Active Galactic Nuclei with Ultra-fast Outflows Monitoring Project: The Broad-line Region of Mrk 79 as a Disk Wind
Kai-Xing Lu, Jin-Ming Bai, Zhi-Xiang Zhang +23
We developed a spectroscopic monitoring project to investigate the kinematics of the broad-line region (BLR) in active galactic nuclei (AGN) with ultra-fast outflows (UFOs). Mrk~79…
Untangling Optical Emissions of the Jet and Accretion Disk in the Flat-Spectrum Radio Quasar 3C 273 with Reverberation Mapping Data
Yan-Rong Li, Zhi-Xiang Zhang, Chichuan Jin +4
3C 273 is an intensively monitored flat-spectrum radio quasar with both a beamed jet and blue bump together with broad emission lines. The coexistence of the comparably prominent j…
A parallax distance to 3C 273 through spectroastrometry and reverberation mapping
Jian-Min Wang, Yu-Yang Songsheng, Yan-Rong Li +2
Distance measurements for extragalactic objects are a fundamental problem in astronomy and cosmology. In the era of precision cosmology, we urgently need better measurements of cos…
Supermassive black holes with high accretion rates in active galactic nuclei: X. Optical variability characteristics
Kai-Xing Lu, Ying-Ke Huang, Zhi-Xiang Zhang +10
We compiled a sample of 73 active galactic nuclei (AGNs) with reverberation mapping (RM) observations from RM campaigns including our ongoing campaign of monitoring super-Eddington…
Reverberation mapping of narrow-line Seyfert 1 galaxy I Zwicky 1: black hole mass
Ying-Ke Huang, Chen Hu, Yu-Lin Zhao +11
We report results of the first reverberation mapping campaign of I Zwicky 1 during -, which showed unambiguous reverberations of the broad H line emission to the var…
