Statistical anisotropy in CMB spectral distortions
Measurements of the cosmic microwave background (CMB) spectral y-distortion anisotropy offer a test for the statistical isotropy of the primordial density perturbations on 0.01≲kMpc≲1. We compute the 1-point ensemble averages of the y-distortion anisotropies which vanish for the statistically isotro...
