Modelling galaxy stellar mass evolution from z~0.8 to today

Understand

We apply the empirical method built for z=0 in the previous work of Wang et al.

• to a higher redshift, to link galaxy stellar mass directly with its hosting dark matter halo mass at z~0.8.
• The relation of the galaxy stellar mass and the host halo mass M_infall is constrained by fitting both the stellar mass function and the correlation functions at different stellar mass intervals of the VVDS observation, where M_infall is the mass of the hosting halo at the time when the galaxy was last the central galaxy.
• We find that for low mass haloes, their residing central galaxies are less massive at high redshift than those at low redshift.
