BD-CDM and Running Vacuum Models: Theoretical background and current observational status
Javier de Cruz Perez, Joan Sola Peracaula, Adria Gomez-Valent +1
We present an analysis of the Brans-Dicke cosmological model with a cosmological constant and cold dark matter (BD-CDM). We find that the BD-CDM is favored by the overall cos…
Signs of Dynamical Dark Energy in Current Observations
Joan Sola Peracaula, Adria Gomez-Valent, Javier de Cruz Perez
Investigations on dark energy (DE) are currently inconclusive about its time evolution. Hints of this possibility do however glow now and then in the horizon. Herein we assess the…
Brans-Dicke cosmology mimicking running vacuum
Javier de Cruz Perez, Joan Sola
Brans-Dicke (BD) cosmology is reconsidered from an approach in which the model can be formulated in CDM form, but at the expense of replacing the rigid cosmological constant …
Vacuum dynamics in the Universe versus a rigid const
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez
In this year, in which we celebrate 100 years of the cosmological term, , in Einstein's gravitational field equations, we are still facing the crucial question whether is tr…
