Question about gravitational waves, E modes

  1. May 16, 2015 #1
    Hi everybody, I have been reading about gravitational waves, but I don't get how the E modes work; in one place I read that they were created during the inflation time, but in other I read that they come from the recombination.
    Does it mean that they were produced almost when the Big Bang happened but I cam only see the ones from the recombination era?

    Thanks for reading.

    Do you mean E modes in the cosmic microwave background? Those are not gravitational waves.
