Brendan Crill (JPL) -- Cosmic Microwave Background and Galactic polarization with Planck and BICEP2/Keck Array data

Planck's full sky maps of polarized emission at 353 GHz provide an unprecedented look at polarized Galactic dust emission at high Galactic latitude. A joint analysis of 150 GHz polarized maps from BICEP2 and Keck Array at 150 GHz with Planck data at 353 GHz allows the removal of Galactic dust contamination from the measurement of lensed B-modes in the deep (57 nK deg) BICEP2/Keck maps as well as setting an upper limit on the primordial gravitational wave background from inflation. We present this analysis, describe prospects for polarized foreground cleaning of future suborbital measurements of CMB, and additionally describe Planck's measurements of the spatial correlation of polarized emission from synchrotron (using Planck 30 GHz) and dust at high galactic latitude, which complicates the removal of Galactic foregrounds at the foreground minimum of 70-100 GHz.
