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.
One essential goal of the project is to take into account the multi-scale problem of galaxy formation: we will deal with a volume corresponding to our "Horizon", i.e. a sphere of radius 13.7 billion of light-years, or 4.27 Gpc. Within this volume, we would like to zoom in towards some large-scale structures that are observed today in giant sky surveys, like super-clusters, and clusters of galaxies, that form at the crossing of cosmic filaments.
Within these galaxy clusters, it is imperative to follow from the beginning the formation of galaxy-scale structures, fueled by matter inflowing within cosmic filaments. Galaxy-scale simulations (20kpc scale, with 20pc resolution) will be carried out taking into account the boundary conditions provided by the large-scale simulations, by means of several levels zoom-in simulations.
The following picture illustrates the multi-scale character of the foreseen simulations.
