Notes. These best-fit parameters were obtained by Araya-Araya et al. (2025) for the no HIMF model, which obtains a good match to the S870 number counts while remaining consistent with observationally derived lower limits on the number density of high-redshift massive quiescent galaxies. The model was calibrated using the MCMC mode of L-Galaxies. The observational constraints were the stellar mass function and fraction of quiescent (sSFR ≤ 10−11 yr−1) galaxies as a function of stellar mass at z = 0.4 and z = 2.8 (Leja et al. 2020, 2022), and the number density of bright (S870 ≥ 5.2 mJy) sub-millimetre galaxies at z = 2.8 (Dudzevičiūtė et al. 2020). Full details of these parameters and their corresponding equations are given in the Supplementary Material of Henriques et al. (2020).
