Model independent constraints on mass-varying neutrino scenarios
Urbano Franca, Massimiliano Lattanzi, Julien Lesgourgues +1
Models of dark energy in which neutrinos interact with the scalar field supposed to be responsible for the acceleration of the universe usually imply a variation of the neutrino ma…
Comment on "On curvature coupling and quintessence fine-tuning"
Urbano Franca
In this comment, we show explicitly that the phenomenological model in which the quintessence field depends linearly on the energy density of the spatial curvature can provide acce…
Dark energy, curvature, and cosmic coincidence
Urbano Franca
The fact that the energy densities of dark energy and matter are similar currently, known as the coincidence problem, is one of the main unsolved problems of cosmology. We present…
Age constraints and fine tuning in variable-mass particle models
Urbano Franca, Rogerio Rosenfeld
VAMP (variable-mass particles) scenarios, in which the mass of the cold dark matter particles is a function of the scalar field responsible for the present acceleration of the Univ…
