Measurements of the SMF and its evolution with redshift in COSMOS-Web. Each panel shows the SMF in a given redshift bin, along with measurements in the literature from Weaver et al. (2022), Davidzon et al. (2017), Stefanon et al. (2021), Navarro-Carrera et al. (2023), Weibel et al. (2024), Harvey et al. (2025). The upper limits for empty bins are shown for the COSMOS-Web volume. In each z bin, we show the functional form that fits best the data (lowest Bayesian information criterion), while at z > 4.5, we show both the single Schechter and DPL fits for illustration. We plot the functions convolved with the Eddington bias kernel.
