论文摘要
我们研究引力波在虫洞和正常物质物体上散射的特定特征。我们得出并求解GW能量传输方程，并表明散射信号与基本信号相同的频谱带。散射形成特定的长尾巴，总是伴随基本信号并具有通用形式。正常物质物体上的散射形成始终具有延迟特征的尾巴，而虫洞也会导致高级尾巴。此外，当尾巴中的总能量超过了$ 10^{3} $的因子时，虫洞可能会产生更强的效果。在这两种情况下，当平均幅度以$ h \ sim 1/\ sqrt {t+r/c} $为单位时，延迟的尾巴具有很长的活性。对于单个GW事件，回声尾部仅对平均振幅产生很小的贡献。但是，这种尾巴会随着事件而积聚，并且可以通过它们对随机GW背景产生的噪声的贡献来观察。
We study specific features of the scattering of gravitational waves on wormholes and normal matter objects. We derive and solve the GW energy transport equation and show that the scattered signal lies in the same frequency spectrum bands as the basic signal. The scattering forms specific long living tails which always accompany the basic signal and have a universal form. The scattering on normal matter objects forms tails which have always the retarding character, while wormholes lead to advanced tails as well. In addition, wormholes may produce considerably stronger effect, when the total energy in tails exceeds the energy of the incident wave by the factor up to $10^{3}$ . In both cases the retarding tails have a long living character when the mean amplitude behaves with time as $h\sim 1/\sqrt{t+R/c}$. For a single GW event the echo tails give only a tiny contribution to the mean amplitude. However such tails accumulate with events and may be observed by their contribution to the noise produced by the stochastic GW background.
