Understanding Galaxies in 10^23 Easy Steps, with David Kornreich

Studying how galaxies change with time and interact with each other is made difficult by the fact that the times over which they change and interact are in the billions of years. The NSF is reluctant to fund experiments that have no hope of results for so long, so what is one to do? One solution is to use our knowledge of gravitational and hydrodynamic forces to predict what will happen when galaxies collide, or to test hypotheses of initial conditions and "postdict" the current observed universe. But these models come with their own difficulties--- how does one model the gravitational influences of over ten billion components on each other, and that's counting only the stars? Such a simulation itself might take billions of years. How do we speed up that process without sacrificing accuracy?

Public Viewing night, from 9:00 p.m. to 11:00 p.m.

You are invited to join the Ithaca College Department of Physics for a Public Viewing of the night sky at the Clinton B. Ford Observatory 9:00 p.m. to 11:00 p.m.

To attend a Public Night
Just show up at the vehicle 'turn around' in front of the entrances of Smiddy Hall and CHS (F lot side).  A shuttle van will make regular runs to convey people up to the observatory and back down. Please note that there is NO parking available up at the observatory and that the access road is NOT lighted. For your own safety, please do not walk up.

Bad Weather Plan
The "go/no-go" decision for any public night will be made at 3:30 pm on the scheduled date. Our web page and the recorded message at the observatory will be updated shortly thereafter to reflect the decision for that evening. So if you check our website or call the observatory at 607-274-3012 after 4:00 pm you will get the final decision for that evening.

The Formation and Early Evolution of Super Star Clusters: The Biggest Star Formation Events in the Universe with David Whelan, ('05), University of Virginia

It is an interesting observational fact that most stars form in clusters of stars. This would seem to contradict common sense: anyone can look up on a clear night and see stars scattered across the sky in no discernible pattern. So we are left to determine how clusters, from which stars like our Sun formed, disintegrated. Observations of nearby galaxies, particularly those that are disturbed by encounters with other galaxies, show that at times of intense starburst, a galaxy can be populated with thousands of large clusters of stars. Yet galaxies that show evidence of past disruption are curiously absent of these clusters. What are these young clusters? Why do they seem to disappear after a time? To learn more about how stars form in clusters, I concentrate on the earliest stages of formation of what are called super star clusters (SSCs). These objects are the million-star monstrosities that we see in nearby disrupted galaxies. With the help of sophisticated numerical tools, I predict what these objects look like within the first few million years of their birth, and I suggest possible reasons why they eventually fall apart and disperse their stars throughout their host galaxy.
