Evolving Lorentzian wormholes supported by phantom matter with constant state parameters
Mauricio Cataldo, Pedro Labrana, Sergio del Campo +2
In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made out of phantom energy. We show that this exotic source can support the existence of…
Toward a solution of the coincidence problem
Sergio del Campo, Ramon Herrera, Diego Pavon
The coincidence problem of late cosmic acceleration constitutes a serious riddle with regard to our understanding of the evolution of the Universe. Here we argue that this problem…
Open Inflationary Universes in Gauss-Bonnet Brane Cosmology
Sergio del Campo, Ramon Herrera, Joel Saavedra
In this article, we study a type of one-field approach for open inflationary universe scenario in the context of braneworld models with a Gauss-Bonnet correction term. For a one-bu…
Curvaton field and intermediate inflationary universe model
Sergio del Campo, Ramon Herrera
The curvaton in an intermediate inflationary universe model is studied. This study has allowed us to find some interesting constraints on different parameters that appear in the mo…
Warm inflation in the DGP brane-world model
Sergio del Campo, Ramon Herrera
Warm inflationary universe models on a warped Dvali-Gabadadze-Porrati brane are studied. General conditions required for these models to be realizable are derived and discussed. By…
Cosmological perturbations in warm inflationary models with viscous pressure
Sergio del Campo, Ramon Herrera, Diego Pavon
Scalar and tensorial cosmological perturbations generated in warm inflationary scenarios whose matter-radiation fluid is endowed with a viscous pressure are considered. Recent obse…
