1-2 Postdoctoral Researchers’, Senior Research Fellows’ or Project Researchers’ fixed term positions in the Centre of Excellence in Neutron-Star Physics

Position Details (Postdoc)

The Department of Physics and Astronomy at the University of Turku, Finland, invites applications for 1-2 Postdoctoral Researchers, Senior Research Fellows or Project Researchers in High-Energy Astrophysics at the Centre of Excellence (CoE) in Neutron-Star Physics (neutronstars.fi).

These are fixed-term positions with a preferred starting date in August 2026 (or as mutually agreed). The initial appointment is for two years, with the expectation of renewal up to a total of three years for Postdoctoral/Project Researcher positions and up to five years for Senior Research Fellows, contingent on satisfactory performance and the availability of funding.

Job descriptions

The selected researchers are expected to perform cutting-edge research on a topic that has strong synergy with the high-energy astrophysics research conducted in the CoE—particularly in the areas of accreting neutron stars and X-ray polarimetry of compact objects (see sites.utu.fi/hea). Expertise in accretion physics, general relativity, polarimetry, X-ray data analysis, MHD, radiation hydrodynamics, particle-in-cell or Monte Carlo methods will be considered an asset.

A successful Senior Research Fellow is expected to develop and lead an independent research program related to neutron-star physics, with strong synergy with the high-energy astrophysics research conducted at the host institute. Senior fellows are also expected to contribute to the teaching of advanced courses in the department.

The positions offer travel funds, opportunities to work with top physics students, and access to exceptional computing resources, including the LUMI supercomputer and the local computer cluster.

Who we are looking for

We are seeking applicants who are:

Highly motivated and able to work both independently and in a team
Interested in high-energy astrophysics and in particular neutron star physics

Positions are required to have:

the ability to conduct independent scientific work in astrophysics, and the teaching skills necessary for the senior position.
Postdoctoral Researcher and Senior Researcher Fellows: doctoral degree in astrophysics, plasma physics, computational physics, or a related field
Project Researcher: higher university degree astrophysics, plasma physics, computational physics, or a related field

Senior Researcher Fellows are also required to have a proven track record of scientific research work.

The eligibility requirements for the positions must be met by the end of the application period.

We value collegiality and promote equality, diversity, and inclusivity. We encourage all qualified applicants with different backgrounds to apply for our open positions.

Centre of Excellence (CoE) in Neutron-Star Physics

The CoE in Neutron-Star Physics unites experimental, theoretical, numerical, and observational expertise across astrophysics, plasma physics, and nuclear and particle physics. Its overarching goal is to establish a world-leading consortium at the forefront of modern neutron-star research. The CoE aims to advance understanding in several key areas:

Phases of matter in neutron-star cores, including dense-matter equation-of-state physics.
Plasma dynamics in neutron-star magnetospheres, covering both fundamental processes and observable signatures.
Accretion physicsin X-ray pulsars and weakly magnetized neutron stars.
X-ray burst physics, from ignition conditions to burst propagation and radiation processes.
Heavy-element nucleosynthesis in neutron-star mergers, including multimessenger constraints.

By integrating diverse methodologies and expertise, the CoE seeks to deliver breakthroughs that will shape the future of neutron-star physics.
