Caterpillar Project The Caterpillar project is an on-going series of state-of-the-art cosmological simulations focusing on halos similar in mass to that of our own Milky Way. The full Caterpillar catalogue consists of 70 dark matter halos at a particle resolution of \({\rm \sim10^4\ M_\odot}\) making it the largest and highest resolution simulation suite in the world to date. These data are enabling us to statistically probe the formation history and evolution of all galaxies of similar size to the Milky Way, including the Milky Way itself!

This website presents the Caterpillar collaboration's key scientific motivations, current progress and media relating to the Caterpillar project.

If you would like more details, please see our flagship paper on ADS.

News! We just published a paper investigating the first stars and galaxies of Milky Way mass systems. Check it out on ADS.
