论文摘要
宇宙空隙是宇宙中的不足区域，受到暗能和大量中微子的影响。在这项工作中，依靠宇宙学模拟的Demnuni套件，我们探索了具有动态性暗能量和大量中微子的宇宙学中的空隙尺寸函数。我们研究了暗物质示踪剂对空隙尺寸函数的不同选择的影响，并研究了其对修改状态的暗能量方程和中微子质量之和的关节效应的敏感性。我们表明，暗能量和大量中微子对空隙尺寸函数产生可分离的影响。因此，该统计数据使我们能够区分状态和总中微子质量的深色能量方程组合，并且其在即将进行的大型星系调查中的剥削对于破坏这些宇宙学参数的脱糖性非常有用。
Cosmic voids, the underdense regions in the Universe, are impacted by dark energy and massive neutrinos. In this work, relying on the DEMNUni suite of cosmological simulations, we explore the void size function in cosmologies with both dynamical dark energy and massive neutrinos. We investigate the impact of different choices of dark matter tracers on the void size function and study its sensitivity to the joint effect of modifying the dark energy equation of state and the sum of neutrino masses. We show that dark energy and massive neutrinos produce separable effects on the void size function. This statistic therefore allows us to distinguish among a wide range of combinations of dark energy equations of state and total neutrino masses, and its exploitation in forthcoming large galaxy surveys will be extremely useful in breaking degeneracies among these cosmological parameters.
