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…
Local Active Galactic Nuclei with Large Broad-Hα Variability Reside in Red Galaxies
Wen-Juan Liu, Paulina Lira, Su Yao +4
Inspired by our serendipitous discovery of six AGNs with varying broad-Halpha fluxes over years out of our searching for intermediate-mass black holes (IMBHs), we conduct a systema…
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…
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…
