爱因斯坦望远镜（Einstein Telescope, ET）是拟议建于欧洲的地下基础设施，用于搭载下一代引力波（GW）探测器，目前正在研究两种构型：第一种是类似LIGO构型的双站点方案，每个站点设一个L形探测器；第二种是单站点三角探测器。过去十年的大量分析已证明，引力波探测器的分布式网络是科学上更优的方案，但也有观点认为该优势可能不足以否定ET的三角构型。过去对这类构型中噪声关联等方面的建模仅做了表面处理，本文利用ET候选站点的可用数据，引入了ET三角构型中环境噪声的时域模拟，模拟并分析了关联环境噪声以及由环境场瞬变产生的重合 glitch（瞬态干扰），发现这些特征对ET三角构型的观测能力构成重要限制，并限制了其零流（null stream）的效用。
英文摘要
The Einstein Telescope (ET) is a proposed underground infrastructure in Europe to host future generations of gravitational-wave (GW) detectors. Two configurations are under investigation. The first is the two-site solution with an L-shape detector at each site similar to the LIGO configuration. The second configuration is the single-site triangular detector. While numerous analyses over the last decade have already proven that the distributed network of GW detectors is the scientifically preferred solution, it was also argued that the advantage might not be decisive enough to dismiss ET's triangle configuration. The modeling of aspects such as noise correlations in these configurations has only been treated superficially in the past. In this article, we introduce a time-domain simulation of environmental noises in the ET triangle using available data from ET's candidate sites. We simulate and analyze correlated environmental noise as well as coincident glitches produced by transients in the environmental fields. We find that these features pose an important limitation to the observational capabilities of the ET triangle and limit the utility of its null stream.
