Theoretical Astrophysical Observatory - Simulated Data and Models

Brief description

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 Input data:

Each simulation and galaxy model contains a vast array of properties. The following is a brief description of the simulated data and models contained in the Theoretical Astrophysical Observatory.
