Background history and cosmic perturbations for a general system of self-conserved dynamical dark energy and matter
Adria Gomez-Valent, Elahe Karimkhani, Joan Sola
We determine the Hubble expansion and the general cosmic perturbations equations for a general system consisting of self-conserved matter and self-conserved dark energy (DE). While…
Hints of dynamical vacuum energy in the expanding Universe
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez
Recently there have been claims on model-independent evidence of dynamical dark energy. Herein we consider a fairly general class of cosmological models with a time-evolving cosmol…
Vacuum models with a linear and a quadratic term in H: structure formation and number counts analysis
Adria Gomez-Valent, Joan Sola
We focus on the class of cosmological models with a time-evolving vacuum energy density of the form , where is the Hubble rate. Higher powers of coul…
The cosmology: from inflation to dark energy through running
Joan Sola, Adria Gomez-Valent
Perhaps the deepest mystery of our accelerating Universe in expansion is the existence of a tiny and rigid cosmological constant, . Its size is many orders of magnitude below th…
