Dr. Andrew Benson
George Ellery Hale Distinguished Scholar in Theoretical Astrophysics, The Carnegie Observatories
Astronomy
tells us that most of our universe is made from so-called "dark matter"
-- an invisible substance that holds together galaxies and clusters of
galaxies. But how can we study something that we can't see? Dr. Benson
will describe the many ingenious ways that astronomers have found -- and
continue to find -- to understand the nature of dark matter, including
looking at how light from distant galaxies is deflected by gravitational
lensing, and searching for the smallest galaxies in the universe.
