We report the analysis of the gamma-ray variability of NGC 1275–the radio
galaxy at the center of the Perseus cluster. NGC 1275 has been observed
continuously with the Fermi Large Area Telescope over the last nine years. We
applied different time-domain analysis methods including Fourier, wavelets and
Bayesian methods, in order to search for quasi-periodic oscillations in the
gamma-ray emission. We found no evidence for periodicities of astrophysical
origin.
