Scaling solutions in three-form cosmology
Vitor da Fonseca, Bruno J. Barros, Tiago Barreiro +1
A hybrid three-form model of dark energy is developed in order to identify scaling solutions, a long-sought feature in three-form cosmology. Exploiting Hodge dualities, the theory…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
Coupling quintessence kinetics to electromagnetism
Bruno J. Barros, Vitor da Fonseca
We propose a general model where quintessence couples to electromagnetism via its kinetic term. This novelty generalizes the linear dependence of the gauge kinetic function on ,…
Is there evidence for CIDER in the Universe?
Bruno J. Barros, Diogo Castelão, Vitor da Fonseca +3
In this work we analyze the full linear behaviour of the constrained interacting dark energy (CIDER) model, which is a conformally coupled quintessence model tailored to mimic a $Λ…
Dissecting kinetically coupled quintessence: phenomenology and observational tests
Elsa M. Teixeira, Bruno J. Barros, Vasco M. C. Ferreira +1
We investigate an interacting dark energy model which allows for the kinetic term of the scalar field to couple to dark matter via a power-law interaction. The model is characteris…
Spherical collapse in coupled quintessence with a CDM background
Bruno J. Barros, Tiago Barreiro, Nelson J. Nunes
In this work we study the growth of cold dark matter density perturbations in the nonlinear regime on a conformally coupled quintessence model in which the background is designed t…
Coupled quintessence with a CDM background: removing the tension
Bruno J. Barros, Luca Amendola, Tiago Barreiro +1
A well-known problem of the CDM model is the tension between the relatively high level of clustering, as quantified by the parameter , found in cosmic microwave background…
3-form inflation in Randall-Sundrum II
Bruno J. Barros, Nelson J. Nunes
It has been shown in the last few years that 3-form fields present viable cosmological solutions for inflation and dark energy with particular observable signatures distinct from t…
