Description
The measure of the cosmic microwave background (CMB) anisotropies is a powerful tool to improve our understanding of the universe and of its evolution. Launched in May 2009, the Planck satellite is a third-generation mission aiming at the unprecedented measurement of these anisotropies (both in temperature and polarisation). In this talk, I will present the latest Planck release, which supplement the 2013 nominal mission temperature-only results with full mission temperature and polarisation data. The first part of the talk will briefly introduce the mission and important aspects of the (polarisation) data processing. In the second part of the presentation, I will describe some of the new products released by the collaboration and focus on polarisation-related results, such as the improved constraints on the cosmological paramters or the Planck/BICEP2 joint analysis for the primordial B-modes.
