The Correlation between X-ray and UV Properties of BAL QSOs
LuLu Fan, HuiYuan Wang, Tinggui Wang +4
We compile a large sample of broad absorption lines (BAL) quasars with X-ray observations from the \xmm archive data and Sloan Digital Sky Survey Data Release 5. The sample consist…
XMM observations of BAL Quasars with polar outflows
Junxian Wang, Peng Jiang, Hongyan Zhou +3
We have selected a sample of broad absorption line (BAL) quasars which show significant radio variations, indicating the presence of polar BAL outflows. We obtained snapshot XMM ob…
Broad-line Balmer Decrements in Blue Active Galactic Nuclei
Xiaobo Dong, Tinggui Wang, Jianguo Wang +4
We have investigated the broad-line Balmer decrements (Halpha/Hbeta) for a large, homogeneous sample of Seyfert 1 galaxies and QSOs using spectroscopic data obtained in the Sloan D…
SDSS J160531.84+174826.1: A Dwarf Disk Galaxy With An Intermediate-Mass Black Hole
Xiaobo Dong, Tinggui Wang, Weimin Yuan +7
We report the discovery of a dwarf Seyfert 1 active galactic nucleus (AGN) with a candidate intermediate-mass black hole hosted by the dwarf galaxy SDSS J160531.84+174826.1 at z=0.…
A Comprehensive Study of 2 000 Narrow Line Seyfert 1 Galaxies from the Sloan Digital Sky Survey: I. The Sample
Hongyan Zhou, Tinggui Wang, Weimin Yuan +4
This is the first paper in a series dedicated to the study of the emission-line and continuum properties of narrow line Seyfert 1 galaxies (NLS1s). We carried out a systematic sear…
Ensemble Learning Independent Component Analysis of Normal Galaxy Spectra
Honglin Lu, Hongyan Zhou, Junxian Wang +4
In this paper, we employe a new statistical analysis technique, Ensemble Learning for Independent Component Analysis (EL-ICA), on the synthetic galaxy spectra from a newly released…
