VIII. Abstract. Galactic astrophysics using polarized dust emission Coming later Planck 2018 results. IV. We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG).We compare estimates obtained from separable template-fitting, binned, and optimal modal bispectrum estimators, finding consistent values for the local, equilateral, and orthogonal bispectrum amplitudes. Before Planck… For this reason, the polarisation of the CMB retains information about the distribution of matter in the early Universe, and its pattern on the sky follows that of the tiny fluctuations observed in the temperature of the CMB.

The Cosmic Microwave Background - as seen by Planck. Cosmological parameters; Planck Collaboration (2018) The Universe has more matter and is expanding more slowly than we previously thought. XI. The results are fully consistent with the two previous Planck cosmological releases, but have smaller uncertainties thanks to improvements in the characterization of polarization at low and high multipoles. The oldest light in the universe is that of the cosmic microwave background (CMB). Mais le télescope Planck a aussi étudié la phase d’après le CMB, qu’on appelle « le fonds diffus infrarouge », « CIB » (Cosmic Infrared Background), provenant de la période de formation des grandes structures de l’Univers.
