  • Galaxy assembly bias, the correlation between galaxy properties and halo properties at fixed halo mass, could be an important ingredient in halo-based modelling of galaxy clustering. We investigate the central galaxy assembly bias by studying the relation between various galaxy and halo properties in the Illustris hydrodynamic galaxy formation simulation. Galaxy stellar mass $M_{star}$ is found to have a tighter correlation with peak maximum halo circular velocity $V_{peak}$ than with halo mass… CONTINUE READING
