论文摘要
激光干涉仪空间天线（LISA）的重要目标是观察随机重力波背景（SGWB）。对LISA中可能相关噪声的研究与为未来的测量建立限制有关。为了测试在某种逼真的条件下的噪声调查方法，我们使用Lisa Pathfinder（LPF）的数据。我们计算了两个测试材料的LPF差分加速度之间具有磁场，温度和Micronewton冷气油推进器在航天器中的相干性。我们将观察到的相关性应用于丽莎，并估计这种相关噪声的存在如何影响其对SGWB的搜索。在功绩图的背景下，我们估计噪声对LISA SGWB搜索的影响。
An important goal of the Laser Interferometer Space Antenna (LISA) is to observe a stochastic gravitational-wave background (SGWB). A study of possible correlated noise in LISA is relevant to establish limits for this future measurement. To test noise investigation methods under somewhat realistic conditions, we use the data of LISA Pathfinder (LPF). We calculate the coherence between the LPF differential acceleration of the two test-masses with magnetic fields, temperature, and micronewton cold gas thruster activity in the spacecraft. We apply our observed correlations to LISA, and estimate how the presence of such correlated noise would affect its search for a SGWB. In the context of a figure of merit, we estimate the effect of noise on the LISA SGWB search.
