AI 中文总结
本研究在LIGO-Virgo O3运行期间，对IceCube探测到的高能中微子相关引力波开展无模型定向搜寻，未发现显著引力波信号，同时设定了不同发射模型下引力波源的距离下限。
AI 中文摘要
我们搜寻在高级LIGO、高级Virgo和KAGRA的第三观测运行（O3）期间，由IceCube中微子天文台探测到的高能中微子相关的一般引力波瞬变。我们开展了无模型的定向搜寻，该搜寻对弱于实时报告或引力波瞬变目录中报告的引力波信号敏感，因此能够发现典型中微子后续搜寻所遗漏的符合事件。我们未发现具有统计显著性的引力波信号，并针对不同发射模型设定了可能引力波源的距离下限。
英文摘要
We search for generic gravitational-wave transients associated with high-energy neutrinos detected by the IceCube Neutrino Observatory during the third Observing Run (O3) of Advanced LIGO, Advanced Virgo, and KAGRA. We perform an unmodeled, targeted search, which is sensitive to gravitational-wave signals weaker than those reported in real time or in the gravitional-wave transient catalog, and can thus uncover coincidences missed by typical neutrino follow-up searches. We find no statistically significant gravitational-wave signal and set lower bounds on the distance of possible gravitational-wave sources for different emission models.
