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…
