LTB solutions in Newtonian gauge: from strong to weak fields
Karel Van Acoleyen
Lemaitre-Tolman-Bondi (LTB) solutions are used frequently to describe the collapse or expansion of spherically symmetric inhomogeneous mass distributions in the Universe. These exa…
Long distance modifications of gravity in four dimensions
I. Navarro, K. Van Acoleyen
We discuss some general characteristics of modifications of the 4D Einstein-Hilbert action that become important for low space-time curvatures. In particular we focus on the chamel…
Modified gravity, Dark Energy and MOND
Ignacio Navarro, Karel Van Acoleyen
We propose a class of actions for the spacetime metric that introduce corrections to the Einstein-Hilbert Lagrangian depending on the logarithm of some curvature scalars. We show t…
On the Newtonian limit of Generalized Modified Gravity Models
Ignacio Navarro, Karel Van Acoleyen
We consider the Newtonian limit of modified theories of gravity that include inverse powers of the curvature in the action in order to explain the cosmic acceleration. It has been…
