Phys. Rev. D 47, 409–415 (1993)Comparison of the Sachs-Wolfe effect for Gaussian and non-Gaussian fluctuationsReceived 18 June 1992; published in the issue dated 15 January 1993 A consequence of non-Gaussian perturbations on the Sachs-Wolfe effect is studied. For a particular power spectrum, predicted Sachs-Wolfe effects are calculated for two cases: a Gaussian (random phase) configuration and a specific kind of non-Gaussian configuration. We obtain the result that the Sachs-Wolfe effect for the latter case is smaller when each temperature fluctuation is properly normalized with respect to the corresponding mass fluctuation (δM/M)(R). The physical explanation and the generality of the result are discussed. © 1993 The American Physical Society URL:
