Recording gravity waves over the noise floor

  1. Feb 22, 2016 #1
    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.
