论文摘要
计划未来重力波（GW）检测器及其将形成的网络的重要步骤是估计其检测和参数估计能力，这是科学研究的基础。已经提出或正在开发几个未来的GW探测器，这也可能同时运行和观察。这些探测器包括陆生，月球和太空探测器。在本文中，我们提出了GWFISH，这是一种新软件，用于模拟GW检测器网络并根据Fisher-Matrix近似计算测量不确定性。 GWFISH模拟了检测器运动对PE的影响，并可以分析不同频段中不同检测器对GW信号的观察。我们展示了爱因斯坦望远镜（ET）的一些例子，包括二进制中子星的天空定位，以及ET测量GWS极化的能力。
An important step in the planning of future gravitational-wave (GW) detectors and of the networks they will form is the estimation of their detection and parameter-estimation capabilities, which is the basis of science-case studies. Several future GW detectors have been proposed or are under development, which might also operate and observe in parallel. These detectors include terrestrial, lunar, and space-borne detectors. In this paper, we present GWFish, a new software to simulate GW detector networks and to calculate measurement uncertainties based on the Fisher-matrix approximation. GWFish models the impact of detector motion on PE and makes it possible to analyze multiband scenarios, i.e., observation of a GW signal by different detectors in different frequency bands. We showcase a few examples for the Einstein Telescope (ET) including the sky-localization of binary neutron stars, and ET's capability to measure the polarization of GWs.
