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…
Non-canonical 3-form dark energy
Vitor da Fonseca, Bruno J. Barros, Tiago Barreiro +1
In this study, we meticulously construct a 3-form Lagrangian designed to mimic the dynamics of both dust matter in the past and dark energy driving the acceleration in the present…
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…
Wormholes with matter haunted by conformally coupled ghosts
Bruno J. Barros, Álvaro de la Cruz-Dombriz, Francisco S. N. Lobo
In this work, we present novel analytical solutions for static and spherically symmetric wormhole geometries threaded by an anisotropic distribution of matter conformally coupled t…
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…
Static spherically symmetric three-form stars
Bruno J. Barros, Zahra Haghani, Tiberiu Harko +1
We consider interior static and spherically symmetric solutions in a gravity theory that extends the standard Hilbert-Einstein action with a Lagrangian constructed from a three-for…
Testing gravity with redshift space distortions
Bruno J. Barros, Tiago Barreiro, Tomi Koivisto +1
A Bayesian statistical analysis using redshift space distortions data is performed to test a model of Symmetric Teleparallel Gravity where gravity is non-metrical. The cosmological…
Black hole and naked singularity geometries supported by three-form fields
Bruno J. Barros, Bogdan Dǎnilǎ, Tiberiu Harko +1
We investigate static and spherically symmetric solutions in a gravity theory that extends the standard Hilbert-Einstein action with a Lagrangian constructed from a three-form fiel…
Bouncing cosmology in gravity by order reduction
Bruno J. Barros, Elsa M. Teixeira, Daniele Vernieri
A bouncing universe is a viable candidate to solve the initial singularity problem. Here we consider bouncing solutions in the context of gravity by using an ord…
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…
Kinetically coupled dark energy
Bruno J. Barros
The main goal of this work is to propose a generalized model of interacting dark energy which allows for the kinetic term of a scalar field to couple to the matter species a priori…
Wormhole geometries supported by three-form fields
Bruno J. Barros, Francisco S. N. Lobo
In this work, we find novel static and spherically symmetric wormhole geometries using a three-form field. By solving the gravitational field equations, we find a variety of analyt…
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…
