Research Interest

I joined the star formation group at ITA in 2015 for my Bachelors thesis. Since then I have been researching in the formation life and death of the first (i.e. Population III) stars with a focus on feedback and observational signatures of their properties.

Population III stars are special in several aspects: being the first stars that formed they must form from metal-free gas. This should impact their formation process such that they are typically short-lived and more massive than stars in the present day Universe. They are the first sources of light and end the cosmic dark ages. As they form the first metals in their cores and thus lay the basis for all subsequent generation of metal-enriched stars. Finally, no Population III star has been found until today.

In close collaboration with Tilman Hartwig I worked on the semi-analytical model of Population III star formation and feedback A-SLOTH. Our model is computationally efficient and can be used to shed light on many aspects the formation of the first stars. This model has been applied to a number of different questions surrounding the formation of the most metal-poor stars and the high-redshift Universe. The code is anticipated to be released in the coming months. If you would like advanced access to the source code of our model, please contact me or Tilman Hartwig. The second leg of my research is a large numerical simulation on how metals spread and mix after the first supernovae. For this project we employ the moving-mesh hydrodynamics code Arepo. The first results of these simulations are available in Magg et al. 2021<\a>.
