Faraday rotation in CMB maps
Published online by Cambridge University Press: 12 October 2016
Abstract
WMAP CMB polarization maps have been used to detect a low signal of Faraday Rotation (FR). If this detection is not interpreted as simple noise, it could be produced:
at the last scattering surface (LSS) (z=1100), being primordial,
at Reionization (z=10),
in the Milky Way.
The second interpretation is favoured here. In this case magnetic fields at Reionization with peak values of the order of 10-8 G should produce this observational FR.
