Two postdoctoral positions on observations of early galaxy evolution

We are seeking to fill postdoctoral positions within the REionization Complementary Approach Project (RECAP, an ERC Synergy project), which aims at unravelling the complexity of the cosmic reionization history and of the energy and baryon exchange between ionizing sources and their environment, through the synergy between multi-wavelength observations and multi-scale tailored simulations. The project will exploit data from state-of-the-art facilities, such as ALMA, JWST, and VLT. The design of new observations will be driven by tailored simulations, which will also support the data interpretation. About us The successful applicant will work in the Astronomy and Plasma Physics division, which has a wide range of astronomy topics from exoplanets to high-redshift galaxies. The division is part of the department of Space, Earth and Environment. The department hosts the Swedish National Facility for Radio Astronomy, which is also the location of the Nordic ALMA Regional Center Node.

About the research project Applications are invited for two postdoctoral positions funded by the ERC Synergy Grant 2024 program RECAP. The two positions will be hosted at Department of Space, Earth and Environment, Chalmers University of Technology, Sweden, specifically working in the group of Prof. Kirsten Kraiberg Knudsen, and join for collaboration with other project PIs Laura Pentericci (INAF-Rome), Valentina DOdorico (INAF-Trieste), and Benedetta Ciardi (MPA, Garching). Because of the synergetic approach of the projects, extened visits to institutes other than the hosting one are expected, and the positions comes with travel funds. We seek candidates with the following qualifications: The application should have a PhD, preferably in astronomy, by the start of the appointment. A successful candidate should demonstrate potential for research in extragalactic astronomy and the topic of galaxy formation and evolution. Experience in mm/submm/radio interferometry and/or infrared observations is advantageous.

The position requires sound verbal and written communication skills in English. Swedish is not a requirement but Chalmers offers Swedish courses.

Employment rules give preference to PhD degrees awarded no more than three years prior to the application deadline. * The date shown in your doctoral degree certificate is the date we use, as this is the date you have met all requirements for the doctoral degree. Exceptions from the 3-year limit can be made for longer periods resulting from parental leave, sick leave or military service.

What you will do Your major responsibility as postdoc is to perform research on early galaxy evolution in the research team of Prof. Kirsten Knudsen and within the framework of RECAP. Depending on your role, you will

Position 1: focus on the physical properties of the interstellar medium of early galaxies, in particular on the lower-mass galaxy population.

Position 2: focus on the environment and the properties of companion sources of early galaxies.

Both positions will primarily work from an infrared, mm, and radio wavelength perspective. The positions could also include some possibility for involvement in supervising masters and/or PhD students.

What we offer Chalmers provides a cultivating and inspiring working environment in the coastal city of Gothenburg.

We work broadly with equality projects, for example the GENIE Initiative on gender equality for excellence. Equality and diversity are substantial foundations in all activities at Chalmers.

If Swedish is not your native language, Chalmers offers Swedish courses to help you settle in. Contract terms: This postdoc position is a full-time temporary employment for up to three years.

Application Procedure Please submit your application in English as PDF files according to the instructions below. Each file should not exceed 40 MB. Note: The system does not support Zip files.

• CV, include complete list of publications and contact information to reference persons.

• Describe your previous research fields and main research results
• Describe your future goals and future research focus in the topics of the advertised positions.

• Attested copies of completed education, grades and other certificates.

Reference letters: Please arrange for two reference letters to be emailed directly to Prof Kirsten K. Knudsen (kirsten.knudsen@chalmers.se) by the time of the application deadline. Please ask the reference persons to include the Ref. number and your name in the email subject line.

Please note: The applicant is responsible for ensuring that the application is complete. Incomplete applications and applications sent by email will not be considered.

Application deadline: March 2nd, 2025
