| Abstract: |
The study of the Cosmic Microwave Background radiation (CMB) enters a
new era. Since precision measurements of the CMB temperature
anisotropies by the WMAP satellite experiment, the challenge is now to
extract informations from the polarization anisotropies, several
orders of magnitude fainter than the ones in temperature. As a
consequence of this weakness, contamination from polarized Galactic
emissions will limit the measurement of this signal, which constitutes a wealth
of information on the early-Universe physics. This review starts by
giving a brief introduction to CMB and its polarization physics, formalism and
on the benefits of its precision measurement for cosmology. We will
give the measurement status of CMB polarization and present the PLANCK experiment, designed to provide the best measurement of CMB
polarization in a near future. |
