The Most Luminous Hβ Reverberation Mapping of E1821+643 Indicates the Lower Boundary of the Radius–Luminosity Relation

The radius–luminosity ( R _BLR –L _5100 ) relation is fundamental to active galactic nucleus (AGN) studies, enabling supermassive black hole (SMBH) mass estimates and AGN-based cosmology applications. However, its high-luminosity end remains poorly calibrated due to insufficient reliable reverberati...
