The Theoretical Astrophysical Observatory (TAO) houses queryable data from multiple popular cosmological simulations and galaxy formation models.Results can be funnelled through higher-level modules to build custom mock galaxy catalogues and images. TAO is accessible from anywhere you can access the internet.
TAO is part of the All-Sky Virtual Observatory (ASVO) and is funded and supported by Astronomy Australia Limited, the National eResearch Collaboration Tools and Resources (NeCTAR) , and Swinburne University of Technology.
