XCDM: a running vacuum strategy for crossing the phantom divide
Joan Solà Peracaula, Adrià Gómez-Valent, Alex González-Fuentes
Composite dynamical dark energy (DDE) has recently been explored as an efficient way to help cure cosmological tensions through the so-called XCDM model (Gomez-Valent & Solà Per…
Dynamical Dark Energy models in light of the latest observations
Javier de Cruz Pérez, Adrià Gómez-Valent, Joan Solà Peracaula
In this paper, we study several models and parameterizations of dynamical dark energy (DE) that have been studied already in the past, in conjunction with the recently proposed mod…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Composite running vacuum in the Universe: implications on the cosmological tensions
Joan Solà Peracaula
The possibility that the vacuum energy density (VED) could be time dependent in the expanding Universe is intuitively more reasonable than just a rigid cosmological constant for th…
Running vacuum versus Holographic dark energy: a cosmographic comparison
Mehdi Rezaei, Joan Sola Peracaula
We perform a comparative study of different types of dynamical dark energy models (DDES) using the cosmographic method. Among the models being examined herein we have the Running V…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
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…
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…
Density perturbations for running vacuum: a successful approach to structure formation and to the -tension
Adrià Gómez-Valent, Joan Solà Peracaula
Recent studies suggest that dynamical dark energy (DDE) provides a better fit to the rising affluence of modern cosmological observations than the concordance model (CDM) with a…
Possible signals of vacuum dynamics in the Universe
Joan Sola Peracaula, Javier de Cruz Perez, Adria Gomez-Valent
We study a generic class of time-evolving vacuum models which can provide a better phenomenological account of the overall cosmological observations as compared to the CDM. Amon…
