It was established that the chirp signals (signals of merger of black holes) are absent in the data. This is proved by using a coherent filtering and also two-stage causal filtering. Soliton-like signals such as wavelet “Mexican hat” are found by filtering based on the Butterworth filter. These signals are different in polarity, and their spectra are quite different. Doubts about the authenticity of the detection of chirp signals, which announced on February 11, 2016, are justified by the results the conducted analysis.展开更多

The relative displacements of various points of the Earth are detected by GSA, these displacements are described as quasi-harmonic elliptical signals generated by gravitational waves, their amplitude ≈ 2.5 * 0<sup>?15</sup> m. It is found that these waves cause deformation (strain) of the order h ≈ 10<sup>?21</sup>. Pulsars are a natural source of periodic waves. The fact of confident registration of gravitational wave is confirmed by detection of quasi-harmonic signals in the frequency band near 6.023 Hz for 90 hours (confidence probability of detection is close to 1). It is found that a small part of the rotation energy of associated pulsar (ε ≈ 10<sup>?5</sup>) is expended on the radiation corresponding to the gravitational wave.展开更多
