Testing [O II] as a Star Formation Rate Tracer in Quasar Host Galaxies
Xiaotong Feng, Xue-Bing Wu, Yuming Fu +3
The [O II] emission line is a widely used star formation rate (SFR) tracer. However, its application to type I quasars is not straightforward, because the line can be…
Far-Infrared Star Formation Rates of Quasar Host Galaxies from Multiwavelength Spectral Energy Distribution Decomposition
Xiaotong Feng, Xue-Bing Wu, Yuming Fu +3
Reliable star formation rates (SFRs) are essential for studying the connection between black hole growth and quasar host galaxies. We study the far-infrared (FIR) SFRs and the host…
Radio-detected Lya emitters at 1.88 < z < 3.52: AGN fraction and Lya emission
Sai Zhai, Huub Röttgering, Anniek J. Gloudemans +10
Lya emitters (LAEs) are galaxies with strong Lya emission, tracing early star formation and ionizing radiation. Their connection to active galactic nuclei (AGNs) is key to understa…
X-ray variability of SDSS J000532.84+200717.4: from a normal state to an X-weak state
Xiaohui Yang, Yanli Ai, Liming Dou +8
We present a multi-epoch study of the extreme X-ray variability of the type~1 quasar SDSS~J000532.84+200717.4 using archival observations from \textit{XMM-Newton}, \textit{Swift}/X…
A Rare Eddington-Limited, Heavily Obscured Low-Mass Active Galactic Nucleus Likely Triggered by a Galaxy Merger
Shouyi Wang, Fan Zou, Chang-Hao Chen +7
We report a detailed analysis of GAMA 376183, a powerful, heavily obscured active galactic nucleus (AGN) hosted by a low-mass galaxy () likely ex…
The Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST) Quasar Survey: Quasar Properties from Data Release 10 to 12
Bing Lyu, Xue-Bing Wu, Jun-Jie Jin +9
We present the quasar catalog from Data Releases 10 to 12 of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Quasar Survey, comprising quasars observed betwe…
