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…
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…
First evidence of running cosmic vacuum: challenging the concordance model
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez
Despite the fact that a rigid -term is a fundamental building block of the concordance CDM model, we show that a large class of cosmological scenarios with dynamical vacuum e…
