Evolution of the UV luminosity function from z = 6 to z = 13. The cyan regions represent the FirstLight simulations with Poisson uncertainties. JWST observations are marked by blue circles (Harikane et al. 2023), blue squares (Finkelstein et al. 2024), red circles (Bouwens et al. 2022), and red squares (Yan et al. 2023). Pre-JWST observations are shown by black lines (Bouwens et al. 2021). The fiducial models by Ferrara et al. (2023) (grey dash-dotted line), Yung et al. (2023) (brown dashed lines), Mauerhofer & Dayal (2023) (brown dash-dotted lines), and Gelli et al. (2024) (gray dotted lines) fail to reproduce JWST observations at z ≥ 9. FirstLight results lie in between FFB models with ϵ_max = 0.2 and 1 (gray solid lines).
