演化变星与哈勃常数测量博士研究员（科研助理，TV-L E13/60%）

At the University of Göttingen -Public Law Foundation-, Institut für Astrophysik und Geophysik, there is a position as PhD researcher (all genders welcome) Entgeltgruppe 13 TV-L/60% to be filled. Starting date is 12/1/2026. The position is limited to 3 years.

The part-time position (60%, currently 23.88 hours/week) is intended for a duration of three years at the salary level TV-L E13. The starting date is flexible after 1 December 2026. The position is fully funded by zukunft.niedersachsen, the joint science funding program of the Lower Saxony Ministry of Science and Culture and the Volkswagen Foundation.

The successful applicant will contribute to an improved measurement of the Hubble constant by studying populations of evolved variable stars. The focus will be on statistical stellar standard candles, e.g., the Tip of the Red Giant Branch and J-region AGB methods, with the aim of improving absolute calibrations and the quantification of systematic uncertainties. Access to data from the 4-metre multi-object spectroscopic telescope (4MOST) will be provided, and contributions to the 4MOST project are expected. Data from the ESA Gaia mission and other public datasets (e.g., Roman, Rubin/LSST, OGLE) will complement the analysis. Targeted follow-up observations from the ground or space will be encouraged, e.g., using ESO’s facilities, Hubble and James Webb Space Telescope, or other observatories to which the Institute has access (Euler, MONET, HET). Contributions to the VELOcities of CEpheids (VELOCE) project and the Wide-field Spectroscopic Telescope (WST) are also possible.
