Growth of the black hole mass as a function of redshift (or cosmic time). Assuming seeding at a redshift of z_seed = 25, we show the black hole growth considering both Eddington-limited (f_Edd = 1) and super-Eddington (f_Edd > 1) accretion for seed masses of 100, 10⁴, and 10⁵ M_⊙, as marked. As detailed in Table 1 and marked in the plot, we compare these models to black holes confirmed by Bogdán et al. (2024), Furtak et al. (2024), Kocevski et al. (2023), Maiolino et al. (2024a,b), Harikane et al. (2023), Greene et al. (2024), Kokorev et al. (2023), Kovács et al. (2024), and Juodžbalis et al. (2024).
