Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. VIII. Structure of the Broad-Line Region and Mass of the Central Black Hole in Mrk 142
Yan-Rong Li, Yu-Yang Songsheng, Jie Qiu +9
This is the eighth in a series of papers reporting on a large reverberation mapping campaign to measure black hole (BH) mass in high accretion rate active galactic nuclei (AGNs). W…
Kinematics of the Broad-line Region of 3C 273 from a Ten-year Reverberation Mapping Campaign
Zhi-Xiang Zhang, Pu Du, Paul S. Smith +9
Despite many decades of study, the kinematics of the broad-line region of 3C~273 are still poorly understood. We report a new, high signal-to-noise, reverberation mapping campaign…
Monitoring AGNs with Hβ Asymmetry. I. First Results: Velocity-resolved Reverberation Mapping
Pu Du, Michael S. Brotherton, Kai Wang +12
We have started a long-term reverberation mapping project using the Wyoming Infrared Observatory 2.3 meter telescope titled "Monitoring AGNs with Hβ Asymmetry" (MAHA). The motivati…
A High-Quality velocity-delay map of the broad-line region in NGC 5548
Ming Xiao, Pu Du, Kai-Xing Lu +10
NGC 5548 has been well spectroscopically monitored for reverberation mapping of the central kinematics by 19 campaigns. Using the maximum entropy method in this Letter, we build up…
Supermassive black holes with high accretion rates in active galactic nuclei. VII. Reconstruction of velocity-delay maps by maximum entropy method
Ming Xiao, Pu Du, Keith D. Horne +11
As one of the series of papers reporting on a large reverberation mapping campaign, we apply the maximum entropy method (MEM) to 9 narrow-line Seyfert 1 galaxies with super-Eddingt…
Galaxy Morphology Classification with Deep Convolutional Neural Networks
Jia-Ming Dai, Jizhou Tong
We propose a variant of residual networks (ResNets) for galaxy morphology classification. The variant, together with other popular convolutional neural networks (CNNs), are applied…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. IX 10 New Observations of Reverberation Mapping and Shortened H Lags
Pu Du, Zhi-Xiang Zhang, Kai Wang +10
As one of the series of papers reporting on a large reverberation mapping campaign of super-Eddington accreting massive black holes (SEAMBHs) in active galactic nuclei (AGNs), we p…
