Left panel: the SMF of QGs at 2 < z < 8, fitted with a single Schechter function. Galaxies with ﹩{\mathrm{log}}({M}_{\star }/{M}_{\odot })=9-9.5﹩ are included in the fit only in redshift bins where the sample is complete. Data points and the best-fit Schechter functions are shown. The fitting methodology follows the procedure described in H. Sun et al. (2024). Right panel: comparison of our observations with J. R. Weaver et al. (2023) and W. M. Baker et al. (2025b) in three redshift ranges: z ∼ 2–2.5, z ∼ 3–3.5, and z ∼ 4–5.
