Hybrid nature of 0846+51W1: a BL Lac object with a narrow line Seyfert 1 nucleus
Hong-Yan Zhou, Ting-Gui Wang, Xiao-Bo Dong +2
We have found a NLS1 nucleus in the extensively studied eruptive BL Lac, 0846+51W1, out of a large sample of NLS1 compiled from the spectroscopic dataset of SDSS DR1. Its optical s…
Partially obscured quasars in the Sloan Digital Sky Survey Early Data Release
Xiao-Bo Dong, Hong-Yan Zhou, Ting-Gui Wang +3
We have compiled a sample of 21 low redshift (z < 0.3), luminous active galactic nuclei (AGN) with large Balmer decrements (Halpha/Hbeta > 7) using the galaxy and QSO catalogs of t…
Obscured Binary Quasar Cores in SDSS J104807.74+005543.5?
Hongyan Zhou, Tinggui Wang, Xueguang Zhang +2
We report the discovery of a possible close binary system of quasars in SDSS J1048+0055. The [OIII]4959,5007 emission lines are clearly double-peaked, and two discrete radio source…
Empirical modeling of the stellar spectrum of galaxies
Cheng Li, Ting-Gui Wang, Hong-Yan Zhou +2
An empirical method of modeling the stellar spectrum of galaxies is proposed, based on two successive applications of Principal Component Analysis (PCA). PCA is first applied to th…
