Job description

Position Description

The Niels Bohr International Academy (NBIA) at the Niels Bohr Institute invites expressions of interest for a fixed-term assistant professorship in theoretical and gravitational wave astrophysics. The appointment will be for four years, with the possibility of a one-year extension. The appointment is expected to begin in fall 2027, but other starting dates can be negotiated.

The assistant professor will join the Theoretical Astrophysics Group led by Martin Pessah and is expected to develop and lead research projects as part of a major expansion supported by an ERC Advanced Grant and the Carlsberg Foundation’s Semper Ardens Accomplish Grant. A main goal of the program is to bring together astrophysical fluid dynamics and gravitational wave astrophysics to understand the environments leading to compact binary mergers, from stellar-mass compact objects to supermassive black holes. A central focus is the formation, evolution, and observable signatures of black-hole binaries in turbulent, magnetized disks around supermassive black holes. Candidates with relevant expertise from other areas will receive full consideration.

We seek a researcher with a strong record of original research contributions and a clear scientific vision. The successful candidate will develop an ambitious and independent research program. We particularly welcome candidates whose complementary expertise can open new directions for the Theoretical Astrophysics Group. We envision that this position can provide a foundation for establishing an independent research group through a successful grant application to a Danish or European research agency. Assistant professors at NBIA receive mentoring and support in applying for these grants.

The assistant professor will have the opportunity to mentor students and junior researchers and will also be given freedom to co-organize international workshops and PhD schools. There is an opportunity to launch and run a new seminar program in the field. Teaching responsibilities are limited and provide opportunities to engage with students. The assistant professor will have access to travel funding and the Tycho high-performance computing facility, which includes more than 10,000 CPU cores and GPU resources.

NBIA is an international center for fundamental research in theoretical physics. NBIA provides an open intellectual environment where researchers can pursue their own questions and exchange ideas across disciplines. It brings together researchers across astrophysics, gravitational physics, particle physics, quantum sciences, and soft matter physics. NBIA also hosts seminars, international visitors, workshops, and PhD schools. Its research in black-hole dynamics, gravitational-wave modeling, and multimessenger astrophysics offers further opportunities for collaboration. NBIA members interact and collaborate with the larger community of scientists in Copenhagen, including the Center of Gravity, DAWN, DARK, and StarPlan.

Applicants should hold a PhD in astrophysics, physics, or a closely related field by the starting date of the appointment.

• Employees at the University of Copenhagen receive a competitive salary, including pension.
• Denmark offers generous parental leave, subsidized childcare, six weeks of paid vacation, and access to public healthcare.
• Eligible international researchers may also benefit from Denmark’s special researcher tax scheme.
• Copenhagen is a beautiful, family-friendly city with a large international community, a lively and diverse cultural scene, and a very high quality of life.

The University of Copenhagen welcomes all qualified applicants regardless of personal background.
