Searches for extensions to General Relativity: from the Solar System to our Galactic Center

Aurelien Hees (UCLA) - May 1, 2017 at 12:10 pm

In this talk, we will review the basic principles of General Relativity and give motivations to search for alternative theories of gravitation. Then, we will review some of the very recent tests of the gravitation theory performed in the Solar System insisting on their implications. We will also discuss how the monitoring of short-period stars orbiting the supermassive black hole in our Galactic Center can be used to test General Relativity. Recent results in the fifth force formalism will be presented and plans to measure relativistic effects during the closest approach of the star S0-2 in 2018 will also be developed.

The seminar will be held in 131A Campbell Hall.
