Development of studies of the Earth’s electromagnetic field in the range of gravitational wave radiation binary star systems

The process of development of theoretical and experimental studies of the relationship between terrestrial electromagnetism and gravitational-wave astrophysical processes is analyzed. It is shown that the developed and patented “Eigenoscopy” method allows one to represent a time series in the form of uncorrelated components- eigenvectors of the covariance matrix, built based on the results of databases of long-term monitoring of the Earth’s electromagnetic field. Using Eigenoscopy, incoherent components were identified, spectrally localized at the frequency of the axion-photon interaction. Signs of the gravitational wave nature of the detected components at the frequencies of GW radiation from the RDS are identified using the databases of the Earth’s electric field at the observation stations VlGU, Dusheti, Voeikovo, and Verkhnee Dubrovo. The prediction by Zeldovich Ya.B. was confirmed. and Novikova I.D., that for an EDS with a high eccentricity, GW radiation should be observed at high harmonics, in contrast to EDS with a low eccentricity, in which GW radiation is observed at the second harmonic.
