Cosmological results from Planck 2015

Abstract

Planck is an ESA satellite aimed at the observation of the Cosmic Microwave Background. This year we released the second round of cosmological results based on full mission data (~30+ months of observation) both in temperature and, for the first time, in polarization. In this talk, I will review a few of the most interesting cosmological results of this year release and highlight the power of polarization data to constrain possible extentions of the LCDM model. Finally, I will present some of the on-going work aimed at assessing the agreement between the WMAP and Planck results.
