Time evolution of feedback energy and mass depletion inside R_500, c. Top: the dotted line represents the time-integrated ratio between feedback energy and the thermal energy of the system (“dE/E”), and the solid line shows the mass depletion computed as the difference between the baryon fraction in two consecutive time steps (“dM/M − Data”), the dashed line represents the expected mass depletion computed as , as proposed by Lapi et al. (2005; “dM/M − Lapi + 05”). The lines represent the median trends computed over the whole galaxy cluster sample. Bottom: the line shows the residuals of mass depletion computed as ((dM/M)_Data − (dM/M)_{Lapi + 05})/(dM/M)_{Lapi + 05}.
