A workshop dedicated to the Theoretical Virtual Observatory will take place at IAP on April 5-6th.
The goal is to bring together experts of the Virtual Observatory and theoreticians who would like to make results of their simulations (e.g. databases or catalogs) or numerical codes available to the worldwild astronomical community.
Mock galaxy catalogs can be produced from numerical simulations. Various types of catalogs are available :
Complete galaxy catalogs can be produced from simulations of large cosmological volumes. These catalogs give the statistical properties of the whole population of galaxies, and can be used as reference predictions to be compared with magnitude or volume limited surveys.
Selected galaxy catalogs can be produced from a large set of numerical simulations of astrophysical situations, e.g. cluster galaxies, galaxy encouters, or galaxy merging. These catalogs can be used as reference predictions to be compared with surveys that focus on selected types of objects.
The Horizon project has produced these 2 types of catalogs.
