论文摘要
基于地面的重力波干涉仪可以直接探测超轻暗物质的存在（$ \ natercal {o}（10^{ - 14} -10} -10^{ - 11}）$ ev/$ ev/$ ev/$ c^2 $）将其与检测器中的标准模型粒子偶联。最近，已经开发了许多技术来从嘈杂的引力波数据中提取各种潜在的暗物 - 物体信号。但是，很少有努力进入区分可能直接与干涉仪相互作用的暗物质类型的方法。在这项工作中，我们采用Wiener过滤器来跟进候选候选深色互动信号。该过滤器捕获了这些信号的随机性质，并在模拟中成功识别了哪种暗物质与干涉仪相互作用。我们将Wiener过滤器应用于留在Ligo/处女座/Kagra中的离群值中，从最新观察（O3）中的数据中搜索了深色光子，并表明它们与噪声干扰一致。我们的概念验证分析表明，Wiener滤波器可以是一种强大的技术，可以在重力波数据中确认或否认存在深色 - 物体相互作用信号，并区分标量和矢量深色 - 深色相互作用。
Ground-based gravitational-wave interferometers could directly probe the existence of ultralight dark matter ($\mathcal{O}(10^{-14}-10^{-11})$ eV/$c^2$) that couples to standard-model particles in the detectors. Recently, many techniques have been developed to extract a variety of potential dark-matter signals from noisy gravitational-wave data; however, little effort has gone into ways to distinguish between types of dark matter that could directly interact with the interferometers. In this work, we employ the Wiener filter to follow-up candidate dark-matter interaction signals. The filter captures the stochastic nature of these signals, and, in simulations, successfully identifies which type of dark matter interacts with the interferometers. We apply the Wiener filter to outliers that remained in the LIGO/Virgo/KAGRA search for dark photons in data from the most recent observing (O3), and show that they are consistent with noise disturbances. Our proof-of-concept analysis demonstrates that the Wiener filter can be a powerful technique to confirm or deny the presence of dark-matter interaction signals in gravitational-wave data, and distinguish between scalar and vector dark-matter interactions.
