论文摘要
审查和更新了由一对紧凑物体构成的超新星，磁铁和合并的随机引力背景。到目前为止，由两个黑洞组成的系统合并主导了背景信号，其幅度在10-100 Hz范围内超过了计划中的爱因斯坦激光干涉仪（ET）的灵敏度。 Ligo-Virgo协作估计的25 Hz的背景信号基于可用的合并检测数据，与当前的理论预测非常吻合。
The stochastic gravitational wave background produced by supernovas, magnetars and merger of binaries constituted by a pair of compact objects is reviewed and updated. The merger of systems composed by two black holes dominates by far the background signal, whose amplitude in the range 10-100 Hz is above the sensitivity of the planned Einstein laser interferometer (ET). The background signal at 25 Hz estimated by the LIGO-VIRGO collaboration, based on the available merger detection data, is in good agreement with the present theoretical predictions.
