String-inspired running-vacuum cosmology, quantum corrections and the current cosmological tensions
Nick E. Mavromatos, Joan Solà Peracaula, Adrià Gómez-Valent
In the context of a string-inspired running vacuum model (RVM) of cosmology with anomalies and torsion-induced axion-like fields, we discuss quantum corrections to the correspondin…
Running vacuum in the Universe: phenomenological status in light of the latest observations, and its impact on the and tensions
Joan Sola Peracaula, Adria Gomez-Valent, Javier de Cruz Perez +1
A substantial body of phenomenological and theoretical work over the last few years strengthens the possibility that the vacuum energy density (VED) of the universe is dynamical, a…
Coupled and uncoupled early dark energy, massive neutrinos and the cosmological tensions
Adrià Gómez-Valent, Ziyang Zheng, Luca Amendola +2
Some cosmological models with non-negligible dark energy fractions in particular windows of the pre-recombination epoch are capable of alleviating the Hubble tension quite efficien…
from cosmic chronometers and Type Ia supernovae, with Gaussian processes and the weighted polynomial regression method
Adrià Gómez-Valent, Luca Amendola
We derive new constraints on the Hubble parameter using the available data on from cosmic chronometers (CCH), and the Hubble rate data points from the supernovae of Ty…
Dynamical dark energy: scalar fields and running vacuum
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez
Recent analyses in the literature suggest that the concordance CDM model with rigid cosmological term, const., may not be the best description of the cosmic acceleration. Th…
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…
