Measuring the effects of General Relativity at the Galactic Center with Future Extremely Large Telescopes
Tuan Do, Aurelien Hees, Arezu Dehghanfar +2
The Galactic center offers us a unique opportunity to test General Relativity (GR) with the orbits of stars around a supermassive black hole. Observations of these stars have been…
The Post-Periapse Evolution of Galactic Center Source G1: The second case of a resolved tidal interaction with a supermassive black hole
Gunther Witzel, Breann. N. Sitarski, Andrea M. Ghez +13
We present new Adaptive Optics (AO) imaging and spectroscopic measurements of Galactic Center source G1 from W. M. Keck Observatory. Our goal is to understand its nature and relati…
Constraints on Lorentz symmetry violations with Lunar Laser Ranging
Adrien Bourgoin, Aurélien Hees, Christophe Le Poncin-Lafitte +3
We present new constraints on Lorentz symmetry (LS) violations with lunar laser ranging (LLR). Those constraints are derived in the standard-model extension (SME) framework aiming…
Testing the gravitational theory with short-period stars around our Galactic Center
A. Hees, A. M. Ghez, T. Do +19
Motion of short-period stars orbiting the supermassive black hole in our Galactic Center has been monitored for more than 20 years. These observations are currently offering a new…
Testing General Relativity with stellar orbits around the supermassive black hole in our Galactic center
A. Hees, T. Do, A. M. Ghez +14
In this Letter, we demonstrate that short-period stars orbiting around the supermassive black hole in our Galactic Center can successfully be used to probe the gravitational theory…
Universality of free fall versus ephemeris
Olivier Minazzoli, Léo Bernus, Agnès Fienga +3
When a light scalar field with gravitational strength interacts with matter, the weak equivalence principle is in general violated, leading for instance to a violation of the unive…
