Abstract
A new concept has been proposed and elaborated to account for recent observations deviating from ΛCDM and ΛWDM. Using an intermediate energy conversion mechanism in the expanding universe and assuming three neutrino families with identical mass, a neutrino mass of eV/c2 has been found as well as a natural explanation for the difference in Hubble constant as measured by WMAP/Planck and obtained from LSS data. The value for the effective number of neutrinos at the time of decoupling is compatible with the Planck result. The age of the universe is slightly younger at Gyr. At late times, the closure parameter for the neutrino radiation drastically increases but still remains well below that of the baryons , among other energy contributions.
Highlights
The six parameter ΛCDM model [1], where CDM stands for Cold Dark Matter and Λ refers to the cosmological constant, has long been regarded as the standard model of modern cosmology
A new concept has been proposed for the generation of dark matter, based on the nucleon with its characteristic radius and potential, which is thought to be representative of an underlying mechanism converting energy from the expanding universe into dark matter and radiation
Energy build-up first accounted for the mass to be generated and was subject to a decay which has been assumed to be mediated by the weak interaction
Summary
The six parameter ΛCDM model [1], where CDM stands for Cold Dark Matter and Λ refers to the cosmological constant, has long been regarded as the standard model of modern cosmology. Despite its success in explaining many features of the Cosmic Microwave Background (CMB) power spectrum [2] among others, increasingly precise data from observations are more and more at odds with it. In the ΛCDM scenario, an important role is played by cold dark matter. Many interesting scenarios have been proposed to explain the true nature of CDM, in-
