Evolution of σ_UV with the redshift for our sample in JADES at 6 < z < 12. The uncertainties on σ_UV are estimated from bootstrapping. The error bar on redshifts indicates the 16^th to 84^th percentiles of the distributions. The blue shades and markers show estimations from the literature, which are based on semi-analytical models and simulations (Pallottini & Ferrara 2023; Shen et al. 2023; Muñoz et al. 2023; Mason et al. 2023) or observations (Ciesla et al. 2024; Shuntov et al. 2025a). Our estimate σ_UV is consistent with the literature and too low to explain the mild evolution of the UVLF at z > 10 only from bursty SFH, as estimated by Shen et al. (2023) (empty circles) using empirical models.
