Abstract
Analyzing the records of Advanced LIGO and Virgo gravitational observatories, we found a specific time-domain asymmetry, inherent only to the signals of their gravitational detectors. Experiments with different periodic signals, Gaussian and non-Gaussian noises made it possible to conclude that the noise of gravitational detectors is an unusual mixture of signals. The gravitational-wave signals have been detected and recognized using a specialized Pearson correlation analyzer. It turned out that the detector signals include a significant (–6 dB) component, which has the properties of records of reliably recognized gravitational waves. This allows one to argue that the gravitational noise is largely due to the processes of merging astronomical objects. Since the specific signal is registered by the detectors continuously, the field of gravitational oscillations of the sub-kilohertz band can be considered as detected. A method of analysis has also been developed to estimate the contribution of the gravitational noise component to the total signal energy. With its help it will be possible not only to pass to the radio-frequency estimation of the magnitude of gravitational disturbances but also, possibly, to construct a map of the gravitational noise of the sky.
