Reminder: Shapley Visiting Astronomer Lecture

The Dark Side of the Universe: Black Holes and Dark Matter

Saturday April 28th, 7pm, Peabody Auditorium

Presented by Dr. Christine Jones, Smithsonian Astrophysical Observatory, Harvard University

In massive galaxies and clusters of galaxies, the stars and gas make up only a small fraction of the total mass.  Most of the mass in massive galaxies and clusters is dark matter.  In this talk, Dr. Jones will describe how we use optical and X-ray observations of galaxies and clusters to trace how the dark matter is distributed and to measure the enormous amounts of energy produced by supermassive black holes that reside in the centers of galaxies.
