Gravitational Lensing and f(R) theories in the Palatini approach
Matteo Luca Ruggiero
We investigate gravitational lensing in the Palatini approach to the f(R) extended theories of gravity. Starting from an exact solution of the f(R) field equations, which correspon…

Solar System tests of some models of modified gravity proposed to explain galactic rotation curves without dark matter
Lorenzo Iorio, Matteo Luca Ruggiero
We consider the recently estimated corrections Δ\dot\varpi to the Newtonian/Einsteinian secular precessions of the longitudes of perihelia \varpi of several planets of the Solar Sy…

Mapping Cartesian Coordinates into Emission Coordinates: some Toy Models
Matteo Luca Ruggiero, Angelo Tartaglia
After briefly reviewing the relativistic approach to positioning systems based on the introduction of the emission coordinates, we show how explicit maps can be obtained between th…
