Ellipsoidal Universe Induces Large Scale CMB Polarization
Abstract
We calculate 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 Tpol/ T0 0.53 10-6 quite close to the average level of polarization detected by the Wilkinson Microwave Anisotropy Probe.
