The Faculty of Physics has the following job opening in the "Cosmology Working Group":
Research position (PhD student) in the field of cosmology
ID: Wiss25096
- starting: 01.10.2025
- part-time 65 %
- salary according to Remuneration level 13 TV-L
- fixed-term
The Cosmology and Astroparticle Physics group investigates the formation and evolution of large-scale structures in the Universe, the nature of dark matter and dark energy, and the physics of the early Universe. We use theoretical, statistical and numerical tools in combination with observational data from optical and radio surveys such as Euclid, LOFAR and SKA.
The distribution of galaxies and the underlying matter (observed by the weak gravitational lensing effect) studied by the Euclid space telescope will provide unique insights into the history and composition of our Universe. As part of the ERC project "Probing cosmic large-scale structure beyond the average", the PhD project focuses on the development of methods to extract fundamental physical data beyond two-point statistics. These are crucial to extract non-Gaussian information missing in the standard two-point statistics and thus maximise the scientific return of current and future galaxy surveys. In particular, our group is working on one-point statistics and density-dependent statistics for the distribution of galaxies and the underlying matter.
You will contribute to an active and positive research culture in the group, for example by supporting Master's and Bachelor's students in their research (10%).
Employment is conducive to academic qualification.

Your Tasks
You will extend existing theoretical methods with new physical effects and incorporate systematics relevant to observational data, validate predictions with simulated data and perform analyses of simulated and real observational data. You will conduct research independently and in co-operation with small international teams and large collaborations and present your results in scientific publications and at conferences (90 %).You will contribute to an active and positive research culture in the group, for example by supporting Master's and Bachelor's students in their research (10%).
Employment is conducive to academic qualification.
