Detection of the Schwarzschild precession in the orbit of the star S2 near the Galactic centre massive black hole
The star S2 orbiting the compact radio source Sgr A* is a precision probe of the gravitational field around the closest massive black hole (candidate). Over the last 2.7 decades we have monitored the starās radial velocity and motion on the sky, mainly with the SINFONI and NACO adaptive optics ā¦
