Bolometric luminosities vs. Mg II black hole masses of seven quasars reported in this paper. We also show z≥6 quasars from the literature (dark blue dots; Fan et al. 2023; Mazzucchelli et al. 2023) and quasars at 0.35 <z< 2.25 from the SDSS DR16 catalog (gray contours and gray points; Wu & Shen 2022). The dotted black lines show the location of a constant accretion rate at 0.01, 0.1, and 1 times the Eddington luminosity. Our quasars reside in the same parameter space as the population of z>6 quasars.
