Andrea Mia Ghez (born June 16, 1965) is an American

astrophysicist, Nobel laureate, and professor in the Department of Physics and Astronomy and the Lauren B. Leichtman & Arthur E. Levine chair in Astrophysics, at the University of California, Los Angeles.[1] Her research focuses on the center of the Milky Way galaxy.[2]

In 2020, she became the fourth woman to be awarded the Nobel Prize in Physics, sharing one half of the prize with Reinhard Genzel (the other half being awarded to Roger Penrose).[1][3] The Nobel Prize was awarded to Ghez and Genzel for their discovery of a supermassive compact object, now generally recognized to be a black hole, in the Milky Way's Galactic Center.[4][5]

Early life

Ghez was born in

Irish Catholic family from North Attleborough, Massachusetts.[10]

Her family moved from New York to Chicago when she was a child, and Ghez attended the

University of Chicago Lab School.[6][11] The Apollo program Moon landings inspired Ghez to aspire to be the first female astronaut, and her mother encouraged that goal by purchasing a telescope.[12][13] Her most influential female role model was her high school chemistry teacher.[14]

She began college by majoring in mathematics, then changed to physics.

PhD under the direction of Gerry Neugebauer at the California Institute of Technology in 1992.[19]

Career

Ghez's research employs high spatial resolution imaging techniques, such as the

Keck telescopes,[20] to study star-forming regions and the supermassive black hole at the center of the Milky Way known as Sagittarius A*.[21] She uses the kinematics of stars near the center of the Milky Way as a probe to investigate this region.[22] The high resolution of the Keck telescopes[23] gave a significant improvement over the first major study of galactic center kinematics by Reinhard Genzel's group.[24]

In 2004, Ghez was elected to the

National Academy of Sciences, and in 2012, she was elected to the American Philosophical Society.[25][26] In 2019, she was elected as a Fellow of the American Physical Society (APS).[27]

Ghez has appeared in many television documentaries produced by networks such as the

Nova.[28] She was identified as a Science Hero by The My Hero Project.[12] In 2000, Discover magazine listed Ghez as one of 20 promising young American scientists in their respective fields.[2]

Black hole at the Galactic Center (Sgr A*)

Main article: Sagittarius A*

By imaging the

S0-102, was identified by her team at UCLA, orbiting the Galactic Center.[29] Using Kepler's third law, Ghez's team used the orbital motion to show that the mass of Sgr A* is 4.1±0.6 million solar masses.[30] Because the Galactic Center where Sgr A* is located, is one hundred times closer than M31 where the next nearest supermassive black hole (M31*) is,[31] it is one of the best demonstrated cases for a supermassive black hole.[32][33]

In 2020, Ghez shared the Nobel Prize in Physics with Roger Penrose and Reinhard Genzel, for their discoveries relating to black holes.[4] Ghez and Genzel were awarded one half of the prize for their discovery that a supermassive black hole most likely governs the orbits of stars at the center of the Milky Way.[34] Ghez was the fourth woman to win the physics Nobel since its inception, being preceded by Marie Curie (1903), Maria Goeppert Mayer (1963), and Donna Strickland (2018).[3]
