下一代引力波探测器的探测器

Metrics for next-generation gravitational-wave detectors

Evan D Hall, Matthew Evans

摘要:

引力波天体物理学有可能被一个更长、更冷、因而更灵敏的探测器组成的全球网络所改变。这个网络必须被构建以解决广泛的科学目标,包括二元聚结信号以及来自其他潜在未知来源的信号。了解哪些网络配置-网络中检测器的数量,类型和位置-可以最好地实现这些目标至关重要。在这项工作中,我们研究了大量可能的三探测器网络,由旅行者号,爱因斯坦望远镜和宇宙探测器探测器组成,并评估了它们的性能,以获得各种未来科学目标。由此我们推断,网络性能,包括天空定位,是由网络中包含的探测器的类型,而不是设施的位置和方向决定的。

英文摘要:

Gravitational-wave astrophysics has the potential to be transformed by a global network of longer, colder, and thus more sensitive detectors. This network must be constructed to address a wide range of science goals, involving binary coalescence signals as well as signals from other, potentially unknown, sources. It is crucial to understand which network configurations---the number, type, and location of the detectors in the network---can best achieve these goals. In this work we examine a large number of possible three-detector networks, variously composed of Voyager, Einstein Telescope, and Cosmic Explorer detectors, and evaluate their performance against a number of figures of merit meant to capture a variety of future science goals. From this we infer that network performance, including sky localization, is determined most strongly by the type of detectors contained in the network, rather than the location and orientation of the facilities.
