我们讨论了接收来自银河系外情报机构的无线电信号的可能性，大约在我们观察到银河系中的双中子星合并的时候。对二元参数的高进动测量将使它们能够在自己观测到合并信号之前104年发送信号∼。使用SKA，我们可以接收∼104bit的数据，这些数据是从40MPC传输的，输出功率为∼1TW。我们还讨论了GW170817的相关主题，并提到了未来引力波探测器在这一传输方案中的潜在作用。
We discuss the possibility of receiving a radio signal from extra-Galactic intelligence, around the time when we observe a binary neutron star merger in their galaxy. High-precession measurements of the binary parameters would allow them to send the signal ∼104 years before they themselves observe the merger signal. Using the SKA, we might receive ∼104 bits of data, transmitted from 40 Mpc away with an output power of ∼1TW. We also discuss related topics for GW170817 and mention potential roles of future gravitational wave detectors in relation to this transmission scheme.
