Measurements of the UV luminosity function ϕ at z = 8–10 from the literature (Oesch et al. 2018; Bowler et al. 2020; Bouwens et al. 2021; Finkelstein & Bagley 2022; Adams et al. 2024; Donnan et al. 2023). The red and blue lines show extrapolations to the volume of the DAWN survey based on the best-fitting Schechter and double power-law (DPL) functions, with the shaded regions showing associated Poisson uncertainties for the DAWN survey volume. Upper limits based on survey volume are indicated with the horizontal lines. The DAWN volume in each panel assumes an area of 59 deg², a redshift slice of ±0.5 from the redshift bin centre, and a Planck Collaboration VI (2020)ΛCDM cosmology.
