Modeling parity-violating spectra in Galactic dust polarization with filaments and its applications to cosmic birefringence searches
The detection of rotation of linearly polarized cosmic microwave background photons, which is called cosmic birefringence, may suggest new parity-violating physics. However, scattering by dust can also mimic this same effect. In this paper, the authors extends a pre-existing dust filament model to compute this effect to make a forecast for future CMB experiments and assess the effect of this dust on present isotropic measurements of cosmic birefringence.
