The accretion ratios in Seyfert 2 galaxies with and without hidden broad-line regions
W. Bian, Q. Gu
Using a large sample of 90 Seyfert 2 galaxies (Sy2s) with spectropolarimetric observations, we tested the suggestion that the presence of hidden broad-line regions (HBLRs) in Sy2s…

SDSS J143030.22-001115.1: A misclassified narrow-line Seyfert 1 galaxy with flat X-ray spectrum
Weihao Bian, Quanling Cui, Lihua Chao
We used multi-component profiles to model H and [O III]4959,5007 lines for SDSS J143030.22-001115.1, a narrow-line Seyfert 1 galaxy (NLS1) in a sample of 150 NLS1s candidate…

[O III] emission line in narrow-line Seyfert 1 galaxies
Weihao Bian, Qirong Yuan, Yongheng Zhao
Three sets of two-component profiles are used to simultaneously model the [O III]4959, 5007 and H lines for the Fe II-subtracted spectra of 149 narrow line Seyfert 1 galaxie…
