Spectroscopic Monitoring of Blazar S5 0716+714: Brightness-Dependent Spectral Behavior
Hai-Cheng Feng, Sen. Yang, Zi-Xu. Yang +17
In this paper, we report the new results of spectroscopic observations of -ray blazar S5 0716+714 from 2019 September to 2020 March with the 2.4 m optical telescope at Lijiang O…
Formation of the Electronic Spectrum in Relativistic Jets of Gamma-Ray Blazars
Y. G. Zheng, G. B. Long, C. Y. Yang +1
We describe the theory of Fermi-type acceleration, including first-order Fermi acceleration at a parallel shock front and second-order Fermi acceleration in a test particle limit.…
Verification of the diffusive shock acceleration in Mrk 501
Y. G. Zheng, G. B. Long, C. Y. Yang +1
The present work considers a plane shock front propagating along a cylindrical jet. Electrons experience the diffusive shock acceleration around the shock front, and subsequently d…
The flat-spectrum radio quasar 3C 345 from the high to the low emission state
M. Berton, N. H. Liao, G. La Mura +17
We report simultaneous observations at different energy bands in radio, optical, UV, X-rays and rays of the flat-spectrum radio-quasar 3C 345. We built the light curve of the s…
Rapid high-amplitude gamma-ray variability in Blazar PKS 0507+17
N. H. Liao, J. M Bai
We report a detailed analysis of -ray data of 2FGL J0509.9+1802 observed by the Large Area Telescope on board {\it Fermi} satellite, especially focusing on April 2013 when extra…
Hints of correlation between broad-line and radio variations for 3C 120
H. T. Liu, J. M. Bai, J. M. Wang +1
In the paper, we investigate correlation between broad-line and radio variations for broad-line radio galaxy 3C 120. By the z-transformed discrete correlation function method and t…
