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 received a Bachelor of Arts degree in Physics at the University of California, Berkeley (1970) and a Ph.D. in Physics from Princeton (1975). 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 six honorary degrees (D. S. H. C.).
Geller is known for observational and theoretical work in cosmology and extragalactic astronomy. In the 1980s, she made pioneering maps of the large-scale structure of the universe, which led to the discovery of the Great Wall. With the 6.5-m MMT, she is conducting a more distant survey of the universe called HectoMAP. Geller has developed innovative techniques for investigating the internal structure and total mass of clusters of galaxies and the relationship of clusters to the large-scale structure.
