Margaret Geller

Margaret Joan Geller (born in 1948) is an American astronomer and professor. She is a Senior Astronomer at the Smithsonian Astrophysical Observatory, and has written numerous articles and produced several award-winning scientific short films.

Her education includes a B..A. from the University of California, Berkeley in 1970, a M.A. from Princeton University in 1972, and a Ph.D. from Princeton University in 1974.

She is interested in mapping the distribution of the mysterious, ubiquitous dark matter in the universe, the halo of our own galaxy, the Milky Way, to understand the link between the history of our Galaxy and the history of the universe, mapping clusters of galaxies to understand how these systems develop over the history of the universe, and measuring and interpreting the signatures of star formation in the spectra of galaxies to understand the links between the star formation in galaxies and their environment. She leads a program called SHELS.

In 1989, together with John Huchra, she discovered the Great Wall, basing on redshift survey data from the CfA Redshift Survey.[1]
