UV luminosity functions at redshift z = 11, z = 15, z = 17 (left and right panels), and z = 25 (right panel). Solid lines represent our median predictions (galaxies plus PBH emission) with credible intervals at the 16th and 84th percentiles shown as shaded areas. Dashed lines show the AFM results (Ferrara et al. 2023) for galaxies only. Red hexagons denote z = 17 and 25 observations from Pérez-González et al. (2025); other points represent data in the range 11 ≤ z ≤ 19 from Donnan et al. (2024), McLeod et al. (2024), Robertson et al. (2024), Morishita et al. (2025), Harikane et al. (2024), Kokorev et al. (2025), Yan et al. (2023), Whitler et al. (2025).
