Title |
Testing Extended theories of gravity: perspectives from the astrometric point of view | |||||
| Co-authors | ||||||||
|
Abstract |
Extended Theories of Gravity are invoked not only to provide a possible route to a more complete gravity theory, but also to explain several cosmological and astrophysical phenomena. The possibility of testing this class of gravity theories with astrometric measurements is explored, reviewing both its present possibilities and its future perspectives. |

Title |
GAME - A space mission for relativistic tests around the Earth | |||||
| Co-authors | ||||||||

Abstract |
GAME (Gravitation Astrometric Measurement Experiment) is a concept for a satellite whose main goal is the estimation of the PPN parameters \gamma and \beta by means of a modern rendition from space of the classical Dyson-Eddington-Davidson eclipse experiment. The same measurement concept can be applied at different scales, from that of a small mission, where we expect to reach an accuracy level of 10^-6/10^-7 on \gamma and of 10^-4 on \beta, to that of a medium one, with accuracy of 10^-8 and 10^-6 respectively. |
