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…
Testing the Tremaine-Weinberg Method Applied to Integral-field Spectroscopic Data Using a Simulated Barred Galaxy
Yanfei Zou, Juntai Shen, Martin Bureau +1
Tremaine and Weinberg (TW) proposed a conceptually simple procedure relying on long-slit spectroscopy to measure the pattern speeds of bars () in disk galaxies. Using a…
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…
A comprehensive and uniform sample of broad-line active galactic nuclei from the SDSS DR7
He-Yang Liu, Wen-Juan Liu, Xiao-Bo Dong +4
A new, complete sample of 14,584 broad-line AGNs at is presented, which are uncovered homogeneously from the complete database of galaxies and quasars observed spectroscop…
SDSS J094635.06+101706.1: a redshift one, very radio-loud, γ-ray emitting narrow-line Seyfert 1 galaxy
Su Yao, S. Komossa, Wen-Juan Liu +4
As hybrids of narrow-line Seyfert 1 (NLS1) galaxies and blazars, γ-ray emitting NLS1s are important probes of jet physics in the high Eddington-ratio regime. Only very few of them…
Initial results from a systematic search for changing-look active galactic nuclei selected via mid-infrared variability
Zhenfeng Sheng, Tinggui Wang, Ning Jiang +6
Changing look active-galatic-nuclei (CL AGNs) can yield considerable insight into accretion physics as well as the co-evolution of black holes and their host galaxies. A large samp…
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…
Rapid "Turn-on" of type 1 AGN in a quiescent early type galaxy SDSS1115+0544
Lin Yan, Tinggui Wang, Jiang Ning +8
We present a detailed study of a transient in the center of SDSS1115+0544 based on the extensive UV, optical, mid-IR light curves (LC) and spectra over 1200 days. The host galaxy i…
