Hyper-Millennium project: a hyper cosmological simulation for the next generation of large-scale structure survey

郭琦(国家天文台)


Abstract

Dark matter and dark energy are among the most important cutting-edge sciences. Extensive global efforts have been dedicated to the large-scale structure evolution through projects like LSST, DESI, Euclid, PFS, and the Chinese space station optical survey. We have successfully completed a N-body cosmological simulation that traces 4 trillion particles from redshift 100 to the present day within a 2.5 Gpc/h box. The particle mass is 3.2 x 10^8 solar masses, meeting the requirements for the next generation of large-scale structure surveys. This simulation aids in understanding the systemic and statistical uncertainties involved in studying large-scale structure formation, including baryon acoustic oscillations, redshift distortion, weak lensing, high redshift AGNs and etc. In my presentation, I will delve into the details of the simulation and discuss advancements made in galaxy and AGN formation modelsas well as some applications.
