Interacting dark matter and cosmic acceleration
(EDP SciencesSocietà Italiana di FisicaSpringer Berlin Heidelberg, 2020)
We study the effect of an explicit interaction between two scalar fields components describing dark matter in the context of a recent proposal framework for interaction. We find that, even assuming a very small coupling, ...
Challenging matter creation models in the phantom divide
(American Physical Society, 2020)
We perform a study both statistical and theoretical for cosmological models of matter creation and their ability to describe effective phantom models of dark energy. Such models are beyond the ΛCDM model since the resulting ...
