XVI. Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background (CMB) at microwave and infra-red frequencies, with high sensitivity and small angular resolution.The mission substantially improved upon observations made by the NASA Wilkinson Microwave Anisotropy Probe (WMAP). 1 Introduction The tables are … We find that the Planck spectra at high multipoles (ℓ ≳ 40) are extremely well described by the standard spatially-flat six-parameter ΛCDM cosmology with a power-law spectrum of adiabatic scalar perturbations. At a March 21 NASA telephone news conference, scientists from the U.S. team participating in the European Space Agency’s Planck mission to map the cosmic microwave background (CMB) discussed Planck’s first cosmological results, including some surprising news.

Parameter chains are produced using CosmoMC, a sampling package available here. We present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the Cosmic Microwave Background anisotropies provided by the Planck satellite. This allows a reﬁnement of the CDM best-ﬁt solution with respect to previously-released results, and the construction of frequentist conﬁdence intervals using proﬁle like- lihoods. They include Planck data in combination with WMAP polarization, Planck lensing, and high-l CMB experiments, as well as additional non-CMB data as detailed in the main parameter papers. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. We provide results from MCMC exploration chains, as well as best fits, and sets of parameter tables. 1.
