论文摘要
我们表明，紧凑型锥形相对论喷气机的标准Blandford-Königl模型具有独特的特征：在给定的观察到的辐射频率下，接近射流的发射到达遥远观察者的位置，并在所有有限倾斜倾斜角的发射时在远处观察者的位置。我们表明，如果可以以高傅立叶和X射线时间序列之间的交叉相互关系，则可以使用该结果来确定喷气机是否是真正的对称性，对于具有一系列倾斜角度的中性星X射线二进制文件的样本，可以在高傅立叶频率下测量。我们还讨论了可用于在X射线二进制二进制中的高节奏时间序列数据中查找与标准模型的偏差的回声映射技术，并得出结论，可以合理地将其应用于某些系统。
We show that the standard Blandford-Königl model for compact conical relativistic jets has a peculiar feature: at a given observed frequency of radiation, the emission from the approaching jet arrives at the location of a distant observer at the same time as the emission from the counterjet for all finite inclination angles. We show that this result can be used to determine whether jets are genuinely symmetric, if the cross-coherence between radio and X-ray time series can be measured at high Fourier frequency for a sample of neutron star X-ray binaries with a range of inclination angles. We also discuss echo mapping techniques that can be used to look for deviations from the standard model in high cadence time series data on X-ray binary jets, and conclude that these can plausibly be applied to some systems.
