Eddington ratio (λ_edd) versus redshift for our sample. The color of the points indicates black hole mass (M_BH). We also include BLAGNs found in W. He et al. (2024) as crosses. Similarly as Figure 4, we show the lower-redshift AGNs from SDSS DR16 in different contours from Q. Wu & Y. Shen (2022). Points outlined in black are known LRDs from the literature; see Section 5.3.
