Mass-Varying Neutrinos from an Inverse Symmetron
Mainak Baidya, Ãyvind Christiansen, Vitor da Fonseca +2
Neutrinos enter cosmology in different ways and are constrained by distinct observational probes across different epochs: as a relativistic species at high redshift, as a massive b…

Scaling solutions in three-form cosmology
Vitor da Fonseca, Bruno J. Barros, Tiago Barreiro +1
A hybrid three-form model of dark energy is developed in order to identify scaling solutions, a long-sought feature in three-form cosmology. Exploiting Hodge dualities, the theory…

The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
