Identifying Compton-thick active galactic nuclei in the COSMOS. II. Searching among mid-infrared selected AGNs
Xiaotong Guo, Qiusheng Gu, Guanwen Fang +7
Compton-thick active galactic nuclei (CT-AGNs), defined by column density , are so heavily absorbed that their X-ray e…
The mid-infrared variability of the SDSS optical quasars
Hongtao Wang, Yong Shi
Based on the Seventh Data Release (DR7) quasar catalog from the Sloan Digital Sky Survey, we investigate the variability of optical quasars in W1, W2, W3 and W4 bands of the Wide-f…
The comparison of optical variability of broad-line Seyfert 1 and narrow-line Seyfert 1 galaxies from the view of Pan-STARRS
Hongtao Wang, Chao Guo, Hongmin Cao +3
By means of the data sets of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), we investigate the relationship between the variability amplitude and luminosity…
A Hamiltonian Approach to Floating Barrier Option Pricing
Qi Chen, Hong-tao Wang, Chao Guo
Hamiltonian approach in quantum mechanics provides a new thinking for barrier option pricing. For proportional floating barrier step options, the option price changing process is s…
The Variability of the Narrow-line Seyfert 1 Galaxies from the PanSTARRS's View
Hongtao Wang, Yanping Su, Xue Ge +2
By means of the data sets from the Pan-STARRAS1 survey, we have systematically examined the relationship between the variability characteristics and the physical parameters of the…
From the Fermi blazar sequence to the relation between Fermi blazars and gamma-ray Narrow-line Seyfert 1 Galaxies
Yongyun Chen, Qiusheng Gu, Junhui Fan +6
We use the third catalog of blazars detected by Fermi/LAT (3LAC) and gamma-ray Narrow-line Seyfert 1 Galaxies (gamma-NLSy1s) to study the blazar sequence and relationship between t…
