# [PEM17-06] Confirmation of the proposal of five sets of binary of super massive black holes in the central region of our Galaxy

Keywords:Black Hole Binary, Galaxy Center, Decameter Radio Wave

The present studies are purposed to make rigorous confirmation of the approach of the present research work by giving proof for the following three subjects of questions.

Those are 1) to confirm the significance of the side bands of spectra as signature of the orbital motion of the black hole binary, 2) to find one to one correspondence between appearance of the Galaxy center and occurrence of FFT codes that verify the existence of BH binaries, and 3) to find identity between FFT results of observations and results of FFT of the simulation model that is constructed being based on observation periods.

The results of the works for subject 1),have indicated that there is clear difference between the observed FFT results which are characterized by many series of sidebands and the random array of noise spectra. The results of the works for subject 2), indicated that the FFT codes from the observed data appear even in the periods when the center of Galaxy center is not observable. For this confusing situation, however, the occurrence of the mirage effects due to earth surface and ionosphere reflections of the decameter radio waves is verified. By the simulation work of the subject 3) it is confirmed that FFT results for the constructed model of the 5 BH binary systems with deduced periods show good coincidence with the results of FFT for the observed data. We can, therefore, conclude that our approach to propose the BH binary systems in the center part of our Galaxy is not erroneous
