Requirements may or may not be reflected identically in departmental URLs.)
Master of Arts and Doctor of Philosophy. The department also participates in the Ph.D. program in astrophysics.
Members of the Department of Astronomy use the WIYN (Wisconsin-Indiana-Yale-National Optical Astronomy Observatories) 3.5m and 0.9m telescopes at Kitt Peak National Observatory near Tucson, Arizona, to carry out research in optical astronomy. The advanced-technology 3.5m telescope delivers superb image quality over a wide field and is also 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, spacecraft, and balloon-borne detectors that are developed within the department. Several instrument development labs and machine shops support the optical and high-energy research programs.
Research in the Department of Astronomy is supported by excellent computational facilities. Students, faculty, and research staff have fast desktop machines with 1-Gbps network connectivity within the department and to the outside world. The department maintains several multi-Terabyte file servers and a number of high-performance computer platforms for simulations and data analysis. Indiana University operates BigRed, one of the fastest university-owned supercomputers in the world, as well as SMP clusters called Quarry and Libra. These computational research capabilities are supported by two massive data processing and storage systems: the Data Capacitor, which is a fast file system that can manipulate up to 0.5 Petabytes of data simultaneously, and the Massive Data Storage Service, which can permanently archive more than 4 Petabytes of data.
Special Departmental Requirements
(See also general University Graduate School requirements.)
Good preparation for graduate work in astronomy or astrophysics requires the same training in physics and mathematics needed for a bachelor’s degree in physics, plus a familiarity with the subject matter of introductory astronomy or astrophysics courses, such as A221-A222 or A451-452. An undergraduate major in astronomy, astrophysics, physics, or mathematics that has provided such a background is usually required for admission. Any necessary undergraduate courses to strengthen students’ backgrounds will not receive graduate credit.
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.
Master of Arts Degree
A minimum of 30 credit hours, including any three astronomy graduate core courses (see below).
A thesis may be required, at the discretion of the department. Students for whom the thesis requirement is waived must still complete a project that demonstrates research proficiency.
An oral examination must be passed covering general astronomy at the A451-452 level, the core courses applied toward the degree, and the thesis research.
Doctor of Philosophy Degree
A total of 90 credit hours. Students are required to take six of the following core courses: A505, A520, A 530, A540, A550, A570, A575, and A580. Normally, these courses are offered at the rate of three courses per year, and they may be taken in any sequence. The remainder of the graduate program consists of elective courses, seminars on advanced topics, research, and dissertation.
Grades below B (3.0) in core courses may be counted toward degree requirements only at the discretion of the department.
Most doctoral candidates in astronomy minor in physics or scientific computing. Other minors may be permitted at the discretion of the department.
In order to be advanced to candidacy, a student must pass a written examination covering the core course material plus general astronomy at the A451-452 level. The examination may be taken no more than twice. The examination is usually offered once a year in late May/early June. In its current form, it consists of one five-hour exam covering the material in the core courses and general astronomy knowledge at the undergraduate level.
The candidacy seminar is an oral presentation to the research committee, usually consisting of a thesis proposal and/or a summary of past research activity. It must be completed within a year of passing the written qualifying examination (typically by the start of the fourth year of residence).
Oral defense of the dissertation.
Ph.D. Minor in Astronomy
Students from other departments who wish to minor in astronomy must complete at least 9 credit hours of graduate courses in astronomy at the 500 level with an average GPA of B (3.0) or higher. The student should discuss proposed course work for the minor with an advisor from the Department of Astronomy, usually the Director of Graduate Studies. One astronomy course at the 400 level (listed below) may be substituted for one of the 500 level courses upon approval by the student’s astronomy advisor.
