The Nobel Prize in Physics 2020

Born: 16 June 1965, New York, NY, USA

Affiliation at the time of the award: University of California, Los Angeles, CA, USA

Prize share: 1/4


Since nothing, not even light, can escape black holes, they can only be observed by the radiation and the movement of nearby objects. Since the 1990s, Andrea Ghez and Reinhard Genzel with their respective research teams, have developed and refined techniques for studying the movement of stars. Observations of stars in the area around Sagittarius A* in the middle of our galaxy, the Milky Way, revealed a super massive black hole.
