Periodicity analysis for KAIT plus ZTF blazars

Abstract Using public data from the Katzman Automatic Imaging Telescope (KAIT) and the Zwicky Transient Facility (ZTF), we constructed an R band light curve dataset spanning over 5000 days for 135 blazars, and investigated their quasi-periodic oscillations (QPOs) via the generalized Lomb-Scargle (GLS) and Weighted Wavelet Z-transform (WWZ) methods. With certain empirical criteria, we detected four blazars, including J0507+6737, J0816-1311, J1015+4926 and J1838+4802 with QPOs beyond 3σ significan
