as a function of M_UV (top) and UV slope (bottom). The VANDELS objects are color-coded according to the relevant redshift. The empty and filled black squares and error bars show the average and standard deviation for the entire sample and for galaxies with log(M_star/M_⊙) > 9.5, respectively. The VANDELS sample is compared to measurements from the literature by Shivaei et al. (2018; LBGs at z ∼ 2 − 3), Emami et al. (2020; lensed dwarf galaxies at 1.4 < z < 2.7), and Bouwens et al. (2016) and Lam et al. (2019; LBGs at z ∼ 4 − 5). See the legend for symbols and colors. The continuous black lines show the relations measured by Prieto-Lyon et al. (2023) on sub-L^* galaxies at z ∼ 3 − 7.
