Postdoctoral positions and DAWN Postdoctoral Fellowship at the Cosmic Dawn Center

The Cosmic Dawn Center (DAWN) invites applications for both the DAWN Postdoctoral Fellowship and postdoctoral positions to work on specific projects.

DAWN is a Center of Excellence funded by the Danish National Research Foundation (DNRF) and is located in the Copenhagen area at the Niels Bohr Institute (NBI), University of Copenhagen and the Space division of the Danish Technical University (DTU-Space). In addition, DAWN has several associates at major research institutes across Europe, North America, and Australia.

DAWN brings together experts in all aspects of early Universe research and is deeply involved in major existing and upcoming surveys with JWST and HST (e.g. SPURS, COSMOS3D, FRESCO, COSMOS-Web, RUBIES, BEACON, and CLUTCH), ALMA (e.g. CHAMPS), and Euclid (e.g. Cosmic Dawn Survey of the deep fields), as well as simulations.

DAWN Postdoctoral Fellowships

DAWN Postdoctoral Fellowships are intended for outstanding scientists whose research falls within DAWN’s research themes focused on the early Universe: first stars, high-redshift galaxy evolution, reionization and evolution of the IGM, high-redshift transients and supernovae, dust and ISM in the early Universe, massive galaxy evolution, and dark matter. DAWN Postdoctoral Fellows are expected to pursue their own independent, cutting-edge research programs in collaboration with DAWN members.

Postdoctoral positions

Up to two postdoctoral position are available as part of the DFF Sapere Aude-funded project “Revealing Massive Stars at Cosmic Dawn” in Associate Professor Charlotte Mason’s group at DAWN/NBI to work on both observational and theoretical projects on galaxy formation and reionization, with a particular focus on JWST spectroscopy from the SPURS survey.

Applicants with interests and expertise in any of galaxy formation, stellar populations, Lyman-alpha emission, IGM/CGM evolution, galaxy-dark matter connections at high redshift, JWST NIRSpec spectroscopy, statistical inference and comparing hydrodynamical simulations to observations are strongly encouraged to apply.

Additional postdoctoral positions may be available to work on specific projects at DAWN funded through individual group leadership grants. Applicants with research interests in any of the above DAWN research themes are strongly encouraged to apply.

Applicants to this position will be automatically considered for all available postdoctoral and Postdoctoral Fellowship positions at DAWN/NBI. We note a separation application is required for applications to the positions at DAWN/DTU in the group of Associate Professor Kasper Heintz.

DAWN Postdoctoral Fellows and postdocs are encouraged to collaborate with DAWN’s international associates, and have the opportunity to supervise students and to apply for grants and observing proposals as PI.
