The Cold Spot could be an adiabatic perturbation on the surface of last scattering, in which case it is an over-density with comoving radius of the order of 1 Gpc. We assess the effect that living in a similar structure, without knowing it, has on our perception of the equation of state of Dark Energy. We find that structures of dimensions such that they could cause the Cold Spot on the CMB, affect the perceived equation of state of Dark Energy possibly up to ten percent.

  1. CMB sky for an off-center observer in a local void I: framework for forecasts

    astro-ph.CO 2019-08 conditional novelty 6.0 of 10

    An off-center observer in an LTB void would see off-diagonal CMB correlations; the paper develops a Fisher forecast framework and finds S/N > 10 for two illustrative void models with Planck.
