## Tracing the first stars and galaxies of the Milky Way

We use 30 high-resolution dark matter haloes of the Caterpillar simulation suite to probe the first stars and galaxies of Milky Way-mass systems. We quantify the environment of the high-z progenitors of the Milky Way and connect them to the properties of the host and satellites today.

## The Caterpillar Project: A Large Suite of Milky Way Sized Halos

We present the largest number of Milky Way sized dark matter halos simulated at very high mass ($\sim$\ $10^4$ \Msol/particle) and temporal resolution (5 Myrs/snapshot) done to date, quadrupling what is currently available in the literature.
