The Radio and -ray Variability Analysis of S5 0716+714
H. Z. Li, Y. G. Jiang, T. F. Yi +6
We have studied the variability of \object{S5 0716+714} at radio 15 GHz and -ray band using three different methods. A possible periodicity of and $P_γ…
Multi-band Variability Analysis of Mrk 421
H. Z. Li, Y. G. Jiang, D. F. Guo +2
We have assembled the historical variability data of Mrk 421 at radio 15 GHz, X-ray and gamma-ray bands, spanning about 6.3, 10.3 and 7.5 yr, respective- ly. We analyzed the variab…
GRB Spectra in the complex of synchrotron and Compton processes
Yunguo Jiang, Shao-Ming Hu, Xu Chen +6
Under the steady state condition, the spectrum of electrons is investigated by solving the continuity equation under the complex radiation of both the synchrotron and Compton proce…
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…
Long-term optical and radio variability of BL Lacertae
Y. C. Guo, S. M. Hu, C. Xu +6
Well-sampled optical and radio light curves of BL Lacertae in B, V, R, I bands and 4.8, 8.0, 14.5 GHz from 1968 to 2014 were presented in this paper. A possible yr…
Variability of OI 090.4
Shao Ming Hu, Xu Chen, Di Fu Guo
OI 090.4 was monitored on 21 nights from 2006 to 2012 for studying the variability. Strong variations occurred during the past 6 years. The long-term variability amplitude is consi…
