| Outline of Annual Research Achievements |
I have made significant progress in my research on the interplay of cosmological large-scale structure and gravitational wave sources. I shifted the focus to constrain the gravitational wave background with large-scale cosmological simulations. This is due to the fact that the gravitational wave background in the nanohertz regime is dominated by the mergers of supermassive blackholes. The original plan to utilise blackhole mergers in the LIGO-VIRGO-KARGA frequency band turned out to be impossible to resolve with our current state of N-body simulations. Therefore, we shifted the focus on the most massive blackholes we can resolve in simulations.
