空间引力波观测站

Space-based Gravitational Wave Observatories

Jonathan R Gair, Martin Hewitson, Antoine Petiteau, Guido Mueller

摘要:

本文将作为《引力波天文学手册》的一章出现,我们将在本文中描述利用天基干涉引力波观测站探测引力波的情况。我们将提供一个概述的关键技术,其操作,说明使用激光干涉仪空间天线(LISA)的具体例子。然后,我们将概述天基探测器的数据分析战略,包括对时间延迟干涉测量法的描述,这是将激光频率噪声抑制到必要水平所必需的。我们将描述天基探测器瞄准的毫米赫兹频率范围内的引力波的主要来源,然后讨论这些观测将促进的一些关键科学研究。再次,这里给出的定量陈述将参考LISA的能力,因为这是研究得最好的任务概念。最后,我们将介绍关于今后可能进一步发射的更灵敏的天基探测器的一些建议。

英文摘要:

In this article, which will appear as a chapter in the Handbook of Gravitational Wave Astronomy, we will describe the detection of gravitational waves with space-based interferometric gravitational wave observatories. We will provide an overview of the key technologies underlying their operation, illustrated using the specific example of the Laser Interferometer Space Antenna (LISA). We will then give an overview of data analysis strategies for space-based detectors, including a description of time-delay interferometry, which is required to suppress laser frequency noise to the necessary level. We will describe the main sources of gravitational waves in the millihertz frequency range targeted by space-based detectors and then discuss some of the key science investigations that these observations will facilitate. Once again, quantitative statements given here will make reference to the capabilities of LISA, as that is the best studied mission concept. Finally, we will describe some of the proposals for even more sensitive space-based detectors that could be launched further in the future.
