关于宇宙弦尾迹结构形成的注记

Note on Structure Formation from Cosmic String Wakes

Francis Duplessis, Robert Brandenberger

摘要:

随着精确宇宙学的出现,对宇宙弦的研究重新引起人们的兴趣。在这篇文章中,我们给出了一个定量描述的非线性物质密度波动,可以形成一个宇宙弦尾标度网络。具体来说,我们计算的分布暗物质晕。这些光环在位置空间中具有很强的相关性,应该一直存在到今天。我们还讨论了由于它们的小尺寸和复杂的动力学形成的检测所面临的挑战。

英文摘要:

The search for cosmic strings has been of renewed interest with the advent of precision cosmology. In this note we give a quantitative description of the nonlinear matter density fluctuations that can form from a scaling network of cosmic string wakes. Specifically, we compute the distribution of dark matter halos. These halos would possess strong correlations in position space that should have survived until today. We also discuss the challenges involved in their detection due to their small size and the complex dynamics of their formation.
