Could the dynamics of the Universe be influenced by what is going on inside black holes?

P. P. Avelino

We investigate the potential impact of mass inflation inside black holes on the dynamics of the Universe, considering a recent reformulation of general relativity, proposed in [1],…

Vacuum energy sequestering and cosmic dynamics

P. P. Avelino

We explicitly compute the dynamics of closed homogeneous and isotropic universes permeated by a single perfect fluid with a constant equation of state parameter in the context…

Center of mass, spin supplementary conditions, and the momentum of spinning particles

L. Filipe Costa, José Natário

We discuss the problem of defining the center of mass in general relativity and the so-called spin supplementary condition. The different spin conditions in the literature, their p…

Black hole solutions of gravity theories with nonminimal coupling between matter and curvature

Orfeu Bertolami, Mariano Cadoni, Andrea Porru

We study black hole solutions in an extension of General Relativity (GR) with an explicit non-minimal coupling between matter and curvature. General black hole solutions satisfying…

Viability of nonminimally coupled f (R) gravity

Orfeu Bertolami, Jorge Páramos

In this work we explore the viability of nonminimally coupled matter- curvature gravity theories, namely the conditions required for the absence of tachyon instabilities and ghost…

Modelling the nongravitational acceleration during Cassini's gravitation experiments

O. Bertolami, F. Francisco, P. J. S. Gil +1

In this paper we present a computation of the thermally generated acceleration of the Cassini probe during its solar conjunction experiment, obtained from a model of the spacecraft…

A perturbative approach for the study of compatibility between nonminimally coupled gravity and Solar System experiments

Orfeu Bertolami, Riccardo March, Jorge Páramos

We develop a framework for constraining a certain class of theories of nonminimally coupled (NMC) gravity with Solar System observations.
