Comparison between Detected and non- Detected Superluminal Sources
Hubing Xiao, Junhui Fan, Jianghe Yang +8
Active galactic nuclei (AGNs) have been attracting research attention due to their special observable properties. Specifically, a majority of AGNs are detected by Fermi-LAT mission…
Optical monitoring of BL Lac object S5 0716+714 and FSRQ 3C273 from 2000 to 2014
Yu-Hai Yuan, Jun-hui Fan, Jun Tao +5
Using the 1.56m telescope at the Shanghai Observatory (ShAO), China, we monitored two sources, BL Lac object S5 0716+714 and Flat Spectrum Radio Quasar (FSRQ) 3C 273. For S5 0716+7…
Optical Monitoring of the Seyfert Galaxy NGC 4151 and Possible Periodicities in the Historical Light Curve
Di-Fu Guo, Shao-Ming Hu, Jun Tao +3
We report B, V, and R band CCD photometry of the Seyfert galaxy NGC 4151 obtained with the 1.0-m telescope at Weihai Observatory of Shandong University and the 1.56-m telescope at…
