Recording gravity waves over the noise floor

Click For Summary
SUMMARY

The discussion focuses on the recording of gravitational waves, emphasizing that the amplitude of these waves is indeed below the thermal noise floor. Advanced noise reduction techniques were employed to ensure that the observed signals were distinguishable from the noise. The conversation also highlights the importance of referring to relevant publications for detailed methodologies, including specifics on sampling rates and bit depth used in the recording process.

I'm curious as to how the gravity waves were recorded given how small the amplitude of the wave was/is. Was it not below the thermal noise floor? Were noise removal techniques used, etc?

Also, what kind of sampling rate/bit depth was used?

Thanks

You probably mean gravitational waves. Gravity waves are water waves, for example.
As you can see in the publications, the noise was smaller than the observed signal, and a lot of effort was put into noise reduction.
All the other details are in the publications as well.
