本文介绍了搜索的结果，从先进的LIGO和先进的处女座的第三次观测运行的数据中的通用短持续时间的引力波瞬变。搜索的目标是24-4096 Hz频带中持续时间为毫秒到几秒的瞬态，而不对输入信号的方向、极化或形态进行假设。引力波从紧凑的二进制聚结已被确定的其他有针对性的分析检测，但没有统计上显着的证据，其他引力波爆发被发现。这些包括更新的上限源率密度作为信号的特征频率的函数，这是大约一个数量级比以前的上限。这种搜索对从10 kpc的距离以1070 Hz的引力波辐射低至10[]-10[/] M[] c []2[/]的源很敏感，在每世纪一次的误报率下，探测效率为50%。这种搜索的敏感性，两个合理的天体物理学来源估计：中子星星f模式，这可能是由脉冲星毛刺，以及选定的核心塌陷超新星模型。
This paper presents the results of a search for generic short-duration gravitational-wave transients in data from the third observing run of Advanced LIGO and Advanced Virgo. Transients with durations of milliseconds to a few seconds in the 24-4096 Hz frequency band are targeted by the search, with no assumptions made regarding the incoming signal direction, polarization, or morphology. Gravitational waves from compact binary coalescences that have been identified by other targeted analyses are detected, but no statistically significant evidence for other gravitational wave bursts is found. Sensitivities to a variety of signals are presented. These include updated upper limits on the source rate density as a function of the characteristic frequency of the signal, which are roughly an order of magnitude better than previous upper limits. This search is sensitive to sources radiating as little as ∼10[SUP]-10[/SUP] M[SUB]⊙[/SUB]c[SUP]2[/SUP] in gravitational waves at ∼70 Hz from a distance of 10 kpc, with 50% detection efficiency at a false alarm rate of one per century. The sensitivity of this search to two plausible astrophysical sources is estimated: neutron star f modes, which may be excited by pulsar glitches, as well as selected core-collapse supernova models.
