About the course
The DPhil in Astrophysics is a research-based degree offered by the astrophysics and theoretical physics sub-departments of Physics, available to students interested in carrying out research in observational or theoretical astrophysics, or in astronomical instrumentation. The course has a strong track record of preparing students for careers in academia and elsewhere.
The DPhil is a research-based course that normally takes three to four years of study. You will be expected to carry out your own research in areas drawn from the sub-department's exceptionally broad range of research, exploiting access to high performance computing and to the full range of space and ground-based facilities where necessary.
You should closely consult the the sub-department's areas of research interest and the list of available projects. Particular strengths include the study of cosmology, galaxies and black holes, stars and exoplanets, and include instrumentation and large telescope projects.
You will be a member of a lively research environment, and the department places great emphasis on matching student and supervisor so that work on the main research project can begin as soon as possible. A taught graduate course in the first year runs in parallel to this work, providing a comprehensive overview of both the state of modern astrophysics and the necessary skills required to make progress in 21st century research. Students are also expected to attend a suitable short course from the MPhys or other courses. Neither part of this graduate program is examined.
The lively programme of seminars, colloquia and discussion meetings held in the department ensures that you remain in touch with the cutting edge of the subject and provide an opportunity to interact with staff and with the large number of visitors who pass through the department each year. They also provide plenty of opportunity for you to gain experience in presenting your science, a critical part of a modern researcher's life.
For this course, the allocation of graduate supervision is the responsibility of the Department of Physics and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff.
Your DPhil offer is based on working with a named supervisor(s). Your supervisor(s) will be your main source of information and advice throughout the course of your research. Their responsibilities include giving you early advice about the nature of research and the standard expected, and about planning the framework of your research programme. It is likely that you will also be working closely with other members of that supervisor’s group, and sometimes collaborators from other institutes (some of you may even be jointly supervised by an academic from another institute). There may be an option to add a co-supervisor if you find yourself working closely with another group member. Under exceptional circumstances, a supervisor may be found outside the Department of Physics.
All students will be initially admitted to the status of Probationer Research Student (PRS). Within a maximum of six terms as a PRS student (and normally by the fourth term) you will be expected to apply for transfer of status from Probationer Research Student to DPhil status.
A successful transfer of status from PRS to DPhil status will require satisfactory attendance at our compulsory graduate lecture programme. You will also be required to write a report (no more than 5000 words) on your progress during the first year and you will be assessed by two members of staff (neither of whom will be your primary supervisor) . Students who are successful at transfer will also be expected to apply for and gain confirmation of DPhil status within nine terms of admission, to show that your work continues to be on track.
Both milestones normally involve an interview with two assessors (other than your supervisor) and therefore provide important experience for the final oral examination.
You will be expected to submit a thesis of no more than 250 pages (roughly 125,000 words) within four years from the date of admission. To be successfully awarded a DPhil in Astrophysics you will need to defend your thesis orally (viva voce) in front of two appointed examiners.
Over the past decade, about three quarters of graduates of the DPhil in Astrophysics have gone on to postdoctoral positions in astrophysics, and most stay the field long-term. Other graduates typically take up positions in industry, teach, or work in the financial sector or in the growing number of jobs available to those with backgrounds in 'data science'.
Changes to this course and your supervision
The University will seek to deliver this course in accordance with the description set out in this course page. However, there may be situations in which it is desirable or necessary for the University to make changes in course provision, either before or after registration. The safety of students, staff and visitors is paramount and major changes to delivery or services may have to be made in circumstances of a pandemic (including Covid-19), epidemic or local health emergency.

How to apply
You are welcome to contact either the admissions staff or academic staff who are offering research projects to discuss your application. However, such contact is not required and does not form part of the assessment of applicants.
If you are in any doubt about which physics sub-department to apply for then you are advised to contact the sub-departments concerned before applying.
The set of documents you should send with your application to this course comprises the following:
Your transcripts should give detailed information of the individual grades received in your university-level qualifications to date. You should only upload official documents issued by your institution and any transcript not in English should be accompanied by a certified translation.
More information about the transcript requirement is available in the Application Guide.
A CV/résumé is compulsory for all applications. Most applicants choose to submit a document of one to two pages highlighting their academic achievements and any relevant professional experience.
Statement of purpose/personal statement:
A maximum of 1,000 words
Your statement should focus on your interest, experience and commitment to scientific work and to astrophysics more specifically, rather than more general interests. You are not expected to invent your own research plan.
If possible, please ensure that the word count is clearly displayed on the document.
This will be assessed for:
- your interest in and experience of the subject, particularly any research experience you may have acquired in astrophysics or other fields
- evidence of understanding of the area of study including preliminary knowledge of state-of-the-art research and for candidates with more experience, details of any relevant scientific publications.
The sub-department will look for evidence of scientific reasoning and an ability to cope with new ideas and concepts, as well as an ability to work independently. The sub-department is also interested in which areas of astrophysics attract you (if known at this stage), and in understanding the reasons behind that choice.
References/letters of recommendation:
Three overall, all of which must be academic
Whilst you must register three referees, the department may start the assessment of your application if two of the three references are submitted by the course deadline and your application is otherwise complete. Please note that you may still be required to ensure your third referee supplies a reference for consideration.
Your references must all be academic.
Your references will support intellectual ability, academic achievement, motivation, and your ability to work in a group.
Applying to multiple Physics DPhil courses
If your application is related to more than one Physics DPhil course, there is no need to complete a separate application for each or pay more than one application fee. Please refer to the instructions for applying to related courses.
