X-Ray Properties of Narrow-Line Seyfert 1 Galaxies with Very Small Broad-Line Widths
Y. L. Ai, W. Yuan, H. Y. Zhou +2
Narrow-line Seyfert\,1 galaxies (NLS1s) with very small broad-line widths (say, FWHM(\hb) $\la $ 1200\,\kms) represent the extreme type of Seyfert\,1 galaxies that have small black…

Dependence of the optical/UV variability on the emission line properties and Eddington ratio in active galactic nuclei
Y. L. Ai, W. Yuan, H. Y. Zhou +4
The dependence of the long-term optical/UV variability on the spectral and the fundamental physical parameters for radio-quiet active galactic nuclei (AGNs) is investigated. The mu…
