Margaret J. Geller (born December 8, 1947) is an American astrophysicist at the Center for Astrophysics | Harvard & Smithsonian. 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 ...
Dr. Geller's current main research interests are: Mapping the distribution of the mysterious, ubiquitous dark matter in the universe. She leads a project called SHELS. Investigating the implications of the discovery of hypervelocity stars, stars ejected a high velocity from the Galactic center.

redshift survey (Geller et al. 2005 ApJLett, 635, L125; Geller et al. 2010 ApJ, 709, 832). First combined weak lensing and redshift survey detection of the evolution of the mass associated with star-forming galaxies (Utsumi, Geller et al. 2016, ApJ, 833, 156). • Discovery of hypervelocity stars and development of their implications
She has developed and applied techniques for measuring the matter distribution in clusters of galaxies. She is currently making a deeper map of the galaxy distribution called HectoMAP. Geller is member of the National Academy of Sciences and of the American Academy of Arts and Sciences.
