Ellipsoidal Universe Can Solve The CMB Quadrupole Problem
Published 12 Jun 2006 in gr-qc, hep-ph, and hep-th | (0606266v2)
Abstract: The recent three-year WMAP data have confirmed the anomaly concerning the low quadrupole amplitude compared to the best-fit \Lambda CDM prediction. We show that, allowing the large-scale spatial geometry of our universe to be plane-symmetric with eccentricity at decoupling or order 10{-2}, the quadrupole amplitude can be drastically reduced without affecting higher multipoles of the angular power spectrum of the temperature anisotropy.
