CENTRA researchers António Amorim, Paulo Garcia and Vítor Cardoso participated in the first measurement of the Schwarzschild precession around a supermassive black hole. This was achieved with the GRAVITY instrument at the European Southern Observatory (ESO), and sets an unprecedented test of General Relativity.
