Here you find the HOD for AGN with high and low Eddington ratio.

About my work:

I’m a Postdoc in Astronomy at the USM in Munich, where I work in the Computational Astrophysics (CAST) group. My supervisor is Klaus Dolag and we work with a set of large scale cosmological simulations called the Magneticum Pathfinder Simulations. When I started with my Master thesis in 2013 we had the first cosmological simulations with a resolution high enough to resolve the morphology of galaxies! A few years later we started to publish papers about these simulations (e.g. Teklu et al. 2015, Remus et al. 2015, Steinborn et al. 2016).

My PhD thesis was about Active Galactic Nuclei (AGN) in cosmological simulations. I’m especially interested in improvements of the feedback and accretion model used in cosmological simulations since I found that it can have a huge effect onto not only black hole growth but also onto the host galaxy (Steinborn et al. 2015).

Besides coding I’m also very interested in the question what triggers AGN. With our simulations we have the huge advantage that we can trace galaxies back in time. Although we find a correlation between galaxy mergers and AGN, our simulations suggest that mergers are not very relevant for the overall AGN population (Steinborn et al 2018).
