Dark energy and the CMB cold spot

    Two papers went up today regarding infrared all sky surveys by WISE and 2MASS that affirm the CMB cold spot - http://arxiv.org/abs/1405.1555, A Supervoid Imprinting the Cold Spot in the Cosmic Microwave Background; http://arxiv.org/abs/1405.1566, Detection of a Supervoid Aligned with the Cold Spot of the Cosmic Microwave Background. The effect of large voids on dark energy models has been discussed in the literature for the last decade. Does this lend credence to papers like http://arxiv.org/abs/0712.0370, Local Void vs Dark Energy: Confrontation with WMAP and Type Ia Supernovae; a heavily cited paper that questions the need for dark energy?

    interesting articles, however I'm not familiar enough with the MV model to draw any connection

    The Lemaitre-Tolman-Bondi model is a central issue here, IMO.
