A 34.5 day quasi-periodic oscillation in gamma-ray emission from the blazar PKS 2247-131
Jianeng Zhou, Zhongxiang Wang, Liang Chen +5
Since 2016 October, the active galaxy PKS 2247-131 has undergone a gamma-ray outburst, which we studied using data obtained with the Fermi Gamma-ray Space Telescope. The emission a…
Impact of Plasma Instability on Constraint of the Intergalactic Magnetic Field
Dahai Yan, Jianeng Zhou, Pengfei Zhang +2
A relativistic electron-positron pair beam can be produced in the interaction of TeV photons from a blazar with the extragalactic background light (EBL). The relativistic …
A gamma-ray periodic modulation in Globular Cluster 47 Tucanae
Peng-Fei Zhang, Jia-Neng Zhou, Da-Hai Yan +4
The Globular Cluster 47 Tucanae was firstly detected in gamma-rays by the Large Area Telescope (LAT) onboard the \emph{Fermi} Gamma-ray Space Telescope, and the gamma-ray emission…
Testing relativistic boost as the cause of gamma-ray quasi-periodic oscillation in a blazar
Dahai Yan, Jianeng Zhou, Pengfei Zhang +2
The mechanism for producing gamma-ray quasi-periodic oscillation (QPO) in blazar is unknown. One possibility is the geometric model, in which without the need for intrinsic quasi-p…
