Confidence intervals are derived from the MCMC samples, and assume the input likelihoods are exactly correct, so there is no quantification for systematic errors other than via the covariance, foreground and beam error models assumed in the likelihood codes. CMB and foreground extraction ⢠Planck 2018 results. We find no evidence for deviations from a purely power-law primordial spectrum, and combining with data from BAO, BICEP2, and Keck Array data, we place a limit on the tensor-to-scalar ratio r_(0.002) < 0.06. From the Planck temperature data combined with Planck lensing, for this cosmology we find a Hubble constant, H 0 = (67.8 ± 0.9) km s-1 Mpc-1, a matter density parameter Ω m = 0.308 ± 0.012, and a tilted scalar spectral index with n s = 0.968 ± 0.006, consistent with the 2013 analysis.

The Planck base-ΛCDM results are in good agreement with BAO, SNe, and some galaxy lensing observations, but in slight tension with the Dark Energy Survey’s combined-probe results including galaxy clustering (which prefers lower fluctuation amplitudes or matter density parameters), and in significant, 3.6σ, tension with local measurements of the Hubble constant (which prefer a higher value). The SDSS data consist of the BAO+RSD measurements, while the DES data consist of the cosmic shear, galaxy clustering, and galaxy-galaxy lensing data (i.e., 3×2pt).

Abstract. They include Planck HFI data in combination with LFI polarization, Planck lensing, as well as additional non-CMB data as detailed in the main parameter papers. Improved modelling of the small-scale polarization leads to more robust constraints on many parameters, with residual modelling uncertainties estimated to affect them only at the 0.5σ level. The scale factor is related to the observed redshift $${\displaystyle z}$$ of the light emitted at time $${\displaystyle t_{\mathrm {em} }}$$ by (2020) on cosmological parameters from the Planck Collaboration.1 Our ï¬rst results were presented inPlanck Collaboration XVI (2014, hereafterPCP13).

Combining with baryon acoustic oscillation (BAO) measurements (and considering single-parameter extensions) we constrain the effective extra relativistic degrees of freedom to be N_(eff) = 2.99 ± 0.17, in agreement with the Standard Model prediction N_(eff) = 3.046, and find that the neutrino mass is tightly constrained to ∑m_ν < 0.12 eV. We find that the Planck spectra at high multipoles (â â³ 40) are extremely well described by the standard spatially-flat six-parameter ÎCDM cosmology with a power-law spectrum of adiabatic scalar perturbations.

This value is consistent with a flat Universe for which Ω k =0, as expected by cosmological inflation. The expansion of the universe is parameterized by a dimensionless scale factor $${\displaystyle a=a(t)}$$ (with time $${\displaystyle t}$$ counted from the birth of the universe), defined relative to the present day, so $${\displaystyle a_{0}=a(t_{0})=1}$$; the usual convention in cosmology is that subscript 0 denotes present-day values, so $${\displaystyle t_{0}}$$ is the current age of the universe.

It was later renamed in honour of the German physicist Max Planck, who derived the formula for black-body radiation. The original usage referred to the parameters describing the global dynamics of the Universe, such as its expansion rate and curvature. 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 chain outputs contain some parameters that are not used, for example the beam mode ranges for all but the first mode (the beam modes are marginalised over anlaytically internally to the likelihood). Simple model extensions that can partially resolve these tensions are not favoured by the Planck data. The CMB spectra continue to prefer higher lensing amplitudes than predicted in base ΛCDM at over 2σ, which pulls some parameters that affect the lensing amplitude away from the ΛCDM model; however, this is not supported by the lensing reconstruction or (in models that also change the background geometry) BAO data.
