Abstract

Aims. A new method of determining the parameters of close binary systems of supermassive black holes (SMBHs) and the level of gravitational waves (GWs) on the Earth’s surface are proposed.Methods. Data are presented from long-term monitoring of possibly the most powerful emitter in the Universe, S 0528+134, at five frequencies in the radio range from 4.8 GHz to 37 GHz, obtained by the RT-22 radio telescope of the Radio Astronomy Laboratory CrAO in Simeiz, the RT-26 radio telescope at Michigan Observatory, and the 40 m radio telescope of the Owens Valley Radio Observatory.Results. The dynamics of powerful flares that have occurred in the object since its discovery in a sky survey in 1970 were considered. The main physical characteristics of binary SMBHs located in the central regions of the system were obtained. These data were used to find the masses of the SMBH companions, the parameters of their orbits, the energy reserve of the system, and the lifetime of the object before the SMBHs’ merger. The level of GWs on the Earth’s surface was determined and the possibility of their detection by International Pulsar Timing Array (IPTA) GW detectors was considered.

Blazar S 0528+134 可能是宇宙中最强大的发射器,包括引力波范围内的发射器
目的。提出了一种确定超大质量黑洞(SMBHs)近双星系统参数和地球表面引力波(GWs)水平的新方法。本文介绍了对可能是宇宙中最强大的发射体 S 0528+134 在 4.8 GHz 至 37 GHz 射电范围内五个频率上的长期监测数据,这些数据是由位于 Simeiz 的射电天文实验室 CrAO 的 RT-22 射电望远镜、密歇根天文台的 RT-26 射电望远镜和欧文斯山谷射电天文台的 40 米射电望远镜获得的。研究考虑了自 1970 年在巡天观测中发现该天体以来在其内部发生的强耀斑的动态。获得了位于该系统中心区域的双 SMBH 的主要物理特征。这些数据被用来计算 SMBH 伴星的质量、它们的轨道参数、系统的能量储备以及天体在 SMBH 合并前的寿命。确定了地球表面的全球变暖水平,并考虑了国际脉冲星定时阵列全球变暖探测器对其进行探测的可能性。
