The Impact of Elliptical Broad-Line Regions on Reverberation-Based Black Hole Mass Estimates
Jiancheng Wu, Haicheng Feng, Qingwen Wu +1
The virial factor is critical for accurate supermassive black hole (SMBH) mass measurements using reverberation mapping (RM) and the radius--luminosity (--) relation, yet…
Formation of dust clumps in the torus of active galactic nuclei
Xinwu Cao, Renyue Cen, Qingwen Wu +1
The putative dusty torus is a key ingredient of the unification scheme of active galactic nuclei (AGN), but its origin remains a mystery. Here we put forward a new physical model t…
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…
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…
