The impact of different physical models on the formation of Milky Way like galaxies
The formation of galaxies like our own Milky Way are governed by a range of different physical processes such gas cooling and heating via radiation, supernova explosions or cosmic rays. The very details of those processes are able to change the morphology and properties of the galaxies as they evolve. In a series of recent papers I have been studying the impact of different model ingredients on the formation disk galaxies. I focussed thereby on the way star formation is modelled in the simulations or the impact of non-thermal components such as cosmic rays. I found significant differences in galaxy properties when applying different models. Connecting the simulation results to detailed observations of our own Milky Way can help to us constrain galaxy formation models in more detail.
