Query: Global universe anisotropy probed by the alignment of structures in the
  cosmic microwave background   We question the global universe isotropy by probing the alignment of local
structures in the cosmic microwave background (CMB) radiation. The original
method proposed relies on a steerable wavelet decomposition of the CMB signal
on the sphere. The analysis of the first-year WMAP data identifies a mean
preferred plane with a normal direction close to the CMB dipole axis, and a
mean preferred direction in this plane, very close to the ecliptic poles axis.
Previous statistical anisotropy results are thereby synthesized, but further
analyses are still required to establish their origin.
