论文摘要
随着天然和太极的最新发展，我们现在有越来越多的机会通过与丽莎一起运行MHz频段进行相关分析。假设在一般几何结构下有两个类似Lisa的三角形检测器，我们开发了一种简单的公式来评估网络对各向同性引力波背景的敏感性。在我们的公式中，我们完全使用每个三角形检测器中数据通道的对称性，并提供可拖动的表达式，而无需直接使用繁琐的检测器张量。我们对包括Lisa-Tianqin对在内的各种潜在检测器组合的预期网络敏感性进行了具体评估。
With the recent strong developments of TianQin and Taiji, we now have an increasing chance to make a correlation analysis in the mHz band by operating them together with LISA. Assuming two LISA-like triangular detectors at general geometrical configurations, we develop a simple formulation to evaluate the network sensitivity to an isotropic gravitational wave background. In our formulation, we fully use the symmetry of data channels within each triangular detector and provide tractable expressions without directly employing cumbersome detector tensors. We concretely evaluate the expected network sensitivities for various potential detector combinations, including the LISA-TianQin pair.
