Multipole vectors: A new representation of the CMB sky and evidence for statistical anisotropy or non-Gaussianity at 2<=[script l]<=8
We propose a novel representation of cosmic microwave anisotropy maps, where each multipole order l is represented by l unit vectors pointing in directions on the sky and an overall magnitude. These 'multipole vectors and scalars' transform as vectors under rotations. Like the usual spheri...
