The Astronomy Department's graduate program emphasizes research at the frontiers of astrophysics. Areas of concentration are theoretical, observational, and instrumentational astronomy.
The Graduate Program of the University of Arizona Department of Astronomy and Steward Observatory trains students to become independent scientists with the knowledge and skills to conduct and communicate world-class astronomical research. A Ph.D. in Astronomy and Astrophysics from the University of Arizona signifies a student’s excellence in research, which is demonstrated through a significant, original, and scholarly contribution to astrophysical knowledge. We admit graduate students who have met high standards of achievement and shown potential for conducting original research, with the expectation that they will succeed in attaining a doctoral degree in astronomy and astrophysics. The academic program is structured in support of this goal, emphasizing research throughout the graduate career; providing mentoring from individual advisors and our interactive community of students, postdocs, scientists, and faculty. Students will gain firsthand experience with the tools and facilities that define the state of the art in our field.

By the end of the third semester, the student should have completed the core Ph.D. qualification requirement, which consists of seven graduate astronomy core courses, with a grade of C or better in each course. The student's overall GPA must remain 3.0 or above to hold either a research or teaching assistantship. A GPA of 3.0 is also a graduation requirement for either a Masters or Ph.D. in Astronomy.
Core courses will always be taken for letter grades by Astronomy students, but may be taken for Pass/Fail credit, with instructor approval, by students from other departments. Electives and seminars may be taken for Pass/Fail credit, subject to the limitation of no more than two Pass/Fail courses per semester and the overall constraint of having taken a sufficient number of credits in letter-graded courses.
The astronomy department allows graduate students whose Ph.D. major is in another department to minor in astronomy. We require that they pass nine units of coursework that the department considers acceptable for this purpose, preferably "core" courses, and that one astronomy faculty member participate in the preliminary and final oral exams.
See the Graduate Catalogue and the "Handbook for Completing the Steps to Your Degree" for more information. These publications also contain requirements involving the dissertation, as does also the Manual for Theses and Dissertations.
