Abstract: This study explores the detection of quasiperiodic oscillations (QPOs) in blazars as a method to identify kink events within their jets, utilizing both γ-ray and polarized light observations. Focusing on a sample of nine blazars, we analyze γ-ray light curves to identify significant QPOs. In addition to γ-ray data, we incorporated polarized light data corresponding to the same temporal segments to cross-validate the presence of QPOs. However, the limited availability of comprehensive polarized data restricted our ability to perform a thorough analysis across all data sets. Despite these limitations, our analysis reveals a segment where QPOs in polarized light coincided with those observed in γ-rays, providing preliminary evidence supporting the kink origin of these oscillations.
