Research position (m/f/d) (PhD student) in the field of cosmology
The Cosmology and Astroparticle Physics group investigates the formation and evolution of large-scale structures in the Universe, the nature of dark matter, 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, Rubin LSST and SKA.
The PhD project focuses on galaxy clustering and weak lensing probed by galaxy and radio surveys such as Euclid and SKA. You will work on developing methods to extract cosmological and astrophysical parameters from beyond two-point statistics. You will incorporate new physical effects into existing theoretical methods and include systematics relevant for observational data, validate predictions with simulated data and perform data analysis of mock and real galaxy survey data. You will conduct research independently and in collaboration with small international teams and large collaborations, and present your results in scientific publications and meetings. (78%)
The supervision of exercise groups (tutorials) and the support of Master and Bachelor students in the research group is also part of the tasks (the teaching load is 2.6 hours per week). (22%)
