The Oberlin Chapter of Sigma Xi, a national science honor society, is proud to sponsor a lecture by our very own Jillian Scudder, assistant professor of physics.
Galaxies are not always solitary islands in a mostly-empty Universe - occasionally they find themselves with close neighbors. When the neighbors are close enough, gravity promises us a cosmic smash-up, with the two galaxies flung around each other to form a new galaxy.
This process provides some of the most photogenic images, but what can we learn from this process? Prof. Scudder will discuss how we search for these collisions between galaxies, how collisions change the galaxies involved, and what we still hope to learn.
