALACTICUS, SAG, and SAGE to it. We compare the three models and their
conformity with observational data for a selection of fundamental properties of
galaxies like stellar mass function, star formation rate, cold gas fractions,
and metallicities - noting that they sometimes perform differently reflecting
model designs and calibrations. We have further selected galaxy subsamples of
the catalogues by number densities in stellar mass, cold gas mass, and star
formation rate in order to study the clustering statistics of galaxies. We show
that despite different treatment of orphan galaxies, i.e. galaxies that lost
their dark-matter host halo due to the finite mass resolution of the N-body
simulation or tidal stripping, the clustering signal is comparable, and
reproduces the observations in all three models - in particular when selecting
samples based upon stellar mass. Our catalogues provide a powerful tool to
study galaxy formation within a volume comparable to those probed by on-going
and future photometric and redshift surveys. All model data consisting of a
range of galaxy properties - including broad-band SDSS magnitudes - are
publicly available.
