Welcome to CSST Emulator’s documentation!
CSST Emulator is a cosmological emulator for China Space Station Telescope (CSST) optical survey. This is a pure Python package that provides a simple and intuitive API for predicting the commonly used statistics, e.g., matter power spectrum. We use the Kun (鲲, in Chinese) Suite as the training data, which includes 129 high-resolution N-body simulations, which are generated by the modified version of the Gadget-4 code with 129 different cosmologies. So it can achieve a high accuracy in a wide range of cosmological parameters as followed.
