Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XII. Reverberation Mapping Results for 15 PG Quasars from a Long-Duration High-Cadence Campaign
Chen Hu, Sha-Sha Li, Sen Yang +15
We present the first results from long-term high-cadence spectroscopic monitoring of 15 PG quasars with relatively strong Fe II emission as a part of a broader reverberation mappin…
Monitoring AGNs with H Asymmetry. V. Long-term Variation and Evolution of the Broad H Emission-Line Profiles
Feng-Na Fang, Pu Du, Michael S. Brotherton +40
The physical origins of the diverse emission-line asymmetries observed in the spectra of active galactic nuclei (AGNs) remain incompletely understood. Monitoring the temporal varia…
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 $…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XIII. Ultraviolet Time Lag of H Emission in Mrk 142
V. C. Khatu, S. C. Gallagher, K. Horne +17
We performed a rigorous reverberation-mapping analysis of the broad-line region (BLR) in a highly accreting () active galactic nucleus, Markarian 142 (…
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…
Dust distributions in the Magellanic Clouds
B. -Q. Chen, H. -L. Guo, J. Gao +3
We present high-resolution maps of the dust reddening in the Magellanic Clouds (MCs). The maps cover the Large and Small Magellanic Cloud (LMC and SMC) area and have a spatial angu…
