论文摘要
从二进制中子星（BNS）聚结的重力波（GW）瞬变原则上可以受到重力透镜的影响，从而增加幅度和信噪比。我们估计了Ligo和Pirgo可分解的镜头BNS事件的速率，并发现它受到随机GW背景的当前未检测的约束。 Following closely the formalism we developed (10.1103/PhysRevLett.125.141102) in the context of binary black hole lensing, we show that at current sensitivities the fraction of BNS coalescences with lensing magnifications $μ> 1.02$ is less than $\sim 7\times 10^{-8}$ and therefore such events should not be expected in the near future.我们还对预计的未来敏感性做出了预测。
Gravitational wave (GW) transients from binary neutron star (BNS) coalescences can, in principle, be subject to gravitational lensing thereby increasing the amplitude and signal-to-noise ratio. We estimate the rate of lensed BNS events resolvable by LIGO and Virgo and find that it is constrained by the current non-detection of a stochastic GW background. Following closely the formalism we developed (10.1103/PhysRevLett.125.141102) in the context of binary black hole lensing, we show that at current sensitivities the fraction of BNS coalescences with lensing magnifications $μ> 1.02$ is less than $\sim 7\times 10^{-8}$ and therefore such events should not be expected in the near future. We also make predictions for projected future sensitivities.
