Testing cosmological structure formation in a Unified Dark Matter-Energy model with fast transition
Diogo Castelão, Alberto Rozas-Fernández, Ismael Tereno
Unified Dark Matter-Energy models (UDM), a class of models where dark matter and dark energy exist as a single cosmological fluid, are an alternative approach to CDM. In this wo…
Cosmological constraints on a unified dark matter-energy scalar field model with fast transition
Iker Leanizbarrutia, Alberto Rozas-Fernández, Ismael Tereno
We test the viability of a single fluid cosmological model containing a transition from a dark-matter-like regime to a dark-energy-like regime. The fluid is a k-essence scalar fiel…
Phenomenology of Unified Dark Matter models with fast transition
Alberto Rozas-Fernández, Marco Bruni, Ruth Lazkoz
A fast transition between a standard matter-like era and a late CDM-like epoch generated by a single Unified Dark Matter component can explain the observed acceleration of the U…
Interacting holographic tachyon model of dark energy
Alberto Rozas-Fernández, David Brizuela, Norman Cruz
We propose a holographic tachyon model of dark energy with interaction between the components of the dark sector. The correspondence between the tachyon field and the holographic d…
Interacting non-minimally coupled canonical, phantom and quintom models of holographic dark energy in non-flat universe
M R Setare, Alberto Rozas-Fernández
Motivated by our recent work \cite{set1}, we generalize this work to the interacting non-flat case. Therefore in this paper we deal with canonical, phantom and quintom models, with…
Quantum cosmic models and thermodynamics
Pedro F. González-Díaz, Alberto Rozas-Fernández
The current accelerating phase of the evolution of the universe is considered by constructing most economical cosmic models that use just general relativity and some dominating qua…
