Cosmological Constraints on Mirror Matter Parameters

Figure 3

Evolution of the density perturbations of the different components of a mirror Universe: cold dark matter (solid), ordinary baryons (dot-dashed), ordinary photons (dotted), mirror baryons (long dashed), and mirror photons (dashed). The models correspond to the parameters of Table 2 obtained with the CMB and LSS data. (a) Pure mirror case at the scale log𝑘(Mpc⁻¹)=−0.5. (b) Pure mirror case at the scale log𝑘(Mpc⁻¹)=−1.0. (c) Mixed mirror-CDM case at the scale log𝑘(Mpc⁻¹)=−0.5. (d) Mixed mirror-CDM case at the scale log𝑘(Mpc⁻¹)=−1.0.
