Abstract:Context. Monthly-binned γ-ray light curves of 236 bright γ-ray sources, particularly blazars, selected from a sample of 2278 highgalactic latitude objects observed with Fermi-LAT, show flux variability characterised by power spectral densities consisting of a single power-law component, ranging from Brownian to white noise. Aims. The main goal here is to assess the Ornstein-Uhlenbeck (OU) model by studying the range of its three parameters that reproduces these statistical properties. Methods. We develop proce… Show more
