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…
Intermediate Inflation in the Jordan-Brans-Dicke Theory
Antonella Cid, Sergio del Campo
We present an intermediate inflationary stage in a Jordan-Brans-Dicke theory. In this scenario we analyze the quantum fluctuations corresponding to adiabatic and isocurvature modes…
Presence of anisotropic pressures in Lemaître-Tolman-Bondi cosmological models
Sergio del Campo, Victor H. Cardenas, Ramon Herrera
We describe Lemaître-Tolman-Bondi cosmological models where an anisotropic pressures is considered. By using recent astronomical observations coming from supernova of Ia types we c…
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…
