CMB Anisotropies Generated by Cosmic Voids and Great Attractors

A recent result, based on the potential approximation, concerning the effect of a nonstatic gravitational potential on the propagation of light, is used to study the influence of compensated and uncompensated non-linear structures on the cosmic microwave background radiation. We obtain the temperature profile as well as the deflection of the microwave photons produced by the cosmic voids and great attractors whose existence has recently been claimed in the literature.
