Gravitational wave propagation in generalized hybrid metric-Palatini gravity
Cláudio Gomes, João Luís Rosa, Miguel A. S. Pinto
In this work we analyze the propagation properties of gravitational waves in the hybrid metric-Palatini gravity theory. We introduce the scalar-tensor representation of the theory…
CDM-like evolution in Einstein-scalar-Gauss-Bonnet gravity
Miguel A. S. Pinto, João Luís Rosa
In this work, we analyze the Einstein-scalar-Gauss-Bonnet (EsGB) theory of gravity in a cosmological context using the formalism of dynamical systems. We obtain the equations of mo…
Dynamical reconstruction of the CDM model in the scalar-tensor representation of gravity
Adam Z. Kaczmarek, João Luís Rosa, Dominik Szczȩśniak
Motivated by the growing interest in the nonmetricity-matter couplings, we develop the scalar-tensor formulation of recently introduced gravity, where is the nonmetric…
Dynamical reconstruction of the CDM model in hybrid metric-Palatini gravity
João Luís Rosa
In this work, we apply the formalism of dynamical systems to analyze the viability of the CDM model in a generalized form of the hybrid metric-Palatini gravity theory written in…
Sudden cosmological singularities in Aether scalar-tensor theories
João Luís Rosa, Tom Zlosnik
In this work we analyze the possibility of sudden cosmological singularities, also known as type-II singularities, in the background of a Friedmann-Lemaître-Robertson-Walker (FLRW)…
Junction conditions in gravity theories with extra scalar degrees of freedom
João Luís Rosa
In this work we present a general method to obtain the junction conditions of modified theories of gravity whose action can be written in the form , wher…
Dynamical system analysis of cosmological evolution in the Aether scalar tensor theory
João Luís Rosa, Tom Zlosnik
The Aether Scalar Tensor (AeST) theory is an extension of General Relativity (GR), proposed for addressing galactic and cosmological observations without dark matter.The action for…
