用干涉测量法探测引力波(地面和空间)

Gravitational Wave Detection by Interferometry (Ground and Space)

Matthew Pitkin, Stuart Reid, Sheila Rowan, Jim Hough

摘要:

近年来,引力波探测器的研制取得了重大进展。诸如合并的致密双星系统、低质量X射线双星中的中子星、恒星坍缩和双星等源都是可能的探测对象。最有希望的引力波探测器设计是使用相距很远的测试质量,并将其作为悬挂物自由悬挂在地球上或太空中的无阻力飞行器中。本综述的主要主题是讨论在世界各地运行的各种长基线系统中使用的机械和光学原理- LIGO(美国)、Virgo(意大利/法国)、TAMA 300和LCGT(日本)以及GEO 600(德国/英国)。- 在LISA中,提出了一种星载干涉仪。除了强调迄今为止取得的天体物理学成果外,还将讨论对目前这一代地面探测器最近进行的科学研究的审查。展望未来,LIGO(Advanced LIGO)、Virgo(Advanced Virgo)、LCGT和GEO 600(GEO-HF)的重大升级将在未来几年内完成,这将创建一个探测器网络,其探测引力波所需的灵敏度将大幅提高。除此之外,还将讨论未来可能的“第三代”引力波探测器的概念和设计,如爱因斯坦望远镜(ET)。

英文摘要:

Significant progress has been made in recent years on the development of gravitational wave detectors. Sources such as coalescing compact binary systems, neutron stars in low-mass X-ray binaries, stellar collapses and pulsars are all possible candidates for detection. The most promising design of gravitational wave detector uses test masses a long distance apart and freely suspended as pendulums on Earth or in drag-free craft in space. The main theme of this review is a discussion of the mechanical and optical principles used in the various long baseline systems in operation around the world - LIGO (USA), Virgo (Italy/France), TAMA300 and LCGT (Japan), and GEO600 (Germany/U.K.) - and in LISA, a proposed space-borne interferometer. A review of recent science runs from the current generation of ground-based detectors will be discussed, in addition to highlighting the astrophysical results gained thus far. Looking to the future, the major upgrades to LIGO (Advanced LIGO), Virgo (Advanced Virgo), LCGT and GEO600 (GEO-HF) will be completed over the coming years, which will create a network of detectors with significantly improved sensitivity required to detect gravitational waves. Beyond this, the concept and design of possible future "third generation" gravitational wave detectors, such as the Einstein Telescope (ET), will be discussed.
