Does ns depend on the wavelength? Isotropy and statistics V. Legacy Power Spectra and Likelihoods Planck 2018 results. … temperature (Aylor et al. 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. PlanckInflation2016˙driver c ESO 2019 October 8, 2019 Planck 2018 results. In correlated, mixed adiabatic and isocurvature models, the non-adiabatic contribution to the observed CMB temperature variance is constrained to 1.3%, 1.7%, and 1.7% at 95% CL for cold dark matter, neutrino density, and neutrino velocity, respectively. Does ns depend on the wavelength? A complementary analysis also finds no evidence for theoretically motivated parameterized features in the Planck power spectra.

I. Overview and the cosmological legacy of Planck Planck Collaboration, et.al., astro-ph. The Universe is found to be consistent with spatial flatness with a precision of 0.4% at 95% CL by combining Planck with a compilation of baryon acoustic oscillation data. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. The Planck 95% CL upper limit on the tensor-to-scalar ratio, r0.002 < 0.10, is further tightened by combining with the BICEP2/Keck Array BK15 data to obtain r0.002 < 0.056. Planck 2015 results.

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). X. XI. We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. Toggle navigation emion.io. The polarization data also provide improved constraints on inflationary models that predict a small statistically anisotropic quadrupolar modulation of the primordial fluctuations. We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Italiano; English; 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 obtain a Thomson optical depth τ = 0.058 ± 0.012 for … XII.

Constraints on primordial non-Gaussianity; Planck 2018 results. Polarized dust foregrounds Planck Collaboration, et.al., astro-ph. VII. 1 … Bond, J. Borrill, F.R. 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 present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the Cosmic Microwave Background anisotropies provided by the Planck satellite. 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 2018 Planck papers have been submitted to the A&A. PDF | On Sep 1, 2020, Y. Akrami and others published Planck 2018 results: IX. Isotropy and Statistics of the CMB” by the Planck Collaboration is published in Astronomy & Astrophysics. Planck; Collaboration • Y. Akrami (Leiden U. and ; Inst. Three different methods for the non-parametric reconstruction of the primordial power spectrum consistently confirm a pure power law in the range of comoving scales 0.005 Mpc-1 ≲ k ≲ 0.2 Mpc-1. Luke Hart, Jens Chluba, Updated fundamental constant constraints from Planck 2018 data and possible relations to the Hubble tension, Monthly Notices of the Royal Astronomical Society, Volume 493, Issue 3, April 2020, Pages 3255–3263, https://doi.org/10.1093/mnras/staa412. The prior was set to 20 < H0 < 100, slightly affecting the lower end of posterior. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative They are based on Planck HFI data and Planck lensing, as well as additional non-CMB data as detailed in the main parameter papers.
