CMB anisotropies and the ISW effect

    Two papers on arxiv today, http://arxiv.org/abs/1312.0025 and http://arxiv.org/abs/1312.0275, propose to resolve a large part of the CMB anisotropies suggested by WMAP and Planck based on the Integrated Sachs-Wolfe effect. The authorship appears independent, the former group is from India, and the latter from Spain, USA and Italy.

    Do you know what was thought to be the cause of the anisotropies prior to these papers?

    Possible explanations for the dipole modulation addressed by 1312.0275 have included gigantic voids, a topological defect remaining from a phase transition in the early universe, and quantum entanglement with a parallel universe before separation occurred during inflation. They invoked some rather ... exotic ... physics.
