Variability survey in NGC 6910, the open cluster rich in Cephei-type stars
D. Moździerski, A. Pigulski, Z. Kołaczkowski +14
NGC 6910 is the northern hemisphere open cluster known to be rich in Cephei-type stars. Using four-season photometry obtained in Białków (Poland) and Xinglong (China) observato…
The underlying driver for the \civ Baldwin effect in QSOs with
Xue Ge, Wei-Hao Bian, Xiao-Lei Jiang +2
Broad emission lines is a prominent property of type I quasi-stellar objects (QSOs). The origin of the Baldwin effect for \civ Å broad emission lines, i.e., the lumin…
The inner 40 pc Radial Distribution of the Star formation Rate for a nearby Seyfert 2 galaxy M51
Li-Ling Fang, Xiao-Lei Jiang, Zhi-Cheng He +1
We investigate spatially resolved specific star formation rate (SSFR) in the inner 40 pc for a nearby Seyfert 2 galaxy, M51 (NGC 5194) by analyzing spectra obtained with the…
Variability of broad absorption lines in a QSO SDSS J022844.09+000217.0 on multi-year timescales
Zhi-Cheng He, Wei-Hao Bian, Xiao-Lei Jiang +1
The variability of the broad absorption lines is investigated for a broad absorption line (BAL) QSO, SDSS J022844.09+000217.0 (z = 2.719), with 18 SDSS/BOSS spectra covering 4128 d…
Variability of QSOs with variable regions in broad absorption troughs from the Sloan Digital Sky Survey
Zhi-Cheng He, Wei-Hao Bian, Xiao-Lei Jiang +1
The variability of broad absorption lines is investigated for a sample of 188 broad-absorption-line (BAL) quasars (QSOs) () with at least two-epoch observations from the S…
