MICE Simulations

Using the GADGET Tree-PM N-body code on the massively parallel Marenostrum supercomputer (CPU hours awarded: 14+ million), one the most powerful supercomputers in Europe, hosted by the Barcelona Supercomputing Center, we are developing the largest cosmological dark matter simulations to date, involving up to 70 billions of particles in volumes of several thousands of million light-years aside. Our aim is to reproduce, with unprecedented detail, the history of the universe, from much before the first stars formed up to nowadays, and determine how well future astronomical surveys, in which we are involved (such as DES, DESI, PAU, Euclid, and LSST), can answer these fundamental questions. Synthetic galaxy catalogs produced from the MICE simulations are publicly distributed using a dedicated web portal, CosmoHub (cosmohub.pic.es) which currently has 400+ registered users around the world. For further details see the project web.
