On the X-ray Baldwin Effect in Active Galactic Nuclei Observed by the Chandra High Energy Grating
Xinwen Shu, Junxian Wang, Tahir Yaqoob +2
Using Chandra High Energy Grating (HEG) observations of 32 AGNs, we present a systematic study of the X-ray Baldwin effect (XBE, i.e. the anti-correlation between narrow Fe Kα line…
On the fraction of X-ray obscured quasars
Junxian Wang, Peng Jiang, Zhenya Zheng +2
Various studies have claimed that the fraction of obscured AGN drops with luminosity, but contrary results are also reported. We present our recent studies on the fraction of X-ray…
On the fraction of X-ray obscured quasars in the local universe
J. X. Wang, P. Jiang
Recent wide area hard X-ray and soft Gamma ray surveys have shown that the fraction of X-ray obscured AGNs in the local universe significantly decreases with intrinsic luminosity.…
On the X-ray Baldwin effect for narrow Fe Kalpha emission line
P. Jiang, J. X. Wang, T. G. Wang
Most Active Galactic Nuclei (AGN) exhibit a narrow Fe Kalpha line at ~ 6.4 keV in the X-ray spectra, due to the fluorescent emission from cold material far from the inner accretion…
Investigating on the nuclear obscuration in two types of Seyfert 2 galaxies
X. W. Shu, J. X. Wang, P. Jiang +2
We build a large sample of Seyfert 2 galaxies (Sy2s) with both optical spectropolarimetric and X-ray data available, in which 29 Sy2s with the detection of polarized broad emission…
