Abstract EN
Up-to-date estimates of the cosmological parameters are presented as a result of numerical simulations of cosmic microwave background and large scale structure, considering a flat Universe in which the dark matter is made entirely or partly of mirror matter, and the primordial perturbations are scalar adiabatic and in linear regime.
A statistical analysis using the Markov Chain Monte Carlo method allows to obtain constraints of the cosmological parameters.
As a result, we show that a Universe with pure mirror dark matter is statistically equivalent to the case of an admixture with cold dark matter.
The upper limits for the ratio of the temperatures of ordinary and mirror sectors are around 0.3 for both the cosmological models, which show the presence of a dominant fraction of mirror matter, 0.06≲Ωmirrorh2≲0.12.
