Description
In this talk I will introduce Kun, a recently finished high resolution simulation suite for precision cosmology and Chinese Space Station Survey Telescope cosmology science. The Kun suite consists of 129 simulations covering 8 dimensional cosmological parameter space, including dynamic dark energy and massive neutrinos. The CSST Emulator constructed on Kun suite has competitive performance in predicting summary statistics, including matter power spectrum, halo mass function, and basis functions in bias expansion framework. More statistics including weak lensing peak counts are under development. It also provides a base data set for validating the universality of statistics, re-calibrate analytical tools in a wide parameter space, and test the extendability of AI performance.
