论文摘要
研究了具有任意传播方向的极低频率原始重力波对非对准引力透镜系统的影响。从真实天体物理透镜模型的角度来看，重力透镜系统中采用了单数等温球透镜模型。结果表明，在来自极低频率原始引力波的扰动下，重力透镜系统的时间延迟可能与理论模型的推论强烈偏离。这意味着强烈偏差的时间延迟可能是重力透镜系统上极低的原始引力波的烙印，这表明重力透镜系统可以用作长基线检测器来检测极低的频率原始引力波。
The effect of extremely low frequency primordial gravitational wave with arbitrary direction of propagation on a non-aligned gravitational lens system is investigated. From the point of view of real astrophysical lens model, singular isothermal sphere lens model is adopted in the gravitational lens system. The results show that, under the perturbation from extremely low frequency primordial gravitational wave, time delay in the gravitational lens system could strongly deviate from that deduced from theoretical model. This means that the strongly deviate time delay could be the imprint of extremely low frequency primordial gravitational wave on gravitational lens system, indicating that gravitational lens system could be used as a long baseline detector to detect extremely low frequency primordial gravitational wave.
