论文摘要
最近发现从Blazar TXS 0506+056发射可能中微子的发射是与天体物理源相关的第一个高能源中微子，这使得这种特殊类型的活性星系有望有希望的中微子发射器。检测到中微子排放的两个不同发作的事实大约3年，这一事实表明发射可能是周期性的。由于二进制合并接近的喷气液裂动，预计超级二进制黑洞系统会发生周期性排放。在这里，我们表明，如果TXS 0506+056是二进制来源，那么下一个中微子耀斑可能发生在2021年底之前。我们得出了二进制特性，该二进制特性将导致LISA从该系统中检测到重力波。我们的结果首次量化了TXS 0506+056示例的这些相关性的时间尺度，为此类来源的中微子和重力波签名提供了明确的预测。
The recent detection of possible neutrino emission from the blazar TXS 0506+056 was the first high-energy neutrino associated with an astrophysical source, making this special type of active galaxies promising neutrino emitters. The fact that two distinct episodes of neutrino emission were detected with a separation of around 3 years suggests that emission could be periodic. Periodic emission is expected from supermassive binary black hole systems due to jet precession close to the binary's merger. Here we show that if TXS 0506+056 is a binary source then the next neutrino flare could occur before the end of 2021. We derive the binary properties that would lead to the detection of gravitational waves from this system by LISA. Our results for the first time quantify the time scale of these correlations for the example of TXS 0506+056, providing clear predictions for both the neutrino and gravitational-wave signatures of such sources.
