Theoretical Astrophysical Observatory

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.

The Theoretical Astrophysical Observatory acknowledges support from the NeCTAR project (, which is funded by the Australian Government through its Super Science initiative and financed by the Education Investment Fund.
