INTEGRATED SACHS–WOLFE EFFECT FOR GRAVITATIONAL RADIATION
Gravitational waves (GWs) are messengers carrying valuable information about their sources. For sources at cosmological distances, the waves will also contain the imprint left by the intervening matter. The situation is in close analogy with cosmic microwave photons, for which the large-scale structures the photons traverse contribute to the observed …
