It is generally believed that feedback from supermassive black holes has a significant impact on the formation and evolution of massive galaxies, galaxy groups and clusters. In this talk, I present our recent progress in modeling these feedback effects in cosmological simulations of galaxy formation that reach ~kpc resolutions and show its effects on the simulated galaxy population. In particular, I will present first results of the IllustrisTNG simulations, a recently completed set of follow-up simulations of the Illustris project, focusing on the effect of AGN on a variety of observables from galactic to cosmic scales. Towards the end, I will give an outlook on how future feedback models in cosmological simulations can be more predictive. I will present a high resolution study of AGN jets interacting with the surrounding intra-cluster medium and show how we can systematically use idealized, high resolution simulations to understand the small-scale feedback physics and to develop more predictive sub-resolution models for future simulation projects.
