1207.0734 (Fulvio Melia)

CMB Multipole Alignment in the R_h=ct Universe    [PDF]

Fulvio Melia
An analysis of the full cosmic microwave background (CMB) sky by the Wilkinson Microwave Anisotropy Probe (WMAP) has revealed that the two lowest cosmologically interesting multipoles, the quadrupole (l=2) and the octopole (l=3) moments of the temperature variations, are unexpectedly aligned with each other. In this paper, we demonstrate that, whereas this alignment constitutes a statistically significant anomaly in the standard model, it is statistically insignificant within the context of the R_h=ct Universe. The key physical ingredient responsible for this difference is the existence in the latter of a maximum fluctuation size at the time of recombination, which is absent in LCDM because of inflation.
