Left: L_{2 − 10 keV} − L_Hα relation; Right: L_{2 − 10 keV}/L_Hα − λ_Edd relation. We report: the BASS sample (blue crosses, Gupta et al. 2024), the SDSSDR16–4XMM sample (magenta crosses, Wu & Shen 2022) and NLS1 sample (cyan crosses, Jin et al. 2012b). Red circles are the upper limits of LRDs from Yue et al. (2024) derived assuming N_H = 10²¹ cm⁻². Orange circles are the upper limits of JWST-selected AGN from Maiolino et al. (2025). Yellow squares are the SEAMBHs from Tortosa et al. (2023). The dashed cyan line marks the best fit linear relation from Jin et al. (2012b) respectively. White circles with red edges are the low-z LRDs analogues from Lin et al. (2026). We report also the 1 − 2 − 3σ contour levels (relative to the peak) for the low-redshift type I AGN.
