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…
