"Planck 2015 observations of CMB temperature and polarisation anisotropies: implications for cosmology" by Dr. Massimiliano Lattanzi (Università di Ferrara and INFN Ferrara)
Abstract: The Planck satellite has observed the millimetre and sub-millimetre sky, in both temperature and polarisation, continuously for 50 months between 2009 and 2013. A first release of cosmology products, based on data acquired during 15 months of observations, took place in early 2013. In February 2015, the Planck collaboration released cosmology products based on data from the full 50 months of observations. In my talk, after a brief introduction describing the Planck satellite, its scientific payload and the 2015 data products, I will present results on the cosmological parameters based on the full mission temperature and polarization data. I will first discuss consistency of the data with the six-parameter inflationary LCDM cosmology, and then turn to extensions of the standard cosmological model, including implications for neutrino physics and inflationary models.
