Geometrical optics in the universe with dark matter domination
The cosmological Friedmann model has been generalized for the epoch of dark matter domination. Moreover, its equation of state was chosen in a new - non-stationary form. Based on the process of light propagation in such a metric, its refractive index was found which turned out to quantity constant (more precisely, depending on the era of the end of dominance of dark matter) and the possible effect of a burst of incoming radiation was predicted.
