The environmental dependence of X-ray AGN activity at
E. Noordeh, R. E. A. Canning, A. King +9
We present an analysis of the X-ray Active Galactic Nucleus (AGN) population in a sample of seven massive galaxy clusters in the redshift range . We utilize high-quali…
The frequency of extreme X-ray variability of radio-quiet quasars
John D. Timlin, W. Niel Brandt, Shifu Zhu +3
We analyze 1598 serendipitous Chandra X-ray observations of 462 radio-quiet quasars to constrain the frequency of extreme amplitude X-ray variability that is intrinsic to the quasa…
Piercing through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields. II. Are Highly Obscured AGNs the Missing Link in the Merger-Triggered AGN-Galaxy Coevolution Models?
Junyao Li, Yongquan Xue, Mouyuan Sun +12
By using a large highly obscured () AGN sample (294 sources at ) selected from detailed X-ray spectral analyses in the deepest Chandra…
On the Fraction of X-ray Weak Quasars from the Sloan Digital Sky Survey
Xingting Pu, B. Luo, W. N. Brandt +4
We investigate systematically the X-ray emission from type 1 quasars using a sample of 1825 Sloan Digital Sky Survey (SDSS) non-broad absorption line (non-BAL) quasars with Chandra…
Revealing the relation between black-hole growth and host-galaxy compactness among star-forming galaxies
Q. Ni, W. N. Brandt, G. Yang +8
Recent studies show that a universal relation between black-hole (BH) growth and stellar mass () or star formation rate (SFR) is an oversimplification of BH-galaxy co-e…
The -- relation and corona-disk-jet connection in optically selected radio-loud quasars
S. F. Zhu, W. N. Brandt, B. Luo +3
Radio-loud quasars (RLQs) are more X-ray luminous than predicted by the X-ray-optical/UV relation (i.e. ) for radio-quiet quasars (RQQs). The e…
