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…
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…
Design of Near Infrared Sky Brightness Monitor and Test Running at Ngari Observatory in Tibet
Qi-Jie Tang, Jian Wang, Shu-cheng Dong +16
Tibet is known as the third pole of the earth, as high as the South Pole and North Pole. The Ngari (Ali) observatory in Tibet has the advantage of plenty of photometric night, low…
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…
