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.
