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…
Profile of and Variability in Double-Peaked Balmer Emission Lines in 3C 445
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +2
We extract the multiple-epoch Balmer-line profiles of the heavily obscured quasar 3C 445 from the spectral curves in the literature, and analyze the emission-line profiles of the H…
Fast Inflow Directly Feeding Black Hole Accretion Disk in Quasars
Hongyan Zhou, Xiheng Shi, Weimin Yuan +21
Quasars are high-luminosity active galactic nuclei believed to be powered by accretion of interstellar matter onto a super-massive black hole (SMBH) therein. Most of the observed e…
SDSS J153636.22+044127.0 and its analogues: shocked outflows, not active binary black holes
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +6
The binary emission-line system, particularly the binary broad-line emission system, is considered the most effective indicator of the black hole binary. A plausible example of suc…
A Deeply Buried Narrow-Line Seyfert 1 Nucleus Uncovered in Scattered Light
Xiang Pan, Honglin Lu, S. Komossa +13
We present spectropolarimetric and spectrophotometric observations of the peculiar active galactic nucleus (AGN) SDSS J120300.19+162443.7 (hereafter J1203+1624) at . Its…
