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…
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…
Warm-Logamediate inflationary universe model
Ramon Herrera, Marco Olivares
Warm inflationary universe models in the context of logamediate expansion are studied. General conditions required for these models to be realizable and discussed. This study is do…
