Members of the Department of Astronomy use the WIYN (Wisconsin-Indiana-Yale-National Optical Astronomy Observatories) 3.5m telescope at Kitt Peak National Observatory near Tucson, Arizona, to carry out research in optical astronomy. This advanced-technology telescope is optimized for multiobject spectroscopy, including a high-spectral-resolution mode and high-spatial-resolution imaging. Indiana University holds a 17 percent share of the WIYN facility. Two fully robotic telescopes are located in the Morgan-Monroe State Forest 16 miles from campus. These are a 0.4m telescope that is used for automated CCD photometry and a new 1.25m telescope to be used for automated spectroscopy. A remote observing center in the department is equipped for communication with both the WIYN and local telescopes. The High-Energy Astrophysics Group carries out research with underground and balloon-borne particle detectors that are developed within the department. Several instrument development labs and a machine shop support the optical and high-energy research programs.
Research in the Department of Astronomy is supported by excellent computer facilities at Indiana University. These include powerful workstations and servers within the astronomy department, an IBM RS/6000 SP distributed-memory parallel supercomputer, a computer automated virtual environment (CAVE), and a high-performance mass storage facility.

All graduate applicants must submit Graduate Record Examination scores on both the General Test and the Subject Test in physics. Scores should be sent directly to the department, not to the University Graduate School.
The 400-level courses listed here and described in the College of Arts and Sciences bulletin are open to graduate students at the discretion of the department.
