The Most Luminous H Reverberation Mapping of E1821+643 Indicates the Lower Boundary of the Radius-Luminosity Relation
Sha-Sha Li, Hai-Cheng Feng, Jiancheng Wu +5
The radius-luminosity (-) relation is fundamental to active galactic nucleus (AGN) studies, enabling supermassive black hole (SMBH) mass estimates and AGN-ba…
A Composite Broad-Line Region in SDSS J1609+4902: a Double-Peaked Disk component and a Gaussian Component
Jiancheng Wu, Qingwen Wu, Chen Hu +6
The profiles of broad emission lines in active galactic nuclei (AGNs) provide critical insights into the geometry and kinematics of the broad-line region (BLR), which in turn influ…
Composite spectrum of Little Red Dot from a standard inner disk and an unstable outer disk
Chenxuan Zhang, Qingwen Wu, Xiao Fan +6
James Webb Space Telescope (JWST) has revealed a new class of high-redshift, very red, compact broad-line sources, termed as "little red dots" (LRDs). The physical mechanism drivin…
Simulation of Binary-Single Interactions in AGN Disk I: Gas-Enhanced Binary Orbital Hardening
Mengye Wang, Yiqiu Ma, Hui Li +4
Stellar-mass binary black hole\,(BBH) mergers within the accretion disks of active galactic nuclei may contribute to gravitational wave\,(GW) events detected by grounded-based GW d…
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…
