We present a CMB map reconstructed from both WMAP and Planck datasets. Using recent statistical tools based on sparsity, we show that the Galactic barrier can be broken down, so that we can have a full sky high quality CMB map, for the first time. In addition, as a result of our novel approach, this high quality map is free of any significant thermal Sunyaev-Zel’Dovich effect contamination. Then, we revisit the different large-scale CMB anomalies considered as violations of its statistical isotropy or Gaussianity. Finally, we present a reconstruction of the primordial power spectrum from Planck data.
