About the Program

The Department of Astronomy offers a graduate program aimed at the PhD degree in astrophysics. Entering students need not have majored in astronomy, although some background in astronomy is desirable. A strong background in physics, however, is essential.

Research is a major part of the PhD program, and the department offers opportunities in a wide variety of fields, including theoretical and observational astrophysics; infrared, optical, and radio astronomy; galactic structure and dynamics of stellar systems; high-energy astrophysics and cosmology; and star and planet formation.

The department has established six years as the normative time to degree. Normative time is the elapsed calendar time in years that under normal circumstances will be needed to complete all requirements for the PhD, assuming a student who enters without deficiencies, who is engaged in full-time uninterrupted study, and who is making desirable progress toward the degree.

Admissions

Admission to the University

Minimum Requirements for Admission

The following minimum requirements apply to all graduate programs and will be verified by the Graduate Division:

  1. A bachelor’s degree or recognized equivalent from an accredited institution;
  2. A grade point average of B or better (3.0);
  3. If the applicant comes from a country or political entity (e.g., Quebec) where English is not the official language, adequate proficiency in English to do graduate work, as evidenced by a TOEFL score of at least 90 on the iBT test, 570 on the paper-and-pencil test, or an IELTS Band score of at least 7 on a 9-point scale (note that individual programs may set higher levels for any of these); and
  4. Sufficient undergraduate training to do graduate work in the given field.

Applicants Who Already Hold a Graduate Degree

The Graduate Council views academic degrees not as vocational training certificates, but as evidence of broad training in research methods, independent study, and articulation of learning. Therefore, applicants who already have academic graduate degrees should be able to pursue new subject matter at an advanced level without need to enroll in a related or similar graduate program.

Programs may consider students for an additional academic master’s or professional master’s degree only if the additional degree is in a distinctly different field.

Applicants admitted to a doctoral program that requires a master’s degree to be earned at Berkeley as a prerequisite (even though the applicant already has a master’s degree from another institution in the same or a closely allied field of study) will be permitted to undertake the second master’s degree, despite the overlap in field.

The Graduate Division will admit students for a second doctoral degree only if they meet the following guidelines:

  1. Applicants with doctoral degrees may be admitted for an additional doctoral degree only if that degree program is in a general area of knowledge distinctly different from the field in which they earned their original degree. For example, a physics PhD could be admitted to a doctoral degree program in music or history; however, a student with a doctoral degree in mathematics would not be permitted to add a PhD in statistics.
  2. Applicants who hold the PhD degree may be admitted to a professional doctorate or professional master’s degree program if there is no duplication of training involved.

Applicants may apply only to one single degree program or one concurrent degree program per admission cycle.

Required Documents for Applications

  1. Transcripts: Applicants may upload unofficial transcripts with your application for the departmental initial review. If the applicant is admitted, then official transcripts of all college-level work will be required. Official transcripts must be in sealed envelopes as issued by the school(s) attended. If you have attended Berkeley, upload your unofficial transcript with your application for the departmental initial review. If you are admitted, an official transcript with evidence of degree conferral will not be required.
  2. Letters of recommendation: Applicants may request online letters of recommendation through the online application system. Hard copies of recommendation letters must be sent directly to the program, not the Graduate Division.
  3. Evidence of English language proficiency: All applicants from countries or political entities in which the official language is not English are required to submit official evidence of English language proficiency. This applies to applicants from Bangladesh, Burma, Nepal, India, Pakistan, Latin America, the Middle East, the People’s Republic of China, Taiwan, Japan, Korea, Southeast Asia, most European countries, and Quebec (Canada). However, applicants who, at the time of application, have already completed at least one year of full-time academic course work with grades of B or better at a US university may submit an official transcript from the US university to fulfill this requirement. The following courses will not fulfill this requirement:
    • courses in English as a Second Language,
    • courses conducted in a language other than English,
    • courses that will be completed after the application is submitted, and
    • courses of a non-academic nature.

If applicants have previously been denied admission to Berkeley on the basis of their English language proficiency, they must submit new test scores that meet the current minimum from one of the standardized tests. Official TOEFL score reports must be sent directly from Educational Test Services (ETS). The institution code for Berkeley is 4833. Official IELTS score reports must be mailed directly to our office from British Council. TOEFL and IELTS score reports are only valid for two years.

Admission to the Program

In addition to the application, transcripts of undergraduate work, and letters of recommendation, applicants must submit scores of the General and Physics Graduate Record Examinations (GRE), and, if applicable, the Test of English as a Foreign Language (TOEFL).

Detailed information concerning admission, financial aid, and degree requirements may be found on the department's website.

The Introduction to Current Research seminar is required of all students in their first year. This consists of weekly lectures by different faculty members and research staff, and introduces the student to current research being carried out in the department and nearby labs. (This course is not a preliminary exam topic.)

*

 These courses are offered based on interest.

Teaching

All candidates for the Ph.D. in Astrophysics must acquire two semesters of teaching experience during their graduate career, whether or not compensated.

It is desirable that this requirement be satisfied early in the graduate career, but it may be delayed for those international students who have not acquired adequate command of English, or other reasons, at the discretion of the Chairperson. The requirement may be waived for transfer students who have acquired similar teaching experience elsewhere.

Examinations

All candidates must pass two oral examinations administered by the faculty. The preliminary examination should be completed by the end of the second academic year of study and focuses on basic competency in three subfields selected by the student. The qualifying examination should be completed by the end of the fourth academic year of study and is composed of a review of a thesis topic and an examination of a student’s competency in his or her research subfield. Students entering with a Master’s Degree or its equivalent may have the preliminary examination requirement waived subject to the discretion of the Chair.

Thesis

The thesis is an original piece of research carried out by the candidate under the supervision of a thesis adviser and two other faculty members (one of whom must be from another discipline). The Graduate Division has published guidelinesfor dissertations and theses.

University Registration

Registration is required of all students making any use of University facilities, including access to faculty. A student is required to be registered, or pay the filing fee, whichever is applicable for the semester in which the degree is conferred. To be eligible for filing fee status the student must have been continuously registered since entering (allowing for one year of approved withdrawal), and registered in the term immediately preceding the one in which the Filing Fee is requested. You must register each semester before the end of the third week of classes.

Master's Degree

Students are normally not admitted for the master’s degree only, but may find it worthwhile to add to their record en route to the PhD. Once these requirements have been fulfilled, the student should see the student affairs officer to obtain an Application for Candidacy for the master’s degree.

In order to earn the master's, students are required to pass the preliminary exam and must complete 24 units of upper division and graduate courses, including 12 units of “non-research” (lecture) courses.
