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…
Discovery of An Active Intermediate-Mass Black Hole Candidate in the Barred Bulgeless Galaxy NGC 3319
Ning Jiang, Tinggui Wang, Hongyan Zhou +7
We report the discovery of an active intermediate-mass black hole (IMBH) candidate in the center of nearby barred bulgeless galaxy . The point X-ray source revealed b…
A Strange EUV Emission: Scattered Continuum in the Lymann Limit Absorption Edge toward the Quasar SDSS J125903.26+621211.5?
Xiang Pan, Shaohua Zhang, Hongyan Zhou +5
We identified a peculiar proximate sub-damped Lya absorption system (sub-DLA) at z=3.234 with a neutral hydrogen column density of toward the…
Ultra-dense Broad-line Region Scale Outflow in Highly Reddened Quasar SDSS J145057.28+530007.6
Shaohua Zhang, Hongyan Zhou, Xiheng Shi +3
We report the discovery of highly reddening and hydrogen Balmer and metastable helium broad absorption lines in the quasar SDSS J145057.28+530007.6, based on the optical and near-i…
An Intercomparison Study of Two Proximate Damped Ly Systems with Residual Flux upon the Ly Absorption Trough toward Quasars
Xiaoyi Xie, Hongyan Zhou, Xiang Pan +6
In this paper, we present an intercomparison study of two quasars, SDSS J145618.32+340037.2 and SDSS J215331.50-025514.1, which have proximate damped Lya systems (PDLAs) with resid…
A Uniformly Selected Sample of Low-Mass Black Holes in Seyfert 1 Galaxies. II. The SDSS DR7 Sample
He-Yang Liu, Weimin Yuan, Xiao-Bo Dong +2
A new sample of 204 low-mass black holes (LMBHs) in active galactic nuclei (AGNs) is presented with black hole masses in the range of (1-20) * 10^5 M_sun. The AGNs are selected fro…
