Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XV. Reverberation Mapping of Mg II Emission Lines
Hua-Rui Bai, Pu Du, Chen Hu +25
As the 15th paper in a series reporting on a large reverberation mapping (RM) campaign of super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs),…
Little red dots as embryos of active galactic nuclei
Jian-Min Wang, Yi-Lin Wang, Yong-Jie Chen +7
As an unprecedented large population in the early universe, the JWST-discovered little red dots (LRDs) have garnered much attention for formation of massive black holes and galaxie…
Spectroastrometry and Reverberation Mapping of Active Galactic Nuclei. II. Measuring Geometric Distances and Black Hole Masses of Four Nearby Quasars
Yan-Rong Li, Jinyi Shangguan, Jian-Min Wang +35
The geometric distances of active galactic nuclei (AGNs) are challenging to measure because of their exceptionally compact structure yet vast cosmic distances. A combination of spe…
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…
A New Interpretation for the Hot Corona in Active Galactic Nuclei
Yu Zhao, Yan-Rong Li, Jian-Min Wang
This work attempts to provide a new interpretation for the hot corona in active galactic nuclei (AGNs). A thin parabolic magnetic reconnection layer, anchored at the innermost disk…
Bulge Oscillation Driven by Outflows of Active Galactic Nuclei. I. Fast Outflow Case
Yue-Chang Peng, Jian-Min Wang, Yu Zhao +1
There is growing evidence for star formation inside outflows of active galactic nuclei (AGNs). The formed stars are injected into bulges and give rise to perturbation of bulges. In…
