我们回顾了新引力波天文台（NGO，a.k.a.）的预期科学性能。eLISA），这是欧洲航天局正在研究的一项使命，将于本世纪20年代初发射。eLISA将观测低频引力波天空（从0.1兆赫到1赫兹），探测和表征整个宇宙中各种各样的系统和事件，包括星系合并所带来的大质量黑洞的聚结;恒星质量黑洞和致密恒星进入银河系中央黑洞的螺旋;银河系中有数百万个超紧凑的双星，它们既分离又在进行质量转移;还有可能是不可预见的来源，比如来自早期宇宙的残余引力波辐射。eLISA的高信噪比测量将为宇宙的结构和历史提供新的见解，并将在其强场动力学机制中测试广义相对论。
We review the expected science performance of the New Gravitational-Wave Observatory (NGO, a.k.a. eLISA), a mission under study by the European Space Agency for launch in the early 2020s. eLISA will survey the low-frequency gravitational-wave sky (from 0.1 mHz to 1 Hz), detecting and characterizing a broad variety of systems and events throughout the Universe, including the coalescences of massive black holes brought together by galaxy mergers; the inspirals of stellar-mass black holes and compact stars into central galactic black holes; several millions of ultra-compact binaries, both detached and mass transferring, in the Galaxy; and possibly unforeseen sources such as the relic gravitational-wave radiation from the early Universe. eLISA's high signal-to-noise measurements will provide new insight into the structure and history of the Universe, and they will test general relativity in its strong-field dynamical regime.
