Cosmology with Planck's Observations of the Cosmic Microwave Background

The Planck satellite was launched in 2009 and mapped the full sky in nine bands from 30 to 857 GHz, and has produced the most accurate to-date full sky maps of the temperature and polarization of the cosmic microwave background. The measurements are consistent to high precision with a spatially flat universe dominated by cold dark matter and a cosmological constant. The Planck data are consistent with single-field inflationary models. Planck's unprecedented characterization of polarized Galactic foreground emission has important implications for current and future sub-orbital measurements of the CMB, particularly as revealed by a joint analysis of Planck and BICEP2/Keck array data.
