Abstract: The Fokker-Planck equation is a kinetic equation which models the dynamics of a particle distribution function. This equation is applied to describe non-thermal particles in astrophysical scenarios. With Paramo (PArticle and RAdiation MOnitor), the kinetic equation is solved numerically with the proper modeling of the acceleration processes, and accounts for accurate cooling coefficient (e.g., radiative cooling with Klein-Nishina corrections). The numerical solution at every time step is used to calculate radiations processes, namely synchrotron and IC, with sophisticated numerical techniques, obtaining the multi-wavelength spectral evolution of the system.
