Heating rate induced by DM secondary particles in Coma as predicted by the three DM models with Mχ = 9 GeV, Mχ = 60 GeV and Mχ = 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) ∝ nth(r) and smooth DM profiles, without considering the effect of substructures.
