Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XIV. Long-Duration High-Cadence Reverberation Mapping Results for 11 PG Quasars
Chen Hu, Zhu-Heng Yao, Yong-Jie Chen +20
We report the results of a long-duration high-cadence reverberation mapping campaign of a second batch of 11 PG quasars using the 2.2m telescope at the Calar Alto Observatory. This…
Testing Super-Eddington Accretion onto a Supermassive Black Hole: Reverberation Mapping of PG 1119+120
Fergus R. Donnan, Juan V. Hernández Santisteban, Keith Horne +11
We measure the black hole mass and investigate the accretion flow around the local () quasar PG 1119+120. Spectroscopic monitoring with Calar Alto provides H lags and…
OccDepth: A Depth-Aware Method for 3D Semantic Scene Completion
Ruihang Miao, Weizhou Liu, Mingrui Chen +4
3D Semantic Scene Completion (SSC) can provide dense geometric and semantic scene representations, which can be applied in the field of autonomous driving and robotic systems. It i…
Ultrafast Inorganic Crystals with Mass Production Capability for Future High-Rate Experiments
Chen Hu, Liyuan Zhang, Ren-Yuan Zhu
Future HEP experiments present stringent challenges to inorganic scintillators in both fast timing response and radiation tolerance. This paper reports recent progress in developin…
Outflows from active galactic nuclei: The BLR-NLR metallicity correlation
Pu Du, Jian-Min Wang, Chen Hu +4
The metallicity of active galactic nuclei (AGNs), which can be measured by emission line ratios in their broad and narrow line regions (BLRs and NLRs), provides invaluable informat…
A Systematic Analysis of Fe II Emission in Quasars: Evidence for Inflow to the Central Black Hole
Chen Hu, Jian-Min Wang, Luis C. Ho +4
Broad Fe II emission is a prominent feature of the optical and ultraviolet spectra of quasars. We report on a systematical investigation of optical Fe II emission in a large sample…
