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…
Bayesian synthesis of astrometric wobble and total light curves in close binary supermassive black holes
Andjelka B. Kovacevic, Yu-Yang Songsheng, Jian-Min Wang +1
We test the potential of Bayesian synthesis of upcoming multi-instrument data to extract orbital parameters and individual light curves of close binary supermassive black holes (CB…
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…
Revisiting Emission-Line Measurement Methods for Narrow-Line Active Galactic Nuclei
Viraja C. Khatu, Sarah C. Gallagher, Keith Horne +16
Measuring broad emission-line widths in active galactic nuclei (AGN) is not straightforward owing to the complex nature of flux variability in these systems. Line-width measurement…
Differential Interferometric Signatures of Close Binaries of Supermassive Black Holes in Active Galactic Nuclei: II. Merged Broad Line Regions
Yu-Yang Songsheng, Jian-Min Wang
Pairs of supermassive black holes (SMBHs) at different stages are natural results of galaxy mergers in the hierarchical framework of galaxy formation and evolution. However, identi…
Spiral Arms in Broad-line Regions of Active Galactic Nuclei. I. Reverberation and Differential Interferometric Signals of Tightly Wound Cases
J. -M. Wang, P. Du, Y. -Y. Songsheng +1
As a major feature in spectra of active galactic nuclei, broad emission lines deliver information of kinematics and spatial distributions of ionized gas surrounding the central sup…
