Job description

The present position is for a PhD Fellow to join the Extragalactic Astrophysics group and do a thesis project supervised by Prof. Sijing Shen. The research work will be focused on numerical galaxy formation and the interactions between galaxies and their environment. In particular, the successful candidate will be involved in the ESA ARRAKIHS satellite mission with the main goal of understanding the impact of dark matter models and baryonic processes in faint substructures (e.g., dwarf satellites and stellar tidal streams) around disk galaxies. 

The successful candidate will design, perform and analyse idealized and cosmological hydrodynamical galaxy formation simulations, develop or improve models for important physical processes which impact galaxy evolution, such as dark matter models, gas accretion, star formation, black hole formation and evolution, and radiative or mechanical feedback from stars and active galactic nuclei. The successful candidate will also post-processing large sets of simulation data and make detailed comparison with multi-wavelength observations of the stellar and gaseous components. The successful candidate will have ample opportunities to collaborate with both simulators and observers worldwide and travel for conferences and collaborative visits.
