Observational constraints on the free parameters of an interacting Bose-Einstein gas as a dark-energy model
Hiram E. Lucatero--Villaseñor, German Izquierdo, Jaime Besprosvany
Dark energy is modelled by a Bose-Einstein gas of particles with an attractive interaction. It is coupled to cold dark matter, within a flat universe, for the late-expansion descri…
Coupled Dark Energy field variation
Roberto Carlos García-Zúñiga, Germán Izquierdo
The variation of the dark energy field is found under the assumption that the dark energy is parametric and interacts with the cold dark matter. Considering that the variation of t…
Coincidence problem within dark energy as a coupled self-interacting Bose-Einstein gas
Jaime Besprosvany, German Izquierdo
A late accelerated expansion of the Universe is obtained from non-relativistic particles with a short-range attractive interaction, and low enough temperature to produce a Bose-Ein…
Late evolution of relic gravitational waves in coupled dark energy models
Maria Luisa Sosa Almazan, German Izquierdo
In this paper we study the late evolution of Relic Gravitational Waves in coupled dark energy models, where dark energy interacts with cold dark matter. Relic Gravitational Waves a…
Limits on the parameters of the equation of state for interacting dark energy
German Izquierdo, Diego Pavon
Under the assumption that cold dark matter and dark energy interact with each other through a small coupling term, , we constrain the parameter space of the equation of state $w…
