Geoffrey William Marcy (born

September 29, 1954) is an American astronomer. He is one of the pioneers and leaders in the

discovery and characterization of exoplanets. Marcy was Professor of Astronomy at the University of California,

Berkeley and an Adjunct Professor of Physics and Astronomy

at San Francisco State

University before stepping down in October 2015. His colleagues

in the Berkeley Astronomy Department forced him to resign after allegations of

sexual harassment. Marcy and his research

teams are recognized for discovering many extrasolar planets, including 70 out of the first 100

known exoplanets and also the first planetary system around a

Sun-like star, Upsilon Andromedae. Marcy

was a co-Investigator on the NASA Kepler missionthat discovered over 4000 exoplanets. Early

collaborators include R. Paul Butler, Debra Fischer and Steven S. Vogt. Later collaborators include Jason Wright,

Andrew Howard, Katie Peek, John Johnson, Erik Petigura, Lauren Weiss, Lea

Hirsch and the Kepler Science Team. Marcy graduated from Granada Hills High School in

Granada Hills, California, in 1972. He graduated with a Bachelor of Arts summa cum laude with a double major in physics and astronomy from the University

of California, Los Angeles in 1976. He then completed a

doctorate in astronomy in 1982 at the University

of California, Santa Cruz,[ with much of his work done at Lick Observatory. Marcy has held teaching and research

positions, first at the Carnegie Institution of

Washington (then the Mt. Wilson and Las Campanas Observatories)

as a Carnegie Fellow from 1982 to 1984. He then worked as an Associate

Professor of Physics and Astronomy from 1984 to 1996 and then as a

Distinguished University Professor from 1997 to 1999 at the San Francisco State

University. Marcy was a Professor of Astronomy and the Watson and

Marilyn Alberts Chair for SETI at the University of California, Berkeley from

1999 through 2015. In 2015, he resigned after being found in violation of UC

Berkeley's sexual harassment policy. From 2000 to 2012, he was the Director of

UC Berkeley's Center for Integrative Planetary Science. Marcy was also one of

the project leaders of the Breakthrough Initiatives that

will search for intelligent life in the universe, using large radio and optical

telescopes. Marcy and his team confirmed Michel Mayor and Didier

Queloz's discovery of the first extrasolar planet orbiting a

Sun-like star—51 Pegasi b. Two

months later, Marcy and his team followed this confirmation with the

announcement of the discovery of two additional planets around 47 Ursa Majoris and

70 Virginis. Other achievements include discovering the first multiple

planet system around a star similar to our own (Upsilon around

another star, simultaneously with David Charbonneau and Timothy Brown (HD209458b), the first extrasolar planet orbiting beyond

5 AU (55 Cancri d), and the first Neptune-sized planets (Gliese 436b and 55 Cancri e). Marcy was a Co-Investigator of the NASA Kepler

mission[10] that discovered over 4000

exoplanets, most being smaller than 4 times the size of Earth. His team, led by

Erik Petigura and Andrew Howard, showed that approximately 20% of Sun-like

stars have a planet of 1–2 times the size of Earth and receive incident stellar

light within a factor of 4 of the light the Earth receives from the Sun, making

them warm planets, many of which accommodate liquid water.

More

recently, in May 2017, Marcy was involved in studies related to laser light

emissions from stars, as a way of detecting technology-related

signals from an alien civilization.

The study included Tabby's Star (KIC

8462852), an oddly dimming star in which its unusual starlight fluctuations may

be the result of interference by an artificial megastructure, such as a Dyson swarm, made by such

a civilization. No evidence was found for technology-related signals from

Tabby's Star in the studies.
