<i>Planck</i> intermediate results [electronic resource] : XLIX. Parity-violation constraints from polarization data.
Parity-violating extensions of the standard electromagnetic theory cause in vacuo rotation of the plane of polarization of propagating photons. This effect, also known as cosmic birefringence, has an impact on the cosmic microwave background (CMB) anisotropy angular power spectra, producing non-vani...
