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…
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…
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…
Closed inflationary universe with tachyonic field
Leonardo Balart, Sergio del Campo, Ramon Herrera +1
In this article we study closed inflationary universe models by using a tachyonic field theory. We determine and characterize the existence of an universe with , and which de…
