Quasi-periodic behaviour in the $\gamma$-ray light curve of the blazar PKS 0405-385

Yunlu Gong, Liancheng Zhou, Min Yuan +3

We analyze the quasi-periodic oscillation (QPO) of the historical light curve of FSRQs PKS 0405-385 detected by the Fermi LAT from August 2008 to November 2021. To identify and det…
