The nonlinear extension of this effect is known as the Rees-Sciama effect, and it gives rise to a namesake "plateau" at large-angular scales, followed by two acoustic peaks. The late-time version of it arises due to isocurvature and dark energy which generates potential wells and hills – and along with the early-time version due to primordial radiation, it comprises the integrated form of this effect. The ordinary form is simply the effect of a potential at the surface of last scattering. Responsible for the ripples observed by the COBE satellite, FTP, name this effect
