We generalize the predictions for the cosmic microwave background (CMB) anisotropy patterns arising in Bianchi type VIIh universes to include a dark energy component. We consider these models in light of the result of Jaffe and collaborators in which a correlation was found on large angular scales between the WMAP data and the anisotropy structure in a low-density Bianchi universe. We find that by including a term ΩΛ > 0, the same best-fit anisotropy pattern is reproduced by several… Expand
