Γ vs. λ_Edd for our sample of z > 6 QSOs (red stars) compared with the WISSH sample of QSOs at z = 2 − 4 (green diamonds, Zappacosta et al. 2020), the SDSS DR7 blue QSOs at z ≃ 3.0 − 3.3 (blue inverted triangles, Trefoloni et al. 2023), local hyper-Eddington AGN (orange triangles, Tortosa et al. 2023), radio-quiet super-Eddington accreting QSOs at 0.4 ≤ z ≤ 0.75 (purple, pentagons Laurenti et al. 2022), a sample of z < 0.4 AGN (yellow circles, Liu et al. 2021) and the local type 1 AGN belonging to the BASS sample (grey points, Trakhtenbrot et al. 2017; Ricci et al. 2017). We also report the linear relations from Trakhtenbrot et al. 2017 (grey dashed line), Liu et al. 2021 (yellow dot-dashed line) and Tortosa et al. 2023 (orange dotted line).
