Redshift evolution of linear galaxy bias. The early prediction from Tegmark & Peebles (1998) is shown in solid grey, and more recent models separated by stellar mass from Moster et al. (2010) are shown as dashed grey curves. High-z measurements for dropout-selected samples from Beck et al. (2020) and Harikane et al. (2022) are shown in red and green, respectively. Low-z measurements for two stellar masses from Ishikawa et al. (2020) are shown in blue and purple. The DAWN survey will allow us to constrain bias as a function of redshift and stellar mass in the shaded region.
