| Abstract: |
The simplest scheme for predicting real galaxy properties after performing a dark matter simulation is to rank order the real systems by stellar mass and the simulated systems by halo mass and then simply assume monotonicity -- that the more massive halos host the more massive galaxies. Studying how the scatter in this relation is related to halo properties can give us insight into galaxy formation. I will discuss this method using the IllustrisTNG simulations, first looking for the best halo feature for ranking, then discussing the impact of second-order effects on the stellar mass - halo mass relation.
