The changing-look AGN SDSS J101152.98+544206.4 is returning to a type I state
Bing Lyu, Xue-Bing Wu, Yuxuan Pang +11
Aims. We reported the discovery that a changing-look AGN SDSS J101152.98+544206.4 (J1011+5442 for short) gradually returns to the type 1 state after a short period between 2014 and…
Reverberation Mapping of Two Variable Active Galactic Nuclei: Probing the Distinct Characteristics of the Inner and Outer Broad-line Regions
Hai-Cheng Feng, Sha-Sha Li, J. M. Bai +8
Current reverberation mapping (RM) studies primarily focus on single emission lines, particularly the \hb\ line, which may not fully reveal the geometry and kinematic properties of…
Velocity-Resolved Ionization Mapping of Broad Line Region. I. Insights into Diverse Geometry and Kinematics
Sha-Sha Li, Hai-Cheng Feng, H. T. Liu +6
Broad emission lines of active galactic nuclei (AGNs) originate from the broad-line region (BLR), consisting of dense gas clouds in orbit around an accreting supermassive black hol…
Finding Quasars behind the Galactic Plane. II. Spectroscopic Identifications of 204 Quasars at
Yuming Fu, Xue-Bing Wu, Linhua Jiang +21
Quasars behind the Galactic plane (GPQs) are important astrometric references and valuable probes of Galactic gas, yet the search for GPQs is difficult due to severe extinction and…
