Ultraviolet magnitude (M_UV) as a function of M_h at z = 9 within different models. The relation in this work is obtained via a fit of the LF (see Eq. 4 for the functional form and Eq. 5 for the parameters). For comparison, we report M_UV(M_h) from the semi-analytical model of Ferrara et al. (2023, in the dust-attenuated, DA, and attenuation-free, AF, cases), from the abundance-matching based procedure of Behroozi et al. (2019) and results from the BlueTides hydrodynamical simulations (Wilkins et al. 2017).
