数值模拟解开宇宙网络
Numerical Simulations Unravel the Cosmic Web
摘要:
宇宙被一个由细丝、薄片和结组成的网络所渗透,这些细丝、薄片和结共同形成了一个“宇宙网”。宇宙网的发现,特别是通过星系际介质中的中性氢吸收来自遥远光源的光的特征,证实了理论和实验之间的相互作用,推动了科学的发展,是数值模拟发挥关键和决定性作用的伟大例子之一。我们叙述了我们对宇宙结构的理解的里程碑,总结了它对天文学,宇宙学和物理学的影响,并通过概述我们准备在新的波长探测宇宙网络时所面临的挑战来展望未来。
英文摘要:
The universe is permeated by a network of filaments, sheets, and knots collectively forming a "cosmic web.'' The discovery of the cosmic web, especially through its signature of absorption of light from distant sources by neutral hydrogen in the intergalactic medium, exemplifies the interplay between theory and experiment that drives science, and is one of the great examples in which numerical simulations have played a key and decisive role. We recount the milestones in our understanding of cosmic structure, summarize its impact on astronomy, cosmology, and physics, and look ahead by outlining the challenges faced as we prepare to probe the cosmic web at new wavelengths.
