中文摘要:
      激光干涉引力波观察台(LIGO)是世界卓越的干涉型引力波探测设备.最初的LIGO探测器已经超出了设计的灵敏度,能够用来探测相距大约40 Mpc的双中子星的合并信号,探测信噪比等于8.当探测器还没被建造时,LIGO科研团队主要和Virgo团队合作,探究了大量天体物理学方面的上限.LIGO目前已经步入了先进探测的新领域,拥有升级版的先进LIGO干涉型探测器.LIGO实验室也和众多印度研究中心合作,在印度建立了一个先进的LIGO干涉仪.从而LIGO探测网络扩展了,拥有3个远距分散的干涉仪在单一网络中运行.
英文摘要:
      The Laser Interferometric Gravitational Wave Observatory (LIGO) is the preeminent interferometric gravitational wave detector facility in the world. The initial LIGO detectors exceeded their design sensitivity and were able to search for signals from the coalescence and merger of compact neutron star binaries to a distance of ~40 Mpc (at SNR=8) for optimally oriented systems. While no detections were made, the LIGO Scientific Collaboration, mostly working jointly with the Virgo Collaboration, published a number of upper limits of astrophysical interest. LIGO is now poised to open the Era of Advanced Detectors with the commissioning of an upgraded Advanced LIGO interferometric detector. LIGO Laboratory is also collaborating with several Indian research centers to site an identical Advanced LIGO interferometer in that country, thereby expanding the LIGO detector network to three widely separated interferometers that will operate as a single network.
