Theoretical Astrophysics Observatory

The Theoretical Astrophysical Observatory (TAO) houses data from popular cosmological simulations and galaxy formation models for community use, primarily focused on galaxy survey science. Mock catalogues observed through virtual telescopes can be built by anyone without the need for any coding. This DOI refers to the raw TAO data repository stored on the OzSTAR supercomputer at You can contact the data owner if you would like to discuss becoming a collaborator to gain access to this data.

TAO is also accessible to all astronomers and the public from anywhere they can access the internet via
