Deep X-ray View of a Distant Protocluster Anchored by a Quasar at : No Evidence for Enhanced X-ray AGN Activity
Shouyi Wang, Feige Wang, Jinyi Yang +22
Whether dense environments accelerate SMBH growth during cosmic reionization remains uncertain because X-ray constraints on protoclusters are rare. We analyze ks of…
A Decade-Scale Ionization Echo of Black-Hole Accretion in Galactic Nuclei
Wei-Jian Guo, Shuo Zhai, Chen Hu +16
Circumnuclear structures in active galactic nuclei respond to accretion variability over different spatial and temporal scales, but whether compact narrow-line gas responds on deca…
Chandra Lensing-cluster Ultradeep Extragalactic Survey (CLUES) I: A 2 Ms Point-Source Catalog of the Abell 2744 Field
Shouyi Wang, Fan Zou, Elena Gallo +10
In the first paper of the Chandra Lensing-cluster Ultradeep Extragalactic Survey (CLUES), we present an ultradeep 2 Ms X-ray survey of the Abell 2744 field constructed from 101 arc…
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…
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…
Intervening nuclear obscuration changing the X-ray look of the QSO CFHQS J164121+375520
Fabio Vito, William Nielsen Brandt, Andrea Comastri +16
X-ray observations of the optically selected QSO CFHQS J164121+375520 (hereafter J1641) revealed that its flux dropped by a factor from 2018, when it was a bri…
