Analyzing the records of gravitational observatories of the LIGO project we have found a specific asymmetry in the time domain, inherent only to the signals of their gravitational detectors. Its comparison with various periodic signals, Gaussian and non-Gaussian noises made it possible to draw a preliminary conclusion that the noise of gravitational detectors is a unique mixture of signals. We have developed our own system of filtering gravitational signals, which uses only linear time-invariant elements. All processing is performed exclusively in the time domain. Detection and recognition of gravitational wave signals were carried out using a specialized Pearson correlation analyzer. It has been revealed that the detectors’ noises include a significant (– 6 dB) component inherent to the reliably detected gravitational waves. This result allows one to reasonably assume that the gravitational noise is largely due to the merging processes of massive astronomical objects. Since the specific noise signal is registered by detectors continuously, the field of gravitational oscillations of sub-kilohertz range can be considered as detected. A method of analysis has been developed to estimate the contribution of the gravitational noise component to the total signal energy. Its advantage can be considered a low requirement for computing power: signal processing is provided in real-time using any PC. With the help of the proposed method, it will be possible not only to begin the radio-frequency estimation of the magnitude of gravitational disturbances, which follows from the recent publications but also, possibly, to construct a map of the gravitational noise of the sky. The hyperlinks to the data files we have been working with, also as the result files are in the paper. We also can provide the source code of our program upon a reasonable request.

Comment: Good day, dear readers!

We are pleased to present the working version of the analyzer program that we developed, with the help of which we obtained the results published here. A brief instruction on how to use the program is inside the archive file.
The file size is 23M:
We hope that the program will be useful for everyone interested in the issues covered in our article.
