Living with Neighbors. II. Statistical Analysis of Flybys and Mergers of Dark Matter Halos in Cosmological Simulations

We present a statistical analysis of the flybys of dark matter halos compared to mergers, using cosmological N-body simulations. We mainly focus on gravitationally interacting target halos with mass of 1010.8-1013.0 h−1M , and their neighbors are counted only when the mass ratio is 1:3-3:1 and the d...
