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),…

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…

The Host Galaxy of the Hyperactive Repeating FRB 20240114A: Behind a Galaxy Cluster

Xiang-Lei Chen, Chao-Wei Tsai, Di Li +16

We report on the optical spectroscopic observations of the host galaxy of the hyperactive repeating fast radio burst, FRB 20240114A. The host galaxy is a dwarf galaxy at a redshift…

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 $…

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…
