Periodicities and the power spectral density for the accretion rate in the isotropic Run II. Left: Lomb–Scargle periodogram (power vs. period in years) with the most prominent peak at ∼112 years. Other prominent peaks are at ∼204 and ∼54 years. Right: PSD with the best-fit power-law function with the slope of −0.57 ± 0.12.
