Creation of Viscous Dark Energy by the Hubble Flow: Comparison with SNe Ia Master Sample Binned Data
Iolanda Navone, Maria Giovanna Dainotti, Elisa Fazzari +3
We study a family of cosmological models featuring dynamical dark energy (DE), based on the idea that the creation of its constituents arises from the gravitational field of the ex…
