报告摘要

In this talk I will introduce Kun, a recently finished high resolution simulation suite for precision cosmology and China Space Station 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 base functions in bias expansion framework. More statistics including weak lensing and base components in halo model framework 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.
