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…
Difficulties in reconciling non-negligible differences between the local and cosmological values of the gravitational coupling in extended Brans-Dicke theories
Adrià Gómez-Valent, Prajwal Hassan Puttasiddappa
Recent studies by Solà Peracaula, Gómez-Valent, de Cruz Pérez and Moreno-Pulido (2019,2020) have pointed out the intriguing possibility that Brans-Dicke cosmology with constant vac…
Running vacuum against the and tensions
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez +1
The cosmological term, , was introduced years ago by Einstein in his gravitational field equations. Whether is a rigid quantity or a dynamical variable in cosmology ha…
