Optically Thick Outflow Driven by Supercritical Accretion May Explain Little Red Dots

Jun-Rong Liu, Hua Feng, Luis C. Ho

Recent JWST observations have revealed a population of compact, optically red sources known as Little Red Dots (LRDs). A popular interpretation is that LRDs host massive black hole…

Reduced Incidence of Little Red Dots at z < 3 from Number Density and Halo Mass Evolution

Chenxuan Zhang, Huanian Zhang, Qingwen Wu +2

An intriguing puzzle in extragalactic astronomy is the scarcity of Little Red Dots (LRDs) at , compared to their higher abundance at earlier cosmic epochs. To investigate th…

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),…

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…

A Short-lived Rejuvenation during the Decades-long Changing-look Transition in the Nucleus of Mrk 1018

Kai-Xing Lu, Yan-Rong Li, Qingwen Wu +13

Changing-look active galactic nuclei (CL-AGNs), characterized by emerging or disappearing of broad lines accompanied with extreme continuum flux variability, have drawn much attent…
