Margaret J. Geller, Harvard Smithsonian Center for Astrophysics will give a colloquium on the "Ultimate Mass of Galaxy Clusters" at 3:35 on Wednesday, April 22 in 150 Tate. In addition, she will deliver the 2015 Van Vleck Lecture on the topic of "Click: The 3D Universe" on Thursday, April 23, 2015 at 7:00 p.m. in 150 Tate Laboratory of Physics. The lectures are free and open to the public.

Margaret Geller received her B.A. (physics) from UC Berkeley in 1970 and her Ph.D.. from the Princeton University physics department in 1975. She joined the permanent staff of the Smithsonian Astrophysical Observatory (part of the CfA) in 1983. Geller is best know for her pioneering maps of the distribution of galaxies in the nearby universe. Together with COBE observations of fluctuations in the microwave background, these maps profoundly changed the view of large-scale structure in the universe. Geller has also made substantial contributions to the study of galaxies and their environment. 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. She received a MacArthur Fellowship (1990), the Magellanic Premium (2008), the James Craig Watson Medal (2010), the Russell Lectureship (2010), the Lilienfeld Prize of the APS (2012), and the Schwarzschild Medal (2014) of the German Astronomical Society. She is a Library Lion of the New York Public Library (1997) and she has received six honorary degrees including one from Dartmouth College (2014).
