摘要
来自中子星并合的引力波编码了极端密度下核物质的信息，这是实验室实验无法触及的。晚期旋进受潮汐影响，而潮汐依赖于中子星状态方程。中子星并合通常预期会产生快速旋转的 remnant 中子星并发射引力波。这些将提供关于并合后极热环境的线索。核物质在引力波中的这一特征在2-4 kHz频带包含最多信息，而该频带处于当前探测器最灵敏波段之外。我们提出了中子星极端物质观测台（NEMO）的设计概念和科学依据：一种为利用并合中子星研究核物理而优化的引力波干涉仪。该概念采用高循环激光功率、量子压缩以及专门设计的探测器拓扑，以实现探测核物质所需的高频灵敏度。在1 kHz以上，所提出的应变灵敏度可与完整第三代探测器相媲美，而成本仅为其一小部分。这样的灵敏度将并合后 remnant 的探测事件率从两台A+探测器时约每数十年一次改变为每年数次，并可能首次实现超新星、孤立中子星及其他奇异天体的引力波观测。
