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…
Vacuum energy and cosmological constant in QFT in curved spacetime
Joan Solà Peracaula, Cristian Moreno-Pulido
The cosmological constant term (CC), , is a pivotal ingredient in the standard model of cosmology or CDM, but it is a rigid quantity for the entire cosmic history. This is un…
The dynamics of vacuum, gravity and matter: Implications on the fundamental constants
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…
String-inspired running-vacuum cosmology, quantum corrections and the current cosmological tensions
Nick E. Mavromatos, Joan Solà Peracaula, Adrià Gómez-Valent
In the context of a string-inspired running vacuum model (RVM) of cosmology with anomalies and torsion-induced axion-like fields, we discuss quantum corrections to the correspondin…
Running vacuum in QFT in FLRW spacetime: The dynamics of from the quantized matter fields
Cristian Moreno-Pulido, Joan Sola Peracaula, Samira Cheraghchi
Phenomenological work in the last few years has provided significant support to the idea that the vacuum energy density (VED) is a running quantity with the cosmological evolution…
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…
Equation of state of the running vacuum
Cristian Moreno-Pulido, Joan Sola Peracaula
Recent studies of quantum field theory in FLRW spacetime suggest that the cause of the speeding up of the universe is the running vacuum (RV). Appropriate renormalization of the en…
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…
Quantum gravity phenomenology at the dawn of the multi-messenger era -- A review
A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
Renormalized without terms
Cristian Moreno-Pulido, Joan Sola Peracaula
The cosmological constant term, , in Einstein's equations has been for three decades a building block of the concordance or standard CDM model of cosmology. Although the latt…
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…
Running vacuum interacting with dark matter or with running gravitational coupling. Phenomenological implications
Joan Sola Peracaula
The cosmological term, , in Einstein's equations is an essential ingredient of the `concordance' CDM model of cosmology. In this mini-review presentation, we assess the possi…
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
