Abstract: We use the framework of a recently proposed model of reduced relativistic gas (RRG) to obtain the bounds for Ω's of Dark Matter and Dark Energy (in the present case, a cosmological constant), taking into consideration an arbitrary warmness of Dark Matter. An equivalent equation of state has been used by Sakharov to predict the oscillations in the matter power spectrum. Two kind of tests are accounted for in what follows, namely the ones coming from the dynamics of the conformal factor of the homogeneous and is… Show more

“…As it was expected from the previous works on this model [21,22,25], the RRG shows the behaviour which is intermediate between radiation and dust and approaches one or another depending on the value of warmness parameter. We have shown that this feature can be extended to the simplest anisotropic Bianchi-I model.…”

“…In the nowadays universe the value of Γ is very small implying in a very small value of Ω 0 an . The warmness b today is bounded from above by approximately 0.001 for the dominating fluid, namely for the dark matter [25]. Indeed, in the early universe when Ω 0 an was significant, the warmness could have a large value.…”

“…At the same time, we have a very strong positive signal from the analysis of the LSS data. The power spectrum tests are almost not sensible to the G(µ) running and, exactly in this case, we meet an alternative to ΛCDM in the zero-order approximation 14 . Finally, we can conclude that there is still some (albeit they can be evaluated to be small) chance that the vacuum effects of QFT in an external gravitational field play more significant role in our Universe that we usually think.…”
