Variability Analysis of Fermi-LAT and FACT blazar light curves — •Sarah Wagner, Daniela Dorner, and Karl Mannheim for the FACT collaboration — Julius-Maximilians-Universität Würzburg

Blazars are active galactic nuclei with a relativistic outflow directed closely towards our line of sight showing rapidly variable non-thermal continuum emission. We present a flare analysis of blazar light curves observed with Fermi-LAT and FACT in order to better understand the physical processes that give rise to the observed variability. Based on Bayesian blocks and the HOP algorithm, the asymmetries of flux rise and decay time are studied.
