Large-scale galaxy bias b_g,HOD as a functionof luminosity, with L^* as a reference point (left panel) and as a function of stellar mass with M^* as a reference point (right panel). In both plots, the coloured points indicate measurements at z ~ 3 from this work; the solid lines indicate the best-fit functions of the bias-luminosity dependence b_g,HOD(>L) (Eq. (13)) and bias-stellar mass dependence b_g,HOD(>M) (Eq. (14)) as described in Sect. 5.2. In the left panel, the black circles show the results from Zehavi et al. (2011) at z ~ 0 and the dashed line represents the empirical fit of the bias-luminosity dependence in the functional form given therein. In the right panel, we show for comparison the b_g measurements at z ~ 0.5 from Skibba et al. (2015) represented by open circles, those at z ~ 1 by Mostek et al. (2013) are indicated by black triangles and from different samples in the redshift range 0.5 < z < 2.5 measured by McCracken et al. (2015) shown as black lines as labelled.
