Model Description

Milky Way-like N-body models simulated with the parallel GPU tree code Bonsai. Each of the three models consists of a dark matter halo, a classical bulge, and a stellar disk, represented by equal-mass particles of ~170M⊙. The basic dynamical properties of the models are summarized in the following table.

Model Σ8 kpc
