Active Galactic Nuclei (AGN) have been discovered more than 50 years ago and yet they remain mysterious. Although we are sure they are powered by a supermassive black hole fed by an accretion disk and that they sometimes display a relativistic jet, the links between the black hole, the disk and the jet along with the acceleration and emission mechanisms are still unclear. Leptonic and hadronic models managing both in explaining the spectral energy distribution (SED) of blazars at high energy (in the GeV-TeV range), there is a degeneracy. However, blazars are known to be highly variable in all wavelengths. This variability can trace the mechanisms at play in the central engine and in the jet, giving a tool to discriminated between different ...
