Andrea Ghez, US astrophysicist, illustration
Illustration of the US astrophysicist Andrea Ghez (born 1965). Ghez is best known for her work studying the centre of our galaxy, the Milky Way. Ghez used infrared observations from the Keck Observatory on Maunakea on Hawai'i, to study the stars at the centre of our galaxy. By following the orbits of stars around the centre of the galaxy she was able to calculate the mass of the object at its centre, determining that it was a supermassive compact object, which is now widely accepted to be a supermassive black hole. Ghez shared the 2020 Nobel Prize in physics with Roger Penrose and Reinhard Genzel for this work.
