The main goal of the Skies and Universes website is to provide access for the astronomical community with results from cosmological simulations. These results are useful on their own to understand processes related with the non-linear evolution of cosmic structures. Some other products are specifically focused on large survey observational projects. To facilitate the interaction between the theory and observations we also provide links to recent observational projects.There are other databases and websites that provide access to results of simulations. Their links can also be found here.

Specifics of our portal is that it provides raw data of simulations. For example, one can find here coordinates and velocities of simulations with billions of particles. We also provide halo catalogs, light-cones for mock galaxy/qso samples, power spectra for many thousands of N-body realizations and some observational products. While we provide some assistance in the form of codes to read the data, it is responsibility of users to write their own analysis software. Unlike the and Millennium databases, we do not support SQL queries. Users of Skies & Universes are expected to download data and write their own routines to analyze the data. At present we do not provide computing facilities to do the analysis.

Downloading files: You are welcome to use more than 30Tb of raw data on this site. However, special care should be given when downloading large files. Please, do not download all of the large files at once. You will not get anything, if you do. Get 1-2 files, wait until the downloading finishes and then get another bunch files.
