Polarization of the cosmic microwave background radiation

Abstract

In re-ionized models, the measurement of polarization of CMBR can be a good criterion to narrow down the parameter space for cosmological models. A Vishniac-type effect in second order polarization over arc minute scales has been calculated. It has been shown that while the effect is very small (∼10−2 µK) for CDM models, it can be significant (∼0.3µK) for some isocurvature models.
