Margaret
J. Geller
 (born December 8,
1947) is an American astrophysicist at the Harvard–Smithsonian
Center for Astrophysics
. Her work has included pioneering maps of
the nearby universe, studies of the relationship between galaxies and their
environment, and the development and application of methods for measuring the
distribution of matter in the universe. Geller made pioneering maps of
large-scale structure in the universe. Geller received a Bachelor of Arts degree in Physics at the University of California,
Berkeley
 (1970) and a Ph.D. in Physics from Princeton (1974).
Geller completed her doctoral dissertation, titled “Bright galaxies in
rich clusters: a statistical model for magnitude distributions”, under the
supervision of James Peebles Although Geller was
thinking about studying solid state physics in graduate school, Charles Kittel suggested she go to Princeton to study
astrophysics.
After research fellowships at the Harvard–Smithsonian Center for Astrophysics and the
Institute of Astronomy in Cambridge, England, she became an assistant professor
of Astronomy at Harvard University (1980-1983).
She then joined the permanent scientific staff of the Smithsonian
Astrophysical Observatory
, a partner in the Harvard-Smithsonian
Center for Astrophysics
. Geller is a Fellow of the American
Association for the Advancement of Science and a Fellow of the American Physical
Society. In 1990, she was elected as a Fellow of the American Academy of Arts
and Sciences. Two years later, she was elected to the Physics section of
the US National Academy of Sciences.
From 2000 to 2003, she served on the Council of the National Academy of
Sciences. She has received seven honorary degrees (D. S. H. C. or L. H. C.). Geller
is known for observational and theoretical work in cosmology and extragalactic astronomy.
Her long range goals are to discover what the universe looks like and to
understand how the patterns we observe today evolved. In the 1980s, she made
pioneering maps of the nearby universe, which included the Great Wall[8] and was the inspiration for Jasper Johns 2020 piece called Slice. Her
SHELS project maps the distribution of dark matter in the universe. With the
6.5-m MMT, she leads a deeper
survey of the middle-aged universe called HectoMAP. Geller has developed
innovative techniques for investigating the structure and mass of clusters of galaxies and
the relationship between clusters and their surroundings. Geller is also a
co-discoverer of hypervelocity stars which
may be an important tracer of the matter distribution in the Galaxy.
