A Quasi-periodic Oscillation in the gamma-ray Emission from the Non-blazar Active Galactic Nucleus PKS 0521-36
Haiyun Zhang, Dahai Yan, Pengfei Zhang +2
Long-term gamma-ray variability of a non-blazar Active Galactic Nucleus (AGN) PKS 0521-36 is investigated by using Fermi-LAT pass 8 data covering from 2008 August to 2021 March. Th…
Gaussian Process Modeling -LAT -ray Blazar Variability: A Sample of Blazars with -ray Quasi-periodicities
Shenbang Yang, Dahai Yan, Pengfei Zhang +2
Blazar variability may be driven by stochastic processes. On the other hand, quasi-periodic oscillation (QPO) behaviors are recently reported to be detected in -LAT dat…
Statistical analysis on X-ray flares from the nucleus and HST-1 knot in the M87 jet
Shenbang Yang, Dahai Yan, Benzhong Dai +4
The statistical properties of X-ray flares from two separate locations (nucleus and HST-1) in the M87 jet are investigated to reveal the physical origin of the flares. We analyse t…
Statistical analysis on XMM-Newton X-ray flares of Mrk 421: distributions of peak flux and flaring time duration
Dahai Yan, Shenbang Yang, Pengfei Zhang +3
The energy dissipation mechanism in blazar jet is unknown. Blazar's flares could provide insights on this problem. Here we report statistical results of XMM-Newton X-ray flares of…
