Exploring variation of double-peak broad-line profile in strongly variable AGNs
Jiancheng Wu, Qingwen Wu, Kaixing Lu +4
The geometry and kinematics of the broad-line region (BLR) in AGNs are still unclear, which is crucial for studying the physics and evolution of supermassive black holes (SMBHs) an…
