The Extreme Super-Eddington NLS1 RX J0134.2-4258 -- II. A Weak-Line Seyfert Linking to the Weak-Line Quasar
Chichuan Jin, Chris Done, Martin Ward +3
RX J0134.2-4258 is one of the most super-Eddington narrow-line Seyfert 1 (NLS1) galaxies, on which we conducted a monitoring campaign from radio to X-rays. In this paper, we presen…
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…
Multi-wavelength Campaign on the Super-Eddington NLS1 RX J0134.2-4258 -- I. Peculiar X-ray Spectra and Variability
Chichuan Jin, Chris Done, Martin Ward +3
We have conducted a new long-term multi-wavelength campaign on one of the most super- Eddington narrow-line Seyfert 1s (NLS1s) known, namely RX J0134.2-4258. In this first paper, w…
A Broad Absorption Line Outflow Associated with the Broad Emission Line Region in the Quasar SDSS J075133.35+134548.3
Bo Liu, Hongyan Zhou, Xinwen Shu +4
We report the discovery of unusual broad absorption lines (BALs) in the bright quasar SDSS J075133.35+134548.3 at z~1, and present a detailed study of BAL and emission lines using…
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…
Searching for the Transit of the Earth--mass exoplanet Proxima~Centauri~b in Antarctica: Preliminary Result
Hui-Gen Liu, Peng Jiang, Xingxing Huang +21
Proxima Centauri is known as the closest star from the Sun. Recently, radial velocity observations revealed the existence of an Earth-mass planet around it. With an orbital period…
Photoionization-driven Absorption Lines Variability in Balmer Absorption Line Quasar LBQS 1206+1052
Luming Sun, Hongyan Zhou, Tuo Ji +10
In this paper we present an analysis of absorption line variability in mini-BAL quasar LBQS 1206+1052. The SDSS spectrum demonstrates that the absorption troughs can be divided int…
Strong Optical and UV Intermediate-Width Emission Lines in the Quasar SDSS J232444.80-094600.3: Dust-Free and Intermediate-Density Gas at the Skin of Dusty Torus ?
Zhenzhen Li, Hongyan Zhou, Lei Hao +3
Emission lines from the broad emission line region (BELR) and the narrow emission line region (NELR) of active galactic nuclei (AGNs) are extensively studied. However, between thes…
Detection of the Intermediate-width Emission Line Region in Quasar OI 287 with the Broad Emission Line Region Obscured by the Dusty Torus
Zhenzhen Li, Hongyan Zhou, Lei Hao +8
The existence of intermediate-width emission line regions (IELRs) in active galactic nuclei has been discussed for over two decades. A consensus, however, is yet to be arrived at d…
Strong Variability of Overlapping Iron Broad Absorption Lines in Five Radio-selected Quasars
Shaohua Zhang, Hongyan Zhou, Tinggui Wang +6
We present the variability study of broad absorption lines (BALs) in a uniformly radio-selected sample of 28 BAL quasars using the archival data from the FIRST Bright Quasar Survey…
A Comprehensive Study of Broad Absorption Line Quasars: I. Prevalence of HeI* Absorption Line Multiplets in Low-Ionization Objects
Wen-Juan Liu, Hongyan Zhou, Tuo Ji +13
Neutral Helium multiplets, HeI*3189,3889,10830 are very useful diagnostics to the geometry and physical conditions of the absorbing gas in quasars. So far only a handful of HeI* de…
Coexistence of Gravitationally Bound and Radiation Driven CIV Emission Line Regions in Active Galactic Nuclei
Huiyuan Wang, Tinggui Wang, Hongyan Zhou +4
There are mutually contradictory views in the literature of the kinematics and structure of high-ionization line (e.g. CIV) emitting regions in active galactic nuclei (AGNs). Two k…
