A three-year postdoctoral position in astronomy is available at the Department of Physics at KTH Royal Institute of Technology in Stockholm, Sweden. The successful candidate will join the research group of Professor Josefin Larsson and focus on research related to supernova remnants. The position emphasizes the analysis and interpretation of observational data from both space- and ground-based facilities, including the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST). Research directions may include studies of ejecta structure and composition, circumstellar interaction, and pulsar wind nebulae, with flexibility to tailor projects to the candidate’s expertise and interests. The postdoctoral fellow will have the opportunity to participate in the supervision of master’s and/or PhD students. Astrophysics research at KTH is part of the Oskar Klein Centre for Cosmoparticle Physics (OKC) at the AlbaNova University Centre, which offers a vibrant international research environment and a large community of researchers working on supernovae. The OKC hosts a broad range of activities, seminars, and collaborations, supporting a dynamic and stimulating research atmosphere. Applicants must have a doctoral degree or an equivalent foreign degree by the time of employment decision. A strong research track record, demonstrated through high-quality publications, and experience in the analysis of observational astronomical data are required. Preferred qualifications include a doctoral degree obtained within the last three years, research experience on supernova remnants or a closely related field, experience with supervision and teaching, strong collaborative skills, the ability to work independently, and awareness of diversity and equal opportunity issues, with a focus on gender equality. The position is full-time for up to three years, with a monthly salary and attractive benefits provided by KTH. The start date is according to agreement. The application should include a CV, publication list, cover letter (maximum two pages), and names and contact information for two referees.

Doctoral student in Astrophysics at KTH Royal Institute of Technology, Sweden. This PhD position is hosted by KTH’s astrophysics research environment and linked to the Oskar Klein Centre for Cosmoparticle Physics (OKC) at AlbaNova University Centre. The project focuses on X-ray astronomy, especially emission from supernovae and supernova remnants, and uses observational data, data mining, and other data-intensive methods to investigate the properties of compact objects formed in supernova explosions. The work will make use of major X-ray observatories such as XMM-Newton and Chandra, together with complementary multiwavelength observations from other facilities. The successful doctoral student will join the research group of Professor Josefin Larsson and may collaborate on related projects involving infrared and optical studies of supernova remnants. The wider environment at KTH also includes instrumentation development for X-ray astronomy and studies of gamma-ray bursts. Through OKC, the student will be part of an active international community with seminars, collaborative opportunities, and a strong concentration of researchers working on supernovae and related topics. Eligibility requirements include a second-cycle degree (for example, a master’s degree), at least 240 higher education credits with at least 60 second-cycle credits, or equivalent knowledge, with the basic academic background in astronomy or physics. English proficiency equivalent to English B/6 is mandatory. Preferred experience includes an MSc project in astronomy, experience with astronomical data analysis, and strong written and oral communication skills. KTH also stresses goal orientation, perseverance, independent work, collaboration, professionalism, and the ability to analyse complex issues. Funding is provided as a doctoral student employment position with monthly salary according to KTH’s doctoral student salary agreement. The position is full time and temporary, with admission only possible for those accepted to doctoral education. The planned start is beginning of 2027 or earlier. Applications must be submitted through KTH’s recruitment system by 2026-10-06. Required documents include diplomas and transcripts, proof of language qualifications, a CV, a short motivation/application letter, and representative publications or technical reports.
