Abstract

I will compare the results from the full Planck mission data which will be submitted at the end of January with the results that we published in 2013. I will focus particularly on tensions between Planck CMB measurements and other astrophysical data. Some tensions reported in 2013 have been resolved with improvements to the astrophysical data, but new tensions have emerged. Overall the simple 6 parameter ΛCDM cosmology continues to provide an excellent fit to the Planck temperature and polarisation data.
