PPT-Polarization in Interferometry

Rick Perley NRAOSocorro Recap and Plan Dave has shown you why determining the full polarization state of natural radiation is important In this lecture I describe how an interferometer determines the Stokes parameters for distant sources. The value of . reionization. fraction derived from CMB polarization measurements has decreased steadily since WMAP2003 (WMAP2005, WMAP2007, WMAP2011, and Planck 2015). The final word from Planck is not out yet , and whenever it is out, it will surely not be “a 100-sigma measurement” of . limits on . dark . energy. Jun. 17. 2011. Geena Kim. P. Hamilton, D.
