Heating rate induced by DM secondary particles in Coma as predicted by the three DM models with M_χ = 9 GeV, M_χ = 60 GeV and M_χ = 500 GeV for (solid), τ ^±  (dashed), W^± (dot-dashed) compositions. We consider an NFW DM profile (green, blue, and red peaking curves for 9, 60, and 500 GeV respectively) and a cored DM profile (green, blue and red flattening curves for 9, 60, and 500 GeV respectively). The values of σV and B₀ for the different models are the same as those used in Fig. 2. The solid black curve shows the bremsstrahlung cooling rate of the intra-cluster gas at a temperature of 8.2 keV. The results are obtained using B(r) ∝ n_th(r) and smooth DM profiles, without considering the effect of substructures.
