On the large-scale cosmic microwave background polarization

Show Summary Details


We discuss the large-scale polarization of the cosmic microwave background induced by the anisotropy of the spatial geometry of our Universe. Assuming an eccentricity at decoupling of about 0.64 × 10−2, we find an average large-scale polarization ΔTpol/T0= (0.5–1.0) × 10−6. We suggest that the forthcoming polarization data at large scales from Planck will be able to discriminate between our proposal and the generally accepted re-ionization scenario.
