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…
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…
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…
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…
