丽莎是一个计划中的天基引力波（GW）探测器，它对低频源的波敏感，大约在（0.03 - 0.1）mHz到0.1 Hz的波段。预计这将是GW光谱中非常丰富的一部分-观测这些波将为天体物理学中的动力学过程提供独特的视角。在这里，我们给出了一些关键的丽莎来源的快速调查，以及GWs可以独特地教我们关于这些来源。特别值得注意的科学是，这里强调的是丽莎通过测量大质量黑洞双星产生的GWs（这反过来又是由星系和原星系合并形成的）来跟踪黑洞质量和自旋的中度到高度红移演化的潜力。测量这些二元黑洞波有可能以百分比级或更高的精度确定组成黑洞的质量和自旋，为早期结构生长的一个方面提供独特的高精度探针。这篇文章是基于…
LISA is a planned space‐based gravitational‐wave (GW) detector that would be sensitive to waves from low‐frequency sources, in the band of roughly (0.03 – 0.1) mHz ≲ f ≲ 0.1 Hz. This is expected to be an extremely rich chunk of the GW spectrum — observing these waves will provide a unique view of dynamical processes in astrophysics. Here we give a quick survey of some key LISA sources and what GWs can uniquely teach us about these sources. Particularly noteworthy science which is highlighted here is the potential for LISA to track the moderate to high redshift evolution of black hole masses and spins through the measurement of GWs generated from massive black hole binaries (which in turn form by the merger of galaxies and protogalaxies). Measurement of these binary black hole waves has the potential to determine the masses and spins of the constituent black holes with percent‐level accuracy or better, providing a unique high‐precision probe of an aspect of early structure growth. This article is based on ...
