Mapping the ionizing sources with CMB polarization measurements

Astrophysics 2007-05-23 v1

Abstract

We show that the delay of structure formation from WMAP3 can not fully account for the reduction of electron optical depth from WMAP1 to WMAP3 when the radiative transfer effects and feedback mechanisms are took into account in computing the reionization history of the Universe. As the ultimate limit in constraining the reionizatin history of the Universe with Planck will be placed by the our understanding of systematic effects and foregrounds removal, we discuss also these aspects.
