Stringy Running Vacuum Model and current Tensions in Cosmology
Adrià Gómez-Valent, Nick E. Mavromatos, Joan Solà Peracaula
We discuss the potential alleviation of both the Hubble and the growth of galactic structure data tensions observed in the current epoch of Cosmology in the context of the so-calle…
Dynamical dark energy versus const. in light of observations
Joan Sola Peracaula, Javier de Cruz Perez, Adria Gomez-Valent
After about two decades of the first observational papers confirming the accelerated expansion of the universe, we are still facing the question whether the cause of it is a rigid…
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…
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…
