Reinhard Genzel

Reinhard Genzel ForMemRS[1] (German: [ˈʁaɪ̯nhaʁt ˈɡɛntsl̩]; born 24 March 1952) is a German astrophysicist, co-director of the Max Planck Institute for Extraterrestrial Physics, a professor at LMU and an emeritus professor at the University of California, Berkeley. He was awarded the 2020 Nobel Prize in Physics "for the discovery of a supermassive compact object at the centre of our galaxy", which he shared with Andrea Ghez and Roger Penrose.[2][3]

Life and careerEdit

Genzel was born in Bad Homburg vor der Höhe, Germany, the son of Eva-Maria Genzel and Ludwig Genzel, professor for solid state physics (1922–2003). He studied physics at the University of Freiburg and the University of Bonn where he did his PhD in 1978[4] and, in the same year, his PhD thesis on radioastronomy at the Max Planck Institute for Radio Astronomy.[4] He then worked at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. He was a Miller Fellow from 1980 until 1982, and also Associate and finally Full Professor in the Department of Physics at the University of California, Berkeley from 1981. In 1986, he left Berkeley to become a director at the Max Planck Institute for Extraterrestrial Physics in Garching and Scientific Member of the Max-Planck-Gesellschaft.[5] He also lectured at Ludwig-Maximilians-Universität München, where he has been Honorary Professor since 1988.[4] From 1999, he also had a part-time joint appointment as Full Professor at the University of California, Berkeley.[4][5] Additional activities include sitting on the selection committee for the Shaw Prize in astronomy.[6]

WorkEdit

Reinhard Genzel studies infrared- and submillimetre astronomy. He and his group are active in developing ground- and space-based instruments for astronomy. They used these to track the motions of stars at the centre of the Milky Way, around Sagittarius A*, and show that they were orbiting a very massive object, now known to be a black hole.[7] Genzel is also active in studies of the formation and evolution of galaxies.[5]

In July 2018, Reinhard Genzel et al. reported that star S2 orbiting Sgr A* had been recorded at 7,650 km/s or 2.55% the speed of light leading up to the pericentre approach in May 2018 at about 120 AU ≈ 1400 Schwarzschild radii from Sgr A*. This allowed them to test the redshift predicted by general relativity at relativistic velocities, finding additional confirmation of the theory.[8][9]
