The 4D Einstein-Gauss-Bonnet Theory of Gravity: A Review
Pedro G. S. Fernandes, Pedro Carrilho, Timothy Clifton +1
We review the topic of 4D Einstein-Gauss-Bonnet gravity, which has been the subject of considerable interest over the past two years. Our review begins with a general introduction…
Black Holes in the Scalar-Tensor Formulation of 4D Einstein-Gauss-Bonnet Gravity: Uniqueness of Solutions, and a New Candidate for Dark Matter
Pedro G. S. Fernandes, Pedro Carrilho, Timothy Clifton +1
In this work we study static black holes in the regularized 4D Einstein-Gauss-Bonnet theory of gravity; a shift-symmetric scalar-tensor theory that belongs to the Horndeski class.…
Observational Constraints on the Regularized 4D Einstein-Gauss-Bonnet Theory of Gravity
Timothy Clifton, Pedro Carrilho, Pedro G. S. Fernandes +1
In this paper we study the observational constraints that can be imposed on the coupling parameter, , of the regularized version of the 4-dimensional Einstein-Gauss-Bonnet…
Derivation of Regularized Field Equations for the Einstein-Gauss-Bonnet Theory in Four Dimensions
Pedro G. S. Fernandes, Pedro Carrilho, Timothy Clifton +1
We propose a regularization procedure for the novel Einstein-Gauss-Bonnet theory of gravity, which produces a set of field equations that can be written in closed form in four dime…
Non-linear effects in early Universe cosmology
Pedro Carrilho
In this thesis, we discuss several instances in which non-linear behaviour affects cosmological evolution in the early Universe. We begin by reviewing the standard cosmological mod…
Two-scalar-field model for the interaction of dark energy and dark matter
Orfeu Bertolami, Pedro Carrilho, Jorge Páramos
In this paper, we study the effects of an interaction between dark matter and dark energy through a two scalar field model with a potential , where i…
