The Curious Case of PHL 1811: Heavy Obscuration Versus Intrinsic X-ray Weakness
B. Luo, Xiaolei Chen, Jian Huang +2
We present a systematic X-ray analysis of the narrow-line Type 1 quasar PHL 1811, which has long been regarded as the prototype of intrinsically X-ray weak quasars. A critical brea…
Strong X-ray Variability of I Zwicky 1: Obscuration from Clumpy Accretion-Disk Winds
Jian Huang, Bin Luo, W. N. Brandt +2
Obscuration from clumpy accretion-disk winds has been invoked to explain the extreme X-ray weakness and X-ray variability observed in a substantial fraction of super-Eddington accr…
On the Extremely X-ray Variable Active Galactic Nuclei in the XMM-LSS Field
Zijian Zhang, Bin Luo, Linhua Jiang +3
We present a systematic investigation of extremely X-ray variable active galactic nuclei (AGNs) in the XMM-SERVS XMM-LSS region. Eight variable AGNs are i…
Photometric Selection of type 1 Quasars in the XMM-LSS Field with Machine Learning and the Disk-Corona Connection
Jian Huang, Bin Luo, W. N. Brandt +4
We present photometric selection of type 1 quasars in the XMM-Large Scale Structure (XMM-LSS) survey field with machine learning. We constructed our trai…
The Remarkable X-ray Spectra and Variability of the Ultraluminous Weak-Line Quasar SDSS J1521+5202
Shouyi Wang, W. Niel Brandt, Bin Luo +4
We present a focused X-ray and multiwavelength study of the ultraluminous weak-line quasar (WLQ) SDSS J1521+5202, one of the few X-ray weak WLQs that is amenable to basic X-ray spe…
