Rotation of Linear Polarization Plane and Circular Polarization from Cosmological Pseudoscalar Fields
Fabio Finelli, Matteo Galaverni
We discuss the rotation of the linear polarization plane and the production of circular polarization generated by a pseudoscalar field acting as dark matter. We compute analyticall…
