Notes. The TNG300-1 simulation (Nelson et al. 2019) is used as reference for the analysis, and we compare to it the results obtained with Magneticum (Hirschmann et al. 2014; Dolag 2015). TNG300-2 is compared to the reference TNG300-1 to asses the effect of resolution. TNG100-2 and Illustris-2 simulations (Genel et al. 2014; Vogelsberger et al. 2014; Nelson et al. 2015) are compared to each other to study the effects of the intrinsic physical models on our results.
