cosmological simulations

Our group performs some of the largest cosmological N-body simulations in the world.  We have publicly available data from several of these projects, including LasDamas, the Dark Sky Simulations, the Aemulus Project, UNITSIM, and a variety of high resolution zoom-ins.

analysis tools

Accurate analysis tools for cosmological simulations are essential to our work.  Our group has pioneered accurate halo finding and merger tree tools, as well as tools for connecting galaxies to halos and analyzing the properties of halos and the matter distribution.

simulated sky surveys

 The current and next generation of cosmological sky surveys depend on the predictions of simulated sky surveys that include realistic galaxy populations.  The most recent simulation suite can be found here:
