Higher neutrino mass allowed if Cold Dark Matter and Dark Energy are coupled
G. La Vacca, S. A. Bonometto, L. P. L. Colombo
Cosmological limits on neutrino masses are softened, by more than a factor 2, if Cold Dark Matter (CDM) and Dark Energy (DE) are coupled. In turn, a neutrino mass yielding up…
Gravitational Lensing Constraints on Dynamical and Coupled Dark Energy
G. La Vacca, L. P. L. Colombo
Upcoming Weak Lensing (WL) surveys can be used to constrain Dark Energy (DE) properties, namely if tomographic techniques are used to improve their sensitivity. In this work, we us…
Dark Matter - Dark Energy coupling biasing parameter estimates from CMB data
Giuseppe La Vacca, Loris P. L. Colombo, Luca Vergani +1
When CMB data are used to derive cosmological parameters, their very choice does matter: some parameter values can be biased if the parameter space does not cover the "true" model.…
