Description
Most research in blazar variability focuses on individual flares to explain acceleration
and radiation mechanisms and improve on current models. These short-time events (minutes,
hours or days) might not be representative of the underlying mechanisms causing small-
amplitude variability and/or continuous emission present most of the time. We therefore
investigate long-term (month to years) variability of blazar emission in the framework
of current leptonic blazar models. For this purpose, we introduce generated time-
dependent parameter variations which are based on typical Power Spectral Densities (PSDs)
associated with the variability of accreation flows. The PSDs from the resulting
light curves are analyzed and compared to one another as well as the PSD of the variation
PSD. Correlations between light curves are also investigated to aid identification of
charactersitic variation patterns associated with leptonic models.
