Planck 2018 lensing power-spectrum band powers (pink boxes) over the aggressive multipole range. By N. Aghanim, T. Ghosh, J. J. Bock, B. P. Crill, O. Doré, G ... We find good consistency between lensing constraints and the results from the Planck CMB power spectra within the ΛCDM model. The 6-parameter ΛCDM model continues to provide an excellent fit to the cosmic microwave background data at high and low redshift, describing the cosmological information in over a billion map pixels with just six parameters. Planck 2018 results. Compared to the 2015 results, improved measurements of large-scale polarization allow the reionization optical depth to be measured with … We also update the weaker constraint on τ from the joint TEB likelihood using the Low Frequency Instrument (LFI) channels, which was used in 2015 as part of our baseline analysis. The Planck Legacy Archive (PLA) contains all public products originating from the Planck mission. The Planck data, alone and in combination with other probes, provide stringent constraints on our models of the early Universe and the large-scale structure within which all astrophysical objects form and evolve.

With 18 peaks in the temperature and polarization angular power spectra constrained well, Planck measures five of the six parameters to better than 1% (simultaneously), with the best-determined parameter (θ*) now known to 0.03%. Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background (CMB) at microwave and infra-red frequencies, with high sensitivity and small angular resolution.The mission substantially improved upon observations made by the NASA Wilkinson Microwave Anisotropy Probe (WMAP). The 2015 Planck papers have been submitted to the A&A. I.

We find good consistency between lensing constraints and the results from the Planck CMB power spectra within the ΛCDMΛCDM model. This week, we released (most of) the final set of papers from the Planck collaboration — the long-awaited Planck 2018 results (which were originally meant to be the “Planck 2016 results”, but everything takes longer than you hope…), available on the ESA website as well as the arXiv. This paper describes the 2018 Planck CMB likelihoods, following a hybrid approach similar to the 2015 one, with different approximations at low and high multipoles, and implementing several methodological and analysis refinements. Compared to the 2015 results, improved measurements of large-scale polarization … With 18 peaks in the temperature and polarization angular power spectra constrained well, Planck measures five of the six parameters to better than 1 % (simultaneously), with the best-determined parameter (θ ∗) now known to 0.03 %. VI. We search for evidence of parity-violating physics in the Planck 2018 polarization data and report on a new measurement of the cosmic birefringence angle β.The previous measurements are limited by the systematic uncertainty in the absolute polarization angles of the Planck detectors. Planck 2018 results - IX. Our results provide a high-precision test for structure-formation scenarios, showing complete agreement with the basic picture of the ΛCDM cosmology regarding the statistics of the initial conditions, with cosmic structures arising from adiabatic, passive, Gaussian, and primordial seed perturbations.
