We consider the stochastic background of gravitational waves produced by a network of cosmic strings and assess their accessibility to current and planned gravitational wave detectors, as well as to big bang nucleosynthesis (BBN), cosmic microwave background (CMB), and pulsar timing constraints. We find that current data from interferometric gravitational wave detectors, such as Laser Interferometer Gravitational Wave Observatory (LIGO), are sensitive to areas of parameter space of cosmic string models complementary to those accessible to pulsar, BBN, and CMB bounds. Future more sensitive LIGO runs and interferometers such as Advanced LIGO and Laser Interferometer Space Antenna (LISA) will be able to explore substantial parts of the parameter space.
我们考虑了由宇宙弦网络产生的引力波的随机背景，并评估了当前和计划中的引力波探测器以及大爆炸核合成（BBN）、宇宙微波背景（CMB）和脉冲星计时限制对它们的探测能力。我们发现，来自干涉引力波探测器（如激光干涉引力波天文台（LIGO））的当前数据对宇宙弦模型参数空间中与脉冲星、BBN和CMB限制可及区域互补的区域敏感。未来更灵敏的LIGO运行以及诸如高级LIGO和激光干涉空间天线（LISA）等干涉仪将能够探索参数空间的大部分区域。
