A preliminary analysis of the energy transfer between the dark sectors of the Universe

Abstract

We study the mutual interaction between the dark sectors (dark matter and dark energy) of the Universe by resorting to the extended thermodynamics of irreversible processes and constrain the former with supernova type Ia data. As a byproduct, the present dark matter temperature results in good agreement with independent estimates of the temperature of the gas of sterile neutrinos.
