Comparisons between galaxy surveys and hierarchical sturucture formation models are a key driver for progress in understanding galaxy formation. In order to facilitate such comparisons, we propose to establish a website to disseminate simulation data in a manner that may be directly compared against galaxy survey data. The website, called TOGA, will enable users to (1) download photometric catalogs (including physical properties) of simulated galaxies from a suite of state-of-the-art hydrodynamic simulations of galaxy formation, and (2) run an SED fitter on individual galaxy photometry to determine the likelihood that a given observed galaxy can be reproduced in a particular model. These tools will enable detailed comparisons between models and data tailored to individual surveys, and will be particularly useful for high-redshift galaxy studies where Spitzer data is crucial for constraining physical properties. The two tools work together to test predictions of both the bulk properties of galaxies and the properties of individual galaxies, enabling the most comprehensive, detailed, and fair model testing possible. The overall goal is to understand in detail the success and especially the failures of current hierarchical galaxy formation models when compared with the rapidly advancing galaxy survey data. The TOGA website will be operational by Fall 2007, with improvements planned throughout 2008.
