Researcher in Astrophysics

Lund University was founded in 1666 and is consistently ranked among the world's leading institutions of higher education. It is home to approximately 47,000 students and more than 8,800 employees in Lund, Helsingborg, and Malmö. We are united in our quest to understand, explain, and improve our world and the conditions of human life. Lund University welcomes applicants from diverse backgrounds and experiences. Equality, equal opportunities, and diversity are fundamental principles for all aspects of our operations. The position is based in the Department of Astrophysics within the Department of Physics, working in Professor Nils Ryde's group to conduct advanced and independent research in galactic archaeology using precision stellar spectroscopy in the near-infrared. The aim is to achieve a deeper understanding of the physical processes driving the development of the Milky Way's center, particularly focusing on better understanding its star formation history. The necessary chemodynamic studies will provide insights into the history of chemical enrichment and the formation and evolution of various components and star populations. The researcher will lead the efforts to scientifically analyze data from the IGRINS spectrometer and develop precision tests for data expected from the planned VLT/MOONs spectroscopic facility at ESO. The first data is anticipated in about a year, in 2026. Studies of star populations obscured by interstellar dust, such as those in the center of the Milky Way, will be specifically conducted, but general studies on the cosmic origin of elements will also be carried out. This research is supported by the Swedish Research Council. We offer Lund University is a government agency, which means you will receive specific benefits, generous vacation days, and a favorable occupational pension.

The employee will lead the efforts in the project and will independently work on: - Developing existing spectroscopic methods for determining stellar parameters. - Developing methods for accurate determination of stellar abundances in high-resolution stellar spectra in the near-infrared spectral bands based on studies of atomic physics transitions. - Performing high-quality analyses of these studies based both on Gemini/IGRINS data and data from the upcoming MOONs spectrometer. The analysis of these data must be developed carefully to achieve the highest level of precision and accuracy. The researcher will have a degree of freedom to develop the scientific direction as the project evolves. The employee is expected to publish scientific articles, present at international conferences, visit other research institutes, and hold seminars. This will involve some travel, for which a budget is available, but the employee is also expected to apply for travel funding from external sources, such as scholarly societies and research councils. The collaborator is expected to contribute to the group's daily scientific activities and participate in meetings with partners in Lund and elsewhere where we share research results and engage in scientific discussions. The tasks will include: - Analysis and determination of atomic transitions in the near-infrared spectral range. - Development of spectroscopic methods. - Scientific analysis of IGRINS and MOONs data. - Training of undergraduate and master's students in stellar spectroscopy. - Collaboration and participation within the ISA research group in the Department of Astrophysics. Requirements for the Position - A completed PhD related to stellar astrophysics and galactic archaeology. - A strong ability to develop and conduct high-quality research. - The applicant should specialize in galactic archaeology and have training in stellar spectroscopy in the optical or near-infrared, along with relevant method development. - Documented independence and good collaborative skills. Desirable Experience and Knowledge for the Position - Experience in star spectroscopic analysis at both low and high resolution in the near-IR, specifically analyses using the SME program. - Experience participating in large astronomical collaborations such as the PRISTINE survey or Gaia-ESO. - Knowledge of high-precision spectroscopy of K and M giants using IGRINS data. - Proficiency in Python, IDL, TOPCAT, and other programming languages. - Strong track record of presenting at international conferences and seminars. Conditions The position is temporary for 6 months, full-time, starting from January 1, 2026, but no later than March 1, 2026. Application Instructions The application must be written in English and include: - A CV including a publication list. - A general description of previous research work and future research interests, specifically within the subject area (maximum two pages). - A copy of the doctoral degree certificate and any other certificates or transcripts you wish to submit. We look forward to receiving your application! At the Faculty of Science, research and education are conducted in biology, astronomy, physics, geosciences, chemistry, mathematics, and environmental science. The activities are carried out across eight departments located in the northern university area. The faculty has
