摘要

分析了近60年来活动星系核3C 273长期多频监测项目的数据。提出了一个从超大质量黑洞（SMBH）中寻找封闭双星系统（CBSs）参数的模型，包括对在光学和无线电范围内获得的观测数据序列的谐波分析。这项研究的目的是表明，在没有关于AGN的光学信息的情况下，只能使用无线电数据，并且可以获得关于物理物体的必要信息。关于blazar 3C 273的例子，获得了以下参数：同伴的质量；它们的轨道特性，例如轨道上的运动速度；系统动能的储备；以及其他。研究发现，AGN3C273可能是一个质量非常大的双星系统，处于接近合并的演化阶段。基于获得的参数，考虑了该系统的引力波特性、合并前的寿命以及使用引力波探测器可能观测到的3C 273。

A Close Binary Supermassive Black Hole Model for the Galaxy 3C 273

The data from the last 60 years on the programs of long-term multi-frequency monitoring of active galactic nucleus (AGN) 3C 273 were analyzed. A model is proposed for finding the parameters of close binary systems (CBSs) from supermassive black holes (SMBHs), including a harmonic analysis of observational data series obtained in the optical and radio ranges. The purpose of this research was to show that in the absence of optical information on AGNs, only radio data can be used and the necessary information on the physical objects can be obtained. Regarding the example of the blazar 3C 273, the following parameters were obtained: the masses of the companions; their orbital characteristics, such as the speeds of movement in orbits; the reserves of the kinetic energy of the system; and others. It was found that AGN 3C 273 can be a very massive binary system at the stage of evolution close to merging. Based on the obtained parameters, the characteristics of the gravitational waves (GWs) of this system, its lifetime before the merger, and the possible observation of 3C 273 using gravitational wave detectors were considered.
