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…
Metal Enriched Outflows and Dusty starburst in the type II quasar Q 1321+058
Ting-Gui Wang, Hongyan Zhou, Honglin Lu +3
We present an analysis of the emission line property and the broad band spectral energy distribution of the ultra-luminous infrared Type II quasar Q132+058. The optical and ultravi…
Broad-line AGNs with Candidate Intermediate-mass Black holes in the Sloan Digital Sky Survey
Xiaobo Dong, Tinggui Wang, Weimin Yuan +5
We have conducted a systematic search of AGNs with IMBHs from the SDSS DR4. As results we found 245 candidates of broad-line AGN with M_{BH}<10^6 \Msun estimated from the luminosit…
Systematic study of a large sample of NLS1 galaxies from SDSS: first results
Weimin Yuan, Hongyan Zhou, Tinggui Wang +6
This proceedings contribution summarizes first results obtained from a systematic study of 2011 NLS1 galaxies, as presented in Zhou et al. (2006, ApJS 166, 128). The sample was com…
Calculation of the quark condensate through Schwinger-Dyson equation
Z. G. Wang, S. L. Wan
In this letter, we clarify the algebra expression for calculating the quark condensate based on the non-perturbative quark propagator calculated through Schwinger-Dyson equation. T…
