Distributions of the ratio between the total energy of all relativistic electrons we evolved in our runs at four different epochs, and the thermal gas energy associated with the same tracers. The solid lines give the distribution of E_cr/E_g for the electron evolution model including shocks and turbulent re-acceleration, while the dashed lines are for the electron model only including radiative losses and adiabatic changes after the injection by jets. This figure only includes P/(m_ec)≥10³ electrons in the computation of E_cr.
