Brans-Dicke-like field for co-varying and : observational constraints
J. Bezerra-Sobrinho, R. R. Cuzinatto, L. G. Medeiros +1
Ref. [Symmetry 15 (2023) 709] introduced a Brans-Dicke-like framework wherein the scalar field is composed of both and which, for this reason, co-vary according to $c^{…
Gravitational Waves Emission in Quadratic Gravity: longitudinal modes, angular momentum emission, and positivity of the radiated power
Matheus F. S. Alves, R. R. Cuzinatto, C. A. M. de Melo +2
In this paper, the emission of gravitational waves in quadratic gravity theory is examined. The wave equations for massless and massive perturbations are derived, followed by the c…
Inflationary dynamics in modified gravity models
R. R. Cuzinatto, L. G. Medeiros
Higher-order theories of gravity are a branch of modified gravity wherein the geometrodynamics of the four-dimensional Riemannian manifold is determined by field equations involvin…
Viable wormhole solution in Bopp-Podolsky electrodynamics
D. A. Frizo, C. A. M. de Melo, L. G. Medeiros +1
Following a recent approach in which the gravitational field equations in curved spacetimes were presented in the Bopp--Podolsky electrodynamics, we obtained an approximate and sph…
Second-order corrections to Starobinsky inflation
G. Rodrigues-da-Silva, L. G. Medeiros
Higher-order theories of gravity are extensions to general relativity (GR) motivated mainly by high-energy physics searching for GR ultraviolet completeness. They are characterized…
Gravitational waves from inspiraling black holes in quadratic gravity
Matheus F. S. Alves, Luís F. M. A. M. Reis, L. G. Medeiros
We peform a study of gravitational waves emitted by inspiraling black holes in the context of quadratic gravity. By linearizing the field equations around a flat background, we dem…
