Cosmicflows-3: Cold Spot Repeller?
  The three-dimensional gravitational velocity field within z~0.1 has been
modeled with the Wiener filter methodology applied to the Cosmicflows-3
compilation of galaxy distances. The dominant features are a basin of
attraction and two basins of repulsion. The major basin of attraction is an
extension of the Shapley concentration of galaxies. One basin of repulsion, the
Dipole Repeller, is located near the anti-apex of the cosmic microwave
background dipole. The other basin of repulsion is in the proximate direction
toward the 'Cold Spot' irregularity in the cosmic microwave background. It has
been speculated that a vast void might contribute to the amplitude of the Cold
Spot from the integrated Sachs-Wolfe effect.
