PhD Fellowship in Theoretical Astrophysics

PhD Project in Black Hole Binaries
Niels Bohr Institute
Faculty of SCIENCE
University of Copenhagen
The Niels Bohr Institute invites applicants for a PhD fellowship in Theoretical Astrophysics. The project is part of the research project “Black Hole Binary Mergers”, which is financed by the Independent Research Fund - Danmarks Frie Forskningsfond (DFF).

The start date is (expected to be) 1 June 2024 or as soon as possible thereafter.

The project
The detection of gravitational waves ignited one of the most exciting revolutions in modern science by opening up a new window into our Universe. We will soon have access to statistical information about the distribution of masses, eccentricities, and spins of black holes in merging binary systems. Our lack of knowledge on how black hole binaries evolve and merge is one of the biggest sources of uncertainty when connecting theoretical models with gravitational wave observations. This PhD project will address this important problem relying on sophisticated computer simulations, complemented with analytical and semi-analytical approaches.

Who are we looking for?
We are looking for candidates within the field of Theoretical and Computational Astrophysics with emphasis on astrophysical fluid dynamics and magnetohydrodynamics. It is highly desirable for the candidate to posses expertise in astrophysical fluid dynamics and programming skills in Python, C, and C++. Additionally, experience with the numerical code for astrophysical fluid dynamics and magnetohydrodynamics Athena++ will be considered a valuable asset.

Our group and research - and what do we offer?
The Theoretical Astrophysics Group is part of the Niels Bohr International Academy (NBIA) hosted by The Niels Bohr Institute Faculty of SCIENCE, University of Copenhagen. The Theoretical Astrophysics Group strives for a comprehensive approach to astrophysics. Current research areas encompass protoplanetary disks and planet formation, accretion disks surrounding compact objects, galaxy clusters, and the physics of gravitational-wave sources. All problems are tackled with a wide perspective, ranging from fundamental theoretical aspects to state-of-the-art simulations with the aim of linking theory and models with observations. The NBIA is committed to fostering the traditions of internationalism, interdisciplinarity and excellence in physics, which characterize the Niels Bohr Institute. It functions as a primary center for fundamental research including particle and astroparticle physics, astrophysics and gravity, condensed matter physics, quantum optics, and biophysics. We offer creative, open, and stimulating working conditions in a dynamic and international research environment. The group has exclusive access to some of the largest dedicated astrophysics computing resources in Scandinavia, including a general-purpose high-performance computing cluster.

The PhD programme is a three year full-time study within the framework of the regular PhD programme (5+3 scheme), if you already have an education equivalent to a relevant Danish master’s degree.

Qualifications needed for the regular programme
To be eligible for the regular PhD programme, you must have completed a degree programme, equivalent to a Danish master’s degree (180 ECTS/3 FTE BSc + 120 ECTS/2 FTE MSc) related to the subject area of the project, e.g. Physics or Astrophysics. For information of eligibility of completed programmes, see General assessments for specific countries and Assessment database.

Terms of employment in the regular programme
Employment as PhD fellow is full time and for maximum 3 years.

Employment is conditional upon your successful enrolment as a PhD student at the PhD School at the Faculty of SCIENCE, University of Copenhagen. This requires submission and acceptance of an application for the specific project formulated by the applicant.

The terms of employment and salary are in accordance to the agreement between the Ministry of Finance and The Danish Confederation of Professional Associations on Academics in the State (AC). The position is covered by the Protocol on Job Structure.

Responsibilities and tasks in both PhD programmes

• Carry through an independent research project under supervision
• Complete PhD courses corresponding to approx. 30 ECTS / ½ FTE
• Participate in active research environments in Denmark and abroad.
• Teaching and knowledge dissemination activities
• Write scientific papers aimed at high-impact journals
• Write and defend a PhD thesis on the basis of your project

We are looking for the following qualifications:

• Professional qualifications relevant to the PhD project. It is highgly desirable that the candidate posses expertise in astrophysical fluid dynamics and programming skills in Python, C, and C++.
• Relevant publications (if any)
• Relevant work experience (if any)
• Curious mind-set with a strong interest in Theoretical Astrophysics
• Excellent English skills

Application and Assessment Procedure
Your application including all attachments must be in English and submitted electronically by clicking APPLY NOW below.

Please include:

• Cover Letter, stating research interests, your motivation and background for applying for this PhD project, and (non-binding) plans for possible research projects within your PhD (max 3 pages PDF).
• Curriculum vitae including information about your education, research experience, language skills and other skills relevant for the position
• Original diplomas for Bachelor of Science or Master of Science and transcript of records in the original language, including an authorized English translation if issued in another language than English or Danish. If not completed, a certified/signed copy of a recent transcript of records or a written statement from the institution or supervisor is accepted.
• Publication list (if possible)

The further process
After deadline, a number of applicants will be selected for academic assessment by an unbiased expert assessor. You are notified, whether you will be passed for assessment.

The assessor will assess the qualifications and experience of the shortlisted applicants with respect to the above mentioned research area, techniques, skills and other requirements. The assessor will conclude whether each applicant is qualified and, if so, for which of the two models. The assessed applicants will have the opportunity to comment on their assessment.
