论文摘要
使用多频观测，从Blazar MRK 〜501的无线电射线到伽马射线，我们使用抢劫和Lomb-Scargle算法构建了相应的光曲线和构建的周期图。还使用功率密度谱和降解功能分析研究了长期可变性。使用软件vartools， 我们还计算了方差分析，盒子最高方块和离散的傅立叶变换。这些技术的结果显示出可观的周期性<〜229 d。这与光谱中的粉红色噪声结合了结果，使我们提出了周期性是通过二级超大型二进制二进制黑洞产生的，绕着MRK 〜501中央发动机内部的主要发动机绕过。我们使用Jacobi椭圆函数构建了这种现象的相对论黯然失色的模型，发现在所有研究的波段中，发现每〜224 d发生的周期性相对论日食。这意味着发射的引力波的频率略高于0.1 MHz，远高于即将到来的LISA空间基于空间的干涉仪的操作范围，因此，这些引力波必须被视为未来LISA观察结果的主要科学目标。
Using multifrequency observations, from radio to gamma-rays of the blazar Mrk~501, we constructed their corresponding light curves and built periodograms using RobPer and Lomb-Scargle algorithms. Long-term variability was also studied using the power density spectrum and the detrended function analysis. Using the software VARTOOLS, we also computed the analysis of variance, box-least squares and discrete fourier transform. The result of these techniques showed an achromatic periodicity <~ 229 d. This, combined with the result of pink-color noise in the spectra, led us to propose that the periodicity was produced via a secondary eclipsing supermassive binary black hole orbiting the primary one locked inside the central engine of Mrk~501. We built a relativistic eclipsing model of this phenomenon using Jacobi elliptical functions, finding a periodic relativistic eclipse occurring every ~ 224 d in all the studied wavebands. This implies that the frequency of the emitted gravitational waves falls slightly above 0.1 mHz, well within the operational range of the upcoming LISA space-based interferometer, and as such, these gravitational waves must be considered as a prime science target for future LISA observations.
