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…
CIV wind properties of the SDSS-V X-ray selected quasars: strong optical-to-UV emission is key regardless of X-ray strength
Amy L. Rankine, David Homan, James Aird +25
We present an investigation of the rest-frame optical/UV and X-ray properties for a sample of 3027 X-ray selected quasars between detected in the deepest Spec…
The Drivers of the Decline in Supermassive Black Hole Growth at
Zhibo Yu, W. N. Brandt, Fan Zou +4
It is well established that cosmic supermassive black hole (SMBH) growth peaks at , followed by a strong decline of toward the present day, w…
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…
Investigating the Star-Formation Characteristics of Radio Active Galactic Nuclei
Bojun Zhang, Fan Zou, W. N. Brandt +5
The coevolution of supermassive black holes and their host galaxies represents a fundamental question in astrophysics. One approach to investigating this question involves comparin…
