Evolution of density perturbations in decaying vacuum cosmology: The case of non-zero perturbations in the cosmological term
H. A. Borges, S. Carneiro, J. C. Fabris
We extend the results of a previous paper where a model of interacting dark energy, with a cosmological term decaying linearly with the Hubble parameter, is tested against the obse…
Evolution of density perturbations in decaying vacuum cosmology
H. A. Borges, S. Carneiro, J. C. Fabris +1
We study cosmological perturbations in the context of an interacting dark energy model, in which the cosmological term decays linearly with the Hubble parameter, with concomitant m…
Supernova constraints on decaying vacuum cosmology
S. Carneiro, C. Pigozzo, H. A. Borges +1
There is mounting observational evidence that the expansion of our Universe is undergoing a late-time acceleration. Among many proposals to describe this phenomenon, the cosmologic…
