Description

I will review some of the main phenomenological signatures of the stochastic acceleration acting in the relativistic jets of blazars. I will link predictions from Monte Carlo simulations and from the numerical solution of the diffusion equation in momentum space, to the spectral features observed in the multi-wavelength SED of blazars. In particular, I will focus on the spectral evolution and spectral curvature in the X-ray and in the TeV data. Finally, I will discuss the formation of pile-up during strong flares.
