abstract

In this work we consider non-zero circular polarization for the CMB radiation as a result of new interactions. We then rewrite the Boltzmann equations for the Stokes parameters $Q$, $U$ and $V$ and show that the circular polarization can generate the B-mode polarization even if no tensor perturbations are present.

Discussion (0). Continue with ORCID to comment.

    Compton scattering off partially polarized electrons can generate B-mode polarization from scalar density perturbations, with an amplitude proportional to the square of the electron polarization asymmetry.
