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…
Simulations on the collision between debris stream and outer dusty torus: a possible channel for forming fast-rise and long-delayed radio outburst in tidal disruption events
Xiangli Lei, Qingwen Wu, Hui Li +6
The geometrically thick dusty torus structure is believed to exist in the nuclear region of galaxies (especially in active galactic nuclei, AGNs). The debris stream from a tidal di…
The Interaction Between Stars and Past AGN Disk: Possible Explanation for the Kinematic Distributions of S-stars in the Galactic Center
Xiao Fan, Qingwen Wu, Jiancheng Wu +3
The presence of young stars, aged around several million years and situated within the range of pc from our Galactic center raises a question about their origins and…
The weakness of soft X-ray intensity: possible physical reason for weak line quasars
Jiancheng Wu, Qingwen Wu, Chichuan Jin +8
Weak-line quasars (WLQs) are a notable group of active galactic nuclei (AGNs) that show unusually weak UV lines even though their optical-UV continuum shapes are similar to those o…
