SACHS-WOLFE EFFECT IN PERTURBED BIANCHI TYPE I UNIVERSE
In the framework of the C-gauge condition for the perturbed variables and the linear approximation for the anisotropy of the spacetime, we studied the formulae for the Sachs-Wolfe effect in dust filled and perturbed Bianchi type I universe model. The results were compared with those of the flat Friedmann model.
