f(R) actions, cosmic acceleration and local tests of gravity
I. Navarro, K. Van Acoleyen
We study spherically symmetric solutions in f(R) theories and its compatibility with local tests of gravity. We start by clarifying the range of validity of the weak field expansio…
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…
Dark energy, MOND and sub-millimeter tests of gravity
I. Navarro, K. Van Acoleyen
We consider modifications of General Relativity obtained by adding the logarithm of some curvature invariants to the Einstein-Hilbert action. These non-linear actions can explain t…
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…
