The Radio/Gamma Connection of Blazars from High to Low Radio Frequencies
Xu-Liang Fan, Qingwen Wu
We construct a large sample of gamma-ray blazars with low-frequency radio data using the recent released TGSS AD1 catalog at 150 MHz. The radio/gamma connections of blazars are com…
Constraints on the composition, magnetization, and radiative efficiency in jet of blazar
Xu-Liang Fan, Qingwen Wu, Neng-Hui Liao
The composition and energy dissipation in jets are two of the fundamental questions of jet physics that are not fully understood. In this paper, we attempt to constrain the composi…
On the intrinsic shape of gamma-ray spectrum for Fermi blazars
Shi-Ju Kang, Qingwen Wu, Yong-Gang Zheng +8
The curvature of the -ray spectrum in blazars may reflect the intrinsic distribution of the emitting electron distribution, which will further give some information on the possi…
Optical and Gamma-Ray Variability Behaviors of 3C 454.3 from 2006 to 2011
Xu-Liang Fan, Shao-Kun Li, Neng-Hui Liao +8
We present our photometric monitoring of a flat spectrum radio quasar (FSRQ) 3C 454.3 at Yunnan observatories from 2006 to 2011. We find that the optical color of 3C 454.3 shows ob…
