Determinantal Born-Infeld Coupling of Gravity and Electromagnetism
Victor I. Afonso, Cecilia Bejarano, Rafael Ferraro +1
We study a Born-Infeld inspired model of gravity and electromagnetism in which both types of fields are treated on an equal footing via a determinantal approach in a metric-affine…
An infinite class of exact rotating black hole metrics of modified gravity
Victor I. Afonso, Gerardo Mora-Pérez, Gonzalo J. Olmo +2
We build an infinite class of exact axisymmetric solutions of a metric-affine gravity theory, namely, Eddington-inspired Born-Infeld gravity, coupled to an anisotropic fluid as a m…
Compact scalar field solutions in EiBI gravity
Victor I. Afonso
We discuss exact scalar field solutions describing gravitating compact objects in the Eddington-inspired Born-Infeld gravity (EiBI), a member of the class of (metric-affine formula…
New scalar compact objects in Ricci-based gravity theories
Victor I. Afonso, Gonzalo J. Olmo, Emanuele Orazi +1
Taking advantage of a previously developed method, which allows to map solutions of General Relativity into a broad family of theories of gravity based on the Ricci tensor (Ricci-b…
A correspondence between modified gravity and General Relativity with scalar fields
Victor I. Afonso, Gonzalo J. Olmo, Emanuele Orazi +1
We describe a novel procedure to map the field equations of nonlinear Ricci-based metric-affine theories of gravity, coupled to scalar matter described by a given Lagrangian, into…
Mapping nonlinear gravity into General Relativity with nonlinear electrodynamics
Victor I. Afonso, Gonzalo J. Olmo, Emanuele Orazi +1
We show that families of nonlinear gravity theories formulated in a metric-affine approach and coupled to a nonlinear theory of electrodynamics can be mapped into General Relativit…
