The mass distribution in the Galactic Centre from interferometric astrometry of multiple stellar orbits

GRAVITY Collaboration, R. Abuter, N. Aimar +62

The stars orbiting the compact radio source Sgr A* in the Galactic Centre are precision probes of the gravitational field around the closest massive black hole. In addition to adap…
