DPhil in Astrophysics
About the course
The DPhil in Astrophysics is a research-based degree available to students interested in carrying out research in observational or theoretical astrophysics, or in astronomical instrumentation.
This research-based course normally takes three to four years of study and has a strong track record of preparing students for careers in academia and elsewhere. You will be a member of a lively research environment and the department places great emphasis on matching student and supervisor.
You will be expected to carry out your own research project, which will be offered from the Sub-department of Astrophysics’ broad range of research areas. These include:
- cosmology;
- exoplanets and stellar physics;
- galaxies;
- instrumentation;
- theory; and
- transients, pulsars and high-energy astrophysics.
Your research work begins on day one and will be underpinned by a taught graduate course in the first year that runs in parallel. It will provide a comprehensive overview of both the state of modern astrophysics and the necessary skills required to make progress in 21st century research. You will also have the opportunity to follow courses taught at other departments across the Maths, Physics and Life Sciences division.
You will engage in a thorough skills training programme which includes a range of workshops and seminars in transferable skills, generic research skills and specific research techniques. There are also numerous seminars and lectures held in the department by local and visiting physicists, and you will be provided with many opportunities to meet experts in various fields. There will also be opportunity for you to present your work at both formal and informal conferences, seminars and colloquia.
Attendance
The course is full-time and requires attendance in Oxford. Full-time students are subject to the University's Residence requirements.
During your DPhil, you will be expected (and supported) to travel, both to meet and work with collaborators and to carry out fieldwork where appropriate, through trips to observatories and on-site experimental work.
Provision exists for students on some courses to undertake their research in a ‘well-founded laboratory’ outside of the University. This may require travel to and attendance at a site that is not located in Oxford. Where known, existing collaborations will be outlined on this page. Please read the course information carefully, including the additional information about course fees and costs.
Resources to support your study
As a graduate student, you will have access to the University's wide range of world-class resources including libraries, museums, galleries, digital resources and IT services.
The Bodleian Libraries is the largest library system in the UK. It includes the main Bodleian Library and libraries across Oxford, including major research libraries and faculty, department and institute libraries. Together, the Libraries hold more than 13 million printed items, provide access to e-journals, and contain outstanding special collections including rare books and manuscripts, classical papyri, maps, music, art and printed ephemera.
The University's IT Services is available to all students to support with core university IT systems and tools, as well as many other services and facilities. IT Services also offers a range of IT learning courses for students, to support with learning and research.
You will have access to appropriate computing equipment and support, which will be discussed with you before your arrival. This may include access to high performance computing and to the full range of space and ground-based facilities where necessary. Additionally, if you are working on a computationally intensive project, you will have appropriate access to the departmental cluster computers and national facilities.
You will be provided with a desk in a shared office space in the Denys Wilkinson Building - or, if appropriate, with the theory sub-department - alongside astrophysics staff, with whom you will share a variety of meeting rooms and an on-site canteen which doubles as a social space for the group.
Supervision
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), who you will have the opportunity to meet individually with to discuss your project. 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.
Assessment
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 the compulsory graduate lecture programme. You will also be required to write a report 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.
Graduate destinations
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 if a pandemic, epidemic or local health emergency occurs. In addition, in certain circumstances, for example due to visa difficulties or because the health needs of students cannot be met, it may be necessary to make adjustments to course requirements for international study.
Where possible your academic supervisor will not change for the duration of your course. However, it may be necessary to assign a new academic supervisor during the course of study or before registration for reasons which might include illness, sabbatical leave, parental leave or change in employment.
For further information please see our page on changes to courses and the provisions of the student contract regarding changes to courses.

Graduate students also get to benefit from the close relations the department foster’s with other facilities in the UK and around the world. In the UK, these include the leading science and innovation campus at Harwell home to the Rutherford Appleton Laboratory and Diamond Light Source synchrotron among others. Internationally, it extends to the Large Hadron Collider at CERN, T2K in Japan, DUNE in the USA and large telescopes around the world.
Each year, the department welcomes approximately 90 graduate research students to study for a 3 to 4-year DPhil research degree – which is equivalent to a PhD. A taught masters’ degree course is offered joined by the department and the Mathematical Institute and welcomes approximately 50 students annually.
The department’s research students have access to world-class facilities and resources, from the ultra-low vibration and ultra-low temperature labs in the state-of-the-art Beecroft Building, to the in-house specialist research facilities, mechanical and electronic workshops and technicians.
Research students can choose from a range of specialisms across the six sub-departments of astrophysics; atmospheric, oceanic and planetary physics; atomic and laser physics; condensed matter physics; particle physics; and theoretical physics. Each of these sub-departments is autonomous, although many of the research projects available are interdisciplinary.
Funding
For entry in the 2025-26 academic year, the collegiate University expects to offer over 1,000 full or partial graduate scholarships across a wide range of graduate courses.
If you apply by the January deadline shown on this page and receive a course offer, your application will then be considered for Oxford scholarships. For the majority of Oxford scholarships, your application will automatically be assessed against the eligibility criteria, without needing to make a separate application. There are further Oxford scholarships available which have additional eligibility criteria and where you are required to submit a separate application. Most scholarships are awarded on the basis of academic merit and/or potential.
To ensure that you are considered for Oxford scholarships that require a separate application, for which you may be eligible, use our fees, funding and scholarship search tool to identify these opportunities and find out how to apply. Alongside Oxford scholarships, you should also consider other opportunities for which you may be eligible including a range of external funding, loan schemes for postgraduate study and any other scholarships which may also still be available after the January deadline as listed on our fees, funding and scholarship search tool.
Details of college-specific funding opportunities can also be found on individual college websites:
Please refer to the College preference section of this page to identify which of the colleges listed above accept students for this course.
For the majority of college scholarships, it doesn’t matter which college, if any, you state a preference for in your application. If another college is able to offer you a scholarship, your application can be moved to that college if you accept the scholarship. Some college scholarships may require you to state a preference for that college when you apply, so check the eligibility requirements carefully.

Following the period of fee liability, you may also be required to pay a University continuation charge and a college continuation charge. The University and college continuation charges are shown on the Continuation charges page.
Where can I find further information about fees?
The Fees and Funding section of this website provides further information about course fees, including information about fee status and eligibility and your length of fee liability.
Additional information
There are no compulsory elements of this course that entail additional costs beyond fees (or, after fee liability ends, continuation charges) and living costs. However, please note that, depending on your choice of research topic and the research required to complete it, you may incur additional expenses, such as travel expenses, research expenses, and field trips. You will need to meet these additional costs, although you may be able to apply for small grants from your department and/or college to help you cover some of these expenses.
Living costs
In addition to your course fees and any additional course-specific costs, you will need to ensure that you have adequate funds to support your living costs for the duration of your course.
Living costs for full-time study
For the 2025-26 academic year, the range of likely living costs for a single, full-time student is between £1,425 and £2,035 for each month spent in Oxford. We provide the cost per month so you can multiply up by the number of months you expect to live in Oxford. Depending on your circumstances, you may also need to budget for the costs of a student visa and immigration health surcharge and/or living costs for family members or other dependants that you plan to bring with you to Oxford (assuming that dependant visa eligibility criteria are met).
Further information about living costs
The current economic climate and high national rate of inflation make it very hard to estimate potential changes to the cost of living over the next few years. For study in Oxford beyond the 2025-26 academic year, it is suggested that you budget for potential increases in living expenses of around 4% each year – although this rate may vary depending on the national economic situation. For further information, please consult our more detailed information about living costs, which includes a breakdown of likely living costs in Oxford for items such as food, accommodation and study costs.
