【摘要】：正由北京師范大學(xué)天文系張同杰教授主導(dǎo)的宇宙中微子數(shù)值模擬團(tuán)隊(duì),運(yùn)用國(guó)防科技大學(xué)研制的"天河二號(hào)"超級(jí)計(jì)算機(jī),成功完成了3萬(wàn)億粒子數(shù)的宇宙中微子和暗物質(zhì)數(shù)值模擬,揭示了宇宙大爆炸1600萬(wàn)年之后至今約137億年的漫長(zhǎng)演化進(jìn)程.在模擬中首次測(cè)量到了中微子在宇宙結(jié)構(gòu)中的微分凝聚(Differential Neutrino Condensation)效應(yīng),這種效應(yīng)為當(dāng)今和將來(lái)的宇宙學(xué)觀測(cè)開(kāi)辟了一條獨(dú)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.
