The Planck legacy - Reinforcing the case for a standard model of cosmology: $\Lambda$CDM

TL;DR

This paper reviews the Planck 2015 results, highlighting improved data calibration, temperature and polarization maps, cosmological parameters, and lensing potential, emphasizing the importance of foreground removal for future measurements.

Contribution

It provides a comprehensive overview of the Planck 2015 data release and discusses challenges for future satellite experiments in foreground removal.

Findings

Enhanced calibration of Planck data

First polarization maps in addition to temperature

Forecasts on Galactic foregrounds in polarization

Abstract

We present a brief review of the main results of the Planck 2015 release describing the new calibration of the data, showing the maps delivered in temperature and, for the first time, in polarization, the cosmological parameters and the lensing potential. In addition we present a forecast of the Galactic foregrounds in polarization. Future satellite experiments will have the challenge to remove the foregrounds with great accuracy to be able to measure a tensor-to-scalar ratio of less than 0.01.
