Stellar mass function, Φ, measurements (hatched regions) from HST (S+21; Stefanon et al. 2021), the COSMOS field (W+22; Weaver et al. 2023), and JWST (N-C+23; Navarro-Carrera et al. 2024) in three redshift bins: z ∼ 6 (left), 7 (middle), and 8 (right). The dashed lines show extrapolations to higher masses for the DAWN survey volume (calculated in the same way as in Fig. 7) assuming the corresponding literature Schechter function fits, and the accompanying shaded regions show estimated uncertainties. Upper limits for empty bins for the respective survey are indicated with horizontal lines. We note that due to the shallower IRAC data in EDF-S (see Table 2), the z ∼ 8 bin assumes a smaller effective area of 39 deg². The grey shaded regions indicate the theoretical upper limit of the SMF in each redshift bin based on the Despali et al. (2016) halo mass function when assuming a fixed baryon fraction of 0.018 as in Weaver et al. (2023).
