Discovery of a Damped Ly Absorber in the Circumnuclear Zone of the FeLoBAL Quasar SDSS J083942.11+380526.3
Shengmiao Wu, Xiheng Shi, Nibedita Kalita +8
SDSS J083942.11+380526.3 () is a FeLoBAL quasar that exhibits visible Balmer absorption lines (H), implying a significant population. The quasar also shows an arr…
On the Origin of the Strong Optical Variability of Emission-line Galaxies
Ruqiu Lin, Zhen-Ya Zheng, Weida Hu +9
Emission-line galaxies (ELGs) are crucial in understanding the formation and evolution of galaxies, while little is known about their variability. Here we report the study on the o…
Broad Emission and Absorption Line Outflows in the Quasar SDSS J163345.22+512748.4
Bo Liu, Hongyan Zhou, Xinwen Shu +4
We present a detailed study of the optical and NIR emission and absorption line spectrum of the quasar SDSS J163345.22+512748.4. We discovered on the newly acquired NIR spectrum a…
Mrk 1239: a Type-2 Counterpart of Narrow-line Seyfert-1?
Xiang Pan, Hongyan Zhou, Chenwei Yang +10
We present new spectrophotometric and spectropolarimetric observations of Mrk 1239, one of the 8 prototypes that defines type-1 narrow-line Seyfert galaxies (NLS1s). Unlike the oth…
A Mid-infrared Flare in the Active Galaxy MCG-02-04-026: Dust Echo of a Nuclear Transient Event
Luming Sun, Ning Jiang, Tinggui Wang +8
We report the discovery of a mid-infrared (MIR) flare using WISE data in the center of the nearby Seyfert 1.9 galaxy MCG-02-04-026. The MIR flare began in the first half of 2014, p…
Discovery of Metastable He I* 10830 Mini-broad Absorption Lines and Very Narrow Paschen Emission Lines in the ULIRG Quasar IRAS F11119+3257
Xiang Pan, Hongyan Zhou, Wenjuan Liu +7
IRAS F11119+3257 is a quasar-dominated Ultra-Luminous InfraRed Galaxy, with a partially obscured narrow-line seyfert 1 nucleus. In this paper, we present the NIR spectroscopy of F1…
