local strings in generalized hybrid metric-Palatini gravity
Hilberto M. R. da Silva, Tiberiu Harko, Francisco S. N. Lobo +1
In this work we will explore local cosmic string solutions in the context of the generalized hybrid metric-Palatini theory of gravity in its scalar-tensor representation. Us…
Cosmology in scalar-tensor gravity
Tiago B. Gonçalves, João Luís Rosa, Francisco S. N. Lobo
In this work, we use reconstruction methods to obtain cosmological solutions in the recently developed scalar-tensor representation of gravity. Assuming that matter is des…

Thick branes in the scalar-tensor representation of gravity
João Luís Rosa, Matheus A. Marques, Dionisio Bazeia +1
Braneworld scenarios consider our observable universe as a brane embedded in a five-dimensional bulk. In this work, we consider thick braneworld systems in the recently proposed dy…
Weak-field regime of the generalized hybrid metric-Palatini gravity
João Luís Rosa, Francisco S. N. Lobo, Gonzalo J. Olmo
In this work we explore the dynamics of the generalized hybrid metric-Palatini theory of gravity in the weak-field, slow-motion regime. We start by introducing the equivalent scala…
Cosmic strings in generalized hybrid metric-Palatini gravity
Hilberto M. R. da Silva, Tiberiu Harko, Francisco S. N. Lobo +1
We consider the possible existence of gravitationally bound stringlike objects in the framework of the generalized hybrid metric-Palatini gravity theory, in which the gravitational…
Sudden singularities in generalized hybrid metric-Palatini cosmologies
João Luís Rosa, Francisco S. N. Lobo, Diego Rubiera-Garcia
In this work, we explore cosmological sudden singularities arising in the dynamically equivalent scalar-tensor representation of generalized hybrid metric-Palatini gravity. Using a…
