Title: Imaging cosmic polarization rotation
Authors: Contaldi, CR
Item Type: Journal Article
Abstract: We introduce a method to isolate the contribution of parity-violating modes to the peak constrained correlation function. This method can be used as a local estimate of polarization rotation. We test this method using simulations and by applying it to Planck maps [P. A. R. Ade et al., arXiv:1502.01589]. We obtain a constraint on the monopole of the polarization rotation angle α=0.31±0.23α=0.31±0.23.
