Optical Spectral Variations of a Large Sample of Fermi Blazars
Zhang Bing-Kai, Zhao Xiao-Yun, Wu Qi
We have investigated the optical spectral behavior of a large sample of Fermi blazars (40 FSRQs and 13 BL Lacs), and found two new universal optical spectral behaviors. In the low…
Long-term multi-wavelength variations of Fermi blazar 3C 279
Bing-Kai Zhang, Min Jin, Xiao-Yun Zhao +2
The long-term optical, X-ray and -ray data of blazar 3C 279 have been compiled from -XRT, PCA, -LAT, SMARTS and literature. The source exhibits strong varia…
Long-term optical-infrared color variability of blazars
Bing-Kai Zhang, Xiao-Shan Zhou, Xiao-Yun Zhao +1
The long-term optical and infrared color variability of blazars has been investigated with the SMARTS monitoring data. The sample in this study consists of 49 flat spectrum radio q…
Optical quasi-periodic oscillation and color behavior of blazar PKS 2155-304
Bing-Kai Zhang, Xiao-Yun Zhao, Chun-Xiao Wang +1
PKS 2155-304 is a well studied BL Lac object in the southern sky. The historical optical data during different period have been collected and compiled. Light curves with a time spa…
