The Discovery of the Massive Black Hole in the Center of the Galaxy. Outreach colloquium on the occasion of The Nobel Prize in Physics 2020

Outreach colloquium on the discovery of a supermassive compact object at the centre of our galaxy.

Black Holes are among the most mysterious objects in the Universe. They are so massive and compact that nothing - not even light - can escape their gravity. The 2020 Nobel Prize in Physics was awarded to Roger Penrose for showing that these exotic objects are a direct consequence of Einstein's general theory of relativity, and to Reinhard Genzel and Andrea Ghez for the discovery of such a monster in the center of our Galaxy. Our presentation will portrait the 40 year journey from the first indications to the overwhelming observational evidence for a extremely heavy and compact object in the Galactic Center, for which a supermassive black hole is the only known explanation. Using the world's largest telescopes and most advanced optics technology, astronomers can now follow the stars orbiting the central object, precisely measure its mass, and detect the stunning effects of general relativity. In our talk we will present both the spectacular observations and the technology behind.
