A $γ$ -ray Quasi-Periodic modulation in the Blazar PKS 0301 $-$ 243?

Peng-Fei Zhang, Da-Hai Yan, Jia-Neng Zhou +3

We report a nominally high-confidence $γ$ -ray quasi-periodic modulation in the blazar PKS 0301 $-$ 243. For this target, we analyze its \emph{Fermi}-LAT Pass 8 data covering from 200…

Two transient X-ray Quasi-Periodic Oscillations separated by an intermediate state in 1H 0707-495

Peng-Fei Zhang, Peng Zhang, Neng-Hui Liao +3

In the narrow-line Seyfert 1 galaxy 1H 0707-495, recently a transient quasi-periodic oscillation (QPO) signal with a frequency of $\sim 2.6 \times 1 0^{- 4}$ Hz has been detected at a…

Possible Quasi-Periodic modulation in the z = 1.1 $γ$ -ray blazar PKS 0426-380

Pengfei Zhang, Dahai Yan, Nenghui Liao +3

We search for $γ$ -ray and optical periodic modulations in a distant flat spectrum radio quasar (FSRQ) PKS 0426-380 (the redshift $z = 1.1$ ). Using two techniques (i.e., the maximum l…
