Assuming the base-ΛCDM cosmology, the inferred (model-dependent) late-Universe parameters are: Hubble constant H₀ = (67.4 ± 0.5) km s⁻¹ Mpc⁻¹; matter density parameter Ωm = 0.315 ± 0.007; and matter fluctuation amplitude σ₈ = 0.811 ± 0.006. [616170]. 6-parameter CDM cosmology with a power-law spectrum of adiabatic scalar perturbations (denoted âbase CDMâ in this paper). Planck 2018 results. We find good consistency with the standard spatially-flat 6-parameter ΛCDM cosmology having a power-law spectrum of adiabatic scalar perturbations (denoted “base ΛCDM” in this paper), from polarization, temperature, and lensing, separately and in combination. Some results with additional data are produced by importance sampling. This project has received funding
This paper presents the cosmological legacy of Planck, which currently provides our strongest constraints on the parameters of the standard cosmological model and some of the tightest limits available on deviations from that model. 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 JA, and RES (Spain); Tekes, AoF, and CSC (Finland); DLR and MPG (Germany);

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^-1Mpc^-1, a matter density parameter Omega_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). https://resolver.caltech.edu/CaltechAUTHORS:20191002-090602025, https://doi.org/10.1051/0004-6361/201833910, School of Electronics and Computer Science.

Abstract. A combined analysis gives dark matter density Ω_ch² = 0.120 ± 0.001, baryon density Ω_bh² = 0.0224 ± 0.0001, scalar spectral index n_s = 0.965 ± 0.004, and optical depth τ = 0.054 ± 0.007 (in this abstract we quote 68% confidence regions on measured parameters and 95% on upper limits).

We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information from the temperature and polarization maps and the lensing reconstruction. 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. © 2020 ESO.

We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information from the temperature and polarization maps and the lensing reconstruction. 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. Built at the Cannes Mandelieu Space Center by Thales Alenia Space, and created as a medium-sized mission for ESA's Horizon 2000 long-term scientific programme, Planck was launched in May 2009. 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). XXX, YYY, etc encode the data combinations used. Also combining with Type Ia supernovae (SNe), the dark-energy equation of state parameter is measured to be w₀ = −1.03 ± 0.03, consistent with a cosmological constant. results from the PArthENoPE code, Cyril Pitrou for producing some results from

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. 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.
