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…

Observational constraints on late-time Lambda(t) cosmology
S. Carneiro, M. A. Dantas, C. Pigozzo +1
The cosmological constant, i.e., the energy density stored in the true vacuum state of all existing fields in the Universe, is the simplest and the most natural possibility to desc…

Non-singular inflation with vacuum decay
Saulo Carneiro
On the basis of a semi-classical analysis of vacuum energy in an expanding spacetime, we describe a non-singular cosmological model in which the vacuum density decays with time, wi…
