【摘要】：正由北京师范大学天文系张同杰教授主导的宇宙中微子数值模拟团队,运用国防科技大学研制的"天河二号"超级计算机,成功完成了3万亿粒子数的宇宙中微子和暗物质数值模拟,揭示了宇宙大爆炸1600万年之后至今约137亿年的漫长演化进程.在模拟中首次测量到了中微子在宇宙结构中的微分凝聚(Differential Neutrino Condensation)效应,这种效应为当今和将来的宇宙学观测开辟了一条独立
[Abstract]:The cosmic neutrino numerical simulation team, led by Professor Zhang Tongjie, Department of Astronomy, Beijing normal University, uses the "Tianhe 2" supercomputer developed by the University of National Defense Science and Technology. The numerical simulation of neutrino and dark matter in the universe with 3 trillion particles has been successfully completed, which reveals the long evolution of the universe 1600 million years after the Big Bang and about 13.7 billion years up to now. The differential Neutrino condensation effect of neutrino in cosmic structure has been measured for the first time in the simulation. This effect opens up an independent field for the cosmological observation in the present and future.
