Measuring Polarization in the Cosmic Microwave Background
@article{Seljak1997MeasuringPI, title={Measuring Polarization in the Cosmic Microwave Background}, author={Uros Seljak}, journal={The Astrophysical Journal}, year={1997}, volume={482}, pages={6 - 16} }
Polarization induced by cosmological scalar perturbations leads to a typical anisotropy pattern, which can best be analyzed in a Fourier domain. This allows one to distinguish a cosmological signal of polarization unambiguously from other foregrounds and systematics, as well as from polarization induced by nonscalar perturbations. The precision with which polarization and cross-correlation power spectra can be determined is limited by cosmic variance, noise, and foreground residuals. The choice…
