“…Earlier studies on DM/DE interaction used WMAP, and additionally other data sets on CMB temperature anisotropies, to set upper limits on the strength of the DM/DE coupling [272,274,152,384,413,386,295,334,118,119,175,177,178] or to constrain the cross-section of DM/DE interactions [416]. More recently, Planck CMB data have been used to constrain interacting models with different kernels discussed in the literature: Q = Hξ 1 ρ c [118,387], Q = Hξ 2 ρ d [118,334,420,421,76], [118,143,315]. Other couplings have also been discussed; [335] has shown that the data provides a moderate Bayesian evidence in favor of an interacting vacuum model.…”
