Warped accretion disks and quasars with episodic periodicity of long-term variations
Yue-Chang Peng, Jian-Min Wang, Pu Du +2
It has been found that some quasars are undergoing quasi-periodic variations (most of them with damped amplitudes) in optical bands from long-term monitoring campaigns, but how to…
Broad-line Region of the Quasar PG 2130+099. II. Doubling the Size Over Four Years?
Zhu-Heng Yao, Sen Yang, Wei-Jian Guo +16
Over the past three decades, multiple reverberation mapping (RM) campaigns conducted for the quasar PG 2130+099 have exhibited inconsistent findings with time delays ranging from $…
Spectroastrometry and Reverberation Mapping (SARM) of Active Galactic Nuclei. I. The H Broad-line Region Structure and Black Hole Mass of Five Quasars
Yan-Rong Li, Chen Hu, Zhu-Heng Yao +18
We conduct a reverberation mapping (RM) campaign to spectroscopically monitor a sample of selected bright active galactic nuclei with large anticipated broad-line region (BLR) size…
Dependence of Virial Factors on Optical Spectral Properties of Active Galactic Nuclei
Sen Yang, Pu Du, Jian-Min Wang
Reverberation mapping (RM) has long been a powerful tool for measuring the masses of supermassive black holes (SMBHs) at the centers of active galactic nuclei (AGNs), but the preci…
Monitoring AGNs with H Asymmetry. IV. First Reverberation Mapping Results of 14 AGNs
T. E. Zastrocky, Michael S. Brotherton, Pu Du +41
We report first-time reverberation mapping results for 14 AGNs from the ongoing Monitoring AGNs with H Asymmetry campaign (MAHA). These results utilize optical spectra obtained…
X-ray properties of reverberation-mapped AGNs with super-Eddington accreting massive black holes
Jaya Maithil, Michael S. Brotherton, Ohad Shemmer +7
The X-ray properties of Active Galactic Nuclei (AGNs) depend on their underlying physical parameters, particularly the accretion rate. We identified eight reverberation-mapped AGNs…
