Ratio of the non-linear matter power spectrum at redshift zero for different cosmologies featuring either massive neutrinos or non-minimal DM over that of a reference ΛCDM cosmology with massless neutrinos. In this figure, DM parameters are chosen close to the boundary of the 95% credible intervals in the 3 × 2pt pessimistic (left plot) and optimistic (right plot) case. DM parameter values are given in Table 7.
