Welcome

The Caterpillar Project is a large suite of dark matter only cosmological simulations of 35 Milky Way-sized galaxies. At a resolution of ∼10⁴ M_⊙ per particle and 50 Myr temporal resolution, it is one of the largest and highest resolution simulation suites of its kind in the world.

These data are enabling us to statistically probe the formation history and evolution of the Milky Way and its similar sized cousins.
