Interaction in the dark sector
Sergio del Campo, Ramon Herrera, Diego Pavon
It may well happen that the two main components of the dark sector of the Universe, dark matter and dark energy, do not evolve separately but interact nongravitationally with one a…
Parameterizing the Deceleration Parameter
Diego Pavón, Ivan Duran, Sergio del Campo +1
We propose and constrain with the latest observational data three parameterizations of the deceleration parameter, valid from the matter era to the far future. They are well behave…
The generalized second law and the emergent universe
Diego Pavón, Sergio del Campo, Ramón Herrera
We explore whether the generalized second law of thermodynamics is fulfilled in the transition from a generic initial Einstein static phase to the inflationary phase, with constant…
Three thermodynamically-based parametrizations of the deceleration parameter
Sergio del Campo, Ivan Duran, Ramon Herrera +1
We propose, and constrain with the latest observational data, three model-independent parametrizations of the cosmic deceleration parameter . They are well behaved and stay f…
On the Stability of Jordan-Brans-Dicke Static Universe
Sergio del Campo, Ramon Herrera, Pedro Labrana
In this work we study the stability of the Jordan-Brans-Dicke (JBD) static universe. This is motivated by the possibility that the universe might have started out in an asymptotica…
Evolving Lorentzian wormholes supported by phantom matter and cosmological constant
Mauricio Cataldo, Sergio del Campo, Paul Minning +1
In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made of phantom energy in the presence of a cosmological constant. We derive analytical…
