Astronomy 410/510: Observational Astrophysics

Students in ASTR 410/510 conduct observational projects using the mighty 0.25-meter Great Ohio Telescope. They conceive their own projects and write observing proposals, then convene as a Time Allocation Committee (TAC) to review the proposals and schedule telescope time. Students acquire, reduce, and analyze the data for their projects, and present the results in written papers and oral presentations at a mock scientific conference.
