Galaxy bias as a function of redshift and M_UV. The empty circles with error bars show the bias for the three line emitter samples Hα at z ∼ 4.3 and 5.4, and [O III] at z ∼ 7.3 with M_UV < −19.1 mag. The solid blue lines show the bias as a function of redshift for four M_UV thresholds computed from our model. We compare with measurements from Harikane et al. (2016), Dalmasso et al. (2024b) and Dalmasso et al. (2024a) for photometrically selected LBG, as well as Paquereau et al. (2025) for stellar mass selected, normal galaxies.
