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…
Boosting MonteCarlo sampling with a non-Gaussian fit
Luca Amendola, Adrià Gómez-Valent
We propose a new method, called MonteCarlo Posterior Fit, to boost the MonteCarlo sampling of likelihood (posterior) functions. The idea is to approximate the posterior function by…
Brans-Dicke cosmology with a - term: a possible solution to CDM tensions
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez +1
We present a full-fledged analysis of Brans-Dicke cosmology with a cosmological constant and cold dark matter (BD-CDM for short). We extend the scenarios where the current cosmo…
Brans-Dicke gravity with a cosmological constant smoothes out CDM tensions
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez +1
We analyze Brans-Dicke gravity with a cosmological constant, , and cold dark matter (BD-CDM for short) in the light of the latest cosmological observations on distant superno…
