Abstract

Our previous work [1] showed that if a primordial magnetic field (PMF) was present during photon decoupling and afterward, massive neutrinos affect all modes of the CMB. This is because of the compensation of anisotropic stress between the neutrinos and the PMF. In order to study the observability of this new effect, we need careful analysis of the passive mode [2] generated by the PMF. Here, we focus on the polarization of the CMB and study the observability of the finite neutrino mass effect.
