Simulations of interaction between outflow and surrounding broken power-law circumnuclear medium: implications for different radio light curves of TDEs
Xiangli Lei, Qingwen Wu, Chang Zhou +4
The complex radio light curves of tidal disruption events (TDEs) challenge our understanding of the properties of both the outflows and the circumnuclear medium (CNM) surrounding s…
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…
Accretion-Mode Transition: The Driver Behind Spectral Changes in Changing-Look AGNs
Pengyuan Han, Huaiyuan Lu, Bing Lyu +2
The physical origin of optical changing-look AGNs (CLAGNs), characterized by the appearance or disappearance of broad emission lines, is thought to be mainly driven by the variatio…
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…
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…
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…
