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…
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…
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…
Quasar 2175 Å dust absorbers II: Correlation analysis and relationship with other absorption line systems
Jingzhe Ma, Jian Ge, J. Xavier Prochaska +6
We present the cold neutral content (H I and C I gas) of 13 quasar 2175 Å dust absorbers (2DAs) at = 1.6 - 2.5 to investigate the correlation between the presence of the UV…
Study on 2015 June 22 Forbush decrease with the muon telescope in Antarctic
De-Hong Huang, Hong-Qiao Hu, Ji-Long Zhang +4
By the end of 2014, a cosmic ray muon telescope was installed at Zhongshan Station in Antarctic and has been continuously collecting data since then. It is the first surface muon t…
