| contents | Polarization in the Cosmic Microwave Background James G. Bartlett Física, Astronomía y Matemáticas CMB observations Cosmic microwave background theory Cosmic microwave background (CMB) studies underpin our understanding of the universe and its history.Until recently, we have relied principally on CMB temperature observations to build our standard cosmologicalmodel, but today the field forges ahead into its next frontier CMB polarization anistropy. Polarization measurementswill furnish fresh and independent information on the primordial density perturbations and cosmologicalparameters, and they offer the exciting potential to detect primordial gravity waves, constrain dark energy andmeasure the neutrino mass scale. I review the science and longterm goals of CMB polarization measurementsand discuss current results and future observational projects. A vigorous program of groundbased, suborbitaland spacebased (e.g., WMAP and Planck [2008]) experiments is guiding us towards a future space missiondedicated to high precision polarization measurements. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436604 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4A Vol.36 |
