Galaxies in Collision
Talk by Rob Knop
Stars within a galaxy like our own almost never collide with each other. Galaxies themselves, however, run into each other all the time. What's more, when the Universe was younger and smaller, they ran into each other more often. In this talk, I'll give an overview of the sorts of things we see observationally when galaxies run into each other, causing not only the beautiful cosmic collisions that we've seen images of, but also triggering huge bursts of star formation and even tremendous activity at the nucleus of those galaxies.
