宇宙弦的尖端会发射出强烈的高频引力波（GW）束。由于这些光束，由振荡环的宇宙学网络产生的引力波的随机系综是强烈的非高斯分布，并且包括高于均方根引力波背景的偶尔的尖锐爆发。对于小至类似于 10(-13) 的 G mu 的弦张力，计划中的 GW 探测器 LIGO/VIRGO 和 LISA 可以检测到这些爆发。这里讨论的引力波爆发可能伴随着伽马射线爆发。
Cusps of cosmic strings emit strong beams of high-frequency gravitational waves (GW). As a consequence of these beams, the stochastic ensemble of gravitational waves generated by a cosmological network of oscillating loops is strongly non-Gaussian, and includes occasional sharp bursts that stand above the rms GW background. These bursts might be detectable by the planned GW detectors LIGO/VIRGO and LISA for string tensions as small as G mu similar to 10(-13). The GW bursts discussed here might be accompanied by gamma ray bursts.
