Black hole mass (M_BH) versus bolometric luminosity (L_bol) for our AGN sample. The color of the points indicates redshift. Symbols indicate AGNs from this study (⋆), C. J. Willott et al. (2010) z ≈ 6) (■), H. Übler et al. (2023) z ∼ 5.5) (•), M. Onoue et al. (2019) 6.1 ≤ z ≤ 6.7 (▾), Y. Shen et al. (2019) z ≥ 5.7(▴), X. Lin et al. (2024) 4 ≤ z ≤ 5 (▸), J. E. Greene et al. (2024) z ≥ 5 (⬠), R. Maiolino et al. (2024) 4 ≤ z ≤ 11 (+), Y. Harikane et al. (2023) 4 ≤ z ≤ 7 (×). Light-gray points are studies from which the redshift of the objects is not provided. Contours show low-z AGNs from redshifts 1–2 from SDSS DR16 (Q. Wu & Y. Shen 2022), and the dashed lines show the Eddington ratio (λ_edd) of 0.01, 0.1, and 1. Points outlined in black are known LRDs from the literature; see Section 5.3.
