Georgia State University at Georgia State is split between physics and astronomy. Areas of research range from biophysics, condensed matter physics, neurophysics, nuclear physics, and physics education and innovative instruction. The astronomy program uses many observatories, including the Lowell Observatory in Flagstaff, Arizona and the Small and Moderate Aperture Research Telescope System (or SMARTS) in Chile, and the CHARA array on Mount Wilson Observatory in Los Angeles County, California, Hard Labor Creek Observatory in Rutledge, Georgia, and the Urban Life Observatory, all of which are operated by Georgia State. Astronomy is now also a partner in the Apache Point Observatory 3.5-m telescope. Biological
United States Naval Observatory Flagstaff Station astronomical interferometer of the venerable and proven Michelson Interferometer design. As noted, the majority of interferometric science and operations are funded and managed by NOFS; however, Lowell Observatory and NRL join in the scientific efforts through their fractions of time to use the interferometer; 85% Navy (NOFS and NRL); and 15% Lowell. NPOI is one of the few major instruments globally which can conduct "optical" interferometry. See an illustration of its layout, at bottom. NOFS has used NPOI to conduct a wide and diverse series of scientific studies, beyond just the study of absolute astrometric positions of stars. Additional NOFS
