A Metal-Strong and Dust-Rich Damped \lya Absorption System toward the Quasar SDSS J115705.52+615521.7
Jian-Guo Wang, Hong-Yan Zhou, Jian Ge +7
(Abridged for arXiv) We report the discovery of an unusual, extremely dust-rich and metal-strong damped \lya absorption system (DLA) at a redshift toward the quasar…
Rapid Infrared Variability of Three Radio-loud Narrow-line Seyfert 1 Galaxies: A View from the Wide-field Infrared Survey Explorer
Ning Jiang, Hong-Yan Zhou, Luis C. Ho +6
Using newly released data from the Wide-field Infrared Survey Explorer, we report the discovery of rapid infrared variability in three radio-loud narrow-line Seyfert 1 galaxies (NL…
A Uniformly Selected Sample of Low-mass Black Holes in Seyfert 1 Galaxies
Xiao-Bo Dong, Luis C. Ho, Weimin Yuan +4
We have conducted a systematic search of low-mass black holes (BHs) in active galactic nuclei (AGNs) with broad Halpha emission lines, aiming at building a homogeneous sample that…
Discovery of six high-redshift quasars with the Lijiang 2.4m telescope and the Multiple Mirror Telescope
Xue-Bing Wu, Wen-Wen Zuo, Qian Yang +6
Quasars with redshifts greater than 4 are rare, and can be used to probe the structure and evolution of the early universe. Here we report the discovery of six new quasars with …
Contributions to the cross shock electric field at supercritical perpendicular shocks: Impact of the pickup ions
Zhongwei Yang, Desheng Han, Huigen Yang +4
A particle-in-cell code is used to examine contributions of the pickup ions (PIs) and the solar wind ions (SWs) to the cross shock electric field at the supercritical, perpendicula…
Metallicity and Quasar Outflows
Huiyuan Wang, Hongyan Zhou, Weimin Yuan +1
Correlations are investigated of the outflow strength of quasars, as measured by the blueshift and asymmetry index (BAI) of the CIV line (Wang et al. 2011), with intensities and ra…
Extreme Coronal Line Emitters: Tidal Disruption of Stars by Massive Black Holes in Galactic Nuclei?
Tinggui Wang, Hongyan Zhou, S. Komossa +3
Tidal disruption of stars by supermassive black holes at the centers of galaxies is expected to produce unique emission line signatures, which have not yet been explored adequately…
Correlation Analysis of a Large Sample of Narrow-Line Seyfert 1 Galaxies: Linking Central Engine and Host Properties
Dawei Xu, S. Komossa, Hongyan Zhou +5
We present a statistical study of a large, homogeneously analyzed sample of narrow-line Seyfert 1 (NLS1) galaxies, accompanied by a comparison sample of broad-line Seyfert 1 (BLS1)…
