论文摘要
乘以成像的时间变量源可用于测量绝对距离作为红移的函数，从而确定宇宙学参数，主要是哈勃常数h $ _0 $。在截至2020年的二十年中，通过许多观察和概念的突破，这种所谓的时间延迟宇宙学已经达到了精确的精确度，足以成为当前“ Hubble张力”辩论的重要独立声音。 2020年代有望在时间延迟宇宙学方面取得重大进展，这是因为新的和即将进行的调查可以发现的大量镜头以及可进行后续和分析的大大改进的功能。在这篇综述中 - 在简要摘要有关该方法的基础和最新进展之后 - 我们概述了十年的机会以及需要克服的挑战，以实现从时间延迟的化妆品中确定h $ _0 $的目标，并具有1 \％的精度和准确性。
Multiply imaged time-variable sources can be used to measure absolute distances as a function of redshifts and thus determine cosmological parameters, chiefly the Hubble Constant H$_0$. In the two decades up to 2020, through a number of observational and conceptual breakthroughs, this so-called time-delay cosmography has reached a precision sufficient to be an important independent voice in the current ``Hubble tension'' debate between early- and late-universe determinations of H$_0$. The 2020s promise to deliver major advances in time-delay cosmography, owing to the large number of lenses to be discovered by new and upcoming surveys and the vastly improved capabilities for follow-up and analysis. In this review -- after a brief summary of the foundations of the method and recent advances -- we outline the opportunities for the decade and the challenges that will need to be overcome in order to meet the goal of the determination of H$_0$ from time-delay cosmography with 1\% precision and accuracy.
