论文摘要

联合中子星的引力波编码在极密密度下的核物质信息，实验室实验无法访问。晚期的灵感受到潮汐的存在的影响，潮汐的存在取决于状态的中子星程。预计中子恒星合并通常会产生迅速旋转的残留中子星星，以发出引力波。这些将为我们非常热的合并后环境提供线索。重力波中核物质的这种特征包含2-4 kHz频带中的大多数信息，该信息在当前探测器的最敏感频带之外。我们介绍了中子恒星极端物质观测站（NEMO）的设计概念和科学案例：优化的重力波干涉仪，可与中子星合并。该概念使用高循环激光功率，量子挤压和专门设计的探测器拓扑，以实现使用引力波探测核物质所需的高频灵敏度。在一个kHz之上，提出的应变灵敏度与成本的一小部分相当。这种敏感性会改变预期的事件发生率，用于检测合并后残留物的大约几十年的大约一个A+检测器，每年有几个a+检测器，并有可能允许对超新星，孤立的中子星和其他埃克罗斯的首次引力波观测。

Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influenced by the presence of tides, which depend on the neutron star equation of state. Neutron star mergers are expected to often produce rapidly-rotating remnant neutron stars that emit gravitational waves. These will provide clues to the extremely hot post-merger environment. This signature of nuclear matter in gravitational waves contains most information in the 2-4 kHz frequency band, which is outside of the most sensitive band of current detectors. We present the design concept and science case for a neutron star extreme matter observatory (NEMO): a gravitational-wave interferometer optimized to study nuclear physics with merging neutron stars. The concept uses high circulating laser power, quantum squeezing and a detector topology specifically designed to achieve the high-frequency sensitivity necessary to probe nuclear matter using gravitational waves. Above one kHz, the proposed strain sensitivity is comparable to full third-generation detectors at a fraction of the cost. Such sensitivity changes expected event rates for detection of post-merger remnants from approximately one per few decades with two A+ detectors to a few per year, and potentially allows for the first gravitational-wave observations of supernovae, isolated neutron stars, and other exotica.
