This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. The polarization of the CMB, discovered in 2002 by DASI, is now a dramatic success: in the 2015 Planck data release, there are seven observed peaks in the temperature (TT) power spectrum, six peaks in the temperature-polarization (TE) cross spectrum, and five peaks in the polarization (EE) spectrum. Here, this paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Cosmological parameters. 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. Let us know how this access is important for you. Cosmological parameters: Author(s): Ade, P.A.R. By A Lewis, D Munshi and et al. We find no evidence for any contribution from isocurvature perturbations or from cosmic defects. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. (2016) Planck 2015 results. From the Planck temperature and lensing data, for this cosmology we find a Hubble constant, H0= (67.8 +/- 0.9) km/s/Mpc, a matter density parameter Omega_m = 0.308 +/- 0.012 and a scalar spectral index with n_s = 0.968 +/- 0.006. When the additional informa- With the proposed assumptions: 1) The intended purpose of ‘lambda’ term can be understood and in future it can be relinquished. The spatial curvature of our Universe is found to be very close to zero, with | ΩK | < 0.005. Compared to the 2015 results, improved measurements of large-scale polarization allow the reionization optical depth to be measured with … The observational data we use in this work include the JLA sample of type Ia supernovae observation, the Planck 2015 distance priors of cosmic microwave background observation, the baryon acoustic oscillations measurements, and the direct measurement … Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision.

(We quote 68% errors on measured parameters and 95% limits on other parameters.) The standard big bang nucleosynthesis predictions for the helium and deuterium abundances for the best-fit Planck base ΛCDM cosmology are in excellent agreement with observations. Let us know how this access is important for you. In approximate percentage terms… Liddle (University of Edinburgh). Astronomy and Astrophysics, 594 (A13). 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 temperature and polarization power spectra are consistent with … Apart from these tensions, the base ΛCDM cosmology provides an excellent description of the Planck CMB observations and many other astrophysical data sets. These data are consistent with the six-parameter inflationary LCDM cosmology. Note that in this abstract we quote 68% confidence limits on measured parameters and 95% upper limits on other parameters. Planck 2015 Results: Cosmological Parameter Tables January 19, 2015 Abstract These tables summarize the results of Planck 2015 parameter estimation exploration results. In neither case do we find no evidence for new physics. Combining Planck data with other astrophysical data, including Type Ia supernovae, the equation of state of dark energy is constrained to w =-1.006 ± 0.045, consistent with the expected value for a cosmological constant. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. 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.

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. We find no evidence for any contribution from isocurvature perturbations or from cosmic defects. With four unified, simplified and workable assumptions, a number of useful cosmological formulae can be generated and the current Hubble parameter and current microwave back ground temperature can be fitted accurately. We also constraints on annihilating dark matter and on possible deviations from the standard recombination history. This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Lewis, A, Munshi, D and The Planck Collaboration, et al. The standard big bang nucleosynthesis predictions for the helium and deuterium abundances for the best-fit Planck base ΛCDM cosmology are in excellent agreement with observations. We also constraints on annihilating dark matter and on possible deviations from the standard recombination history. The sum of neutrino masses is constrained to â'mν < 0.23 eV. 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. These results are consistent with those from WMAP polarization measurements cleaned for dust emission using 353-GHz polarization maps from the High Frequency Instrument. The Planck results for base ΛCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. Introduction Since its first discovery by Penzias and Wilson (1965), observations of the cosmic Cosmological parameters | severely abridged - Subm. We find no evidence for any departure from base ΛCDM in the neutrino sector of the theory; for example, combining Planck observations with other astrophysical data we find Neff = 3.15 ± 0.23 for the effective number of relativistic degrees of freedom, consistent with the value Neff = 3.046 of the Standard Model of particle physics. The Planck 2015 cosmological parameters using both temperature and polarization data are in very good agreement with those from the 2013 release, but with significantly improved precision. Prediction of quantum perturbation is one of interesting features of inflationary scenario. From the Planck temperature data combined with Planck lensing, for this cosmology we find a Hubble constant, H0 = (67.8 ± 0.9) km s-1Mpc-1, a matter density parameter Ωm = 0.308 ± 0.012, and a tilted scalar spectral index with ns = 0.968 ± 0.006, consistent with the 2013 analysis. The addition of Planck polarization data leads to strong constraints on deviations from a purely adiabatic spectrum of fluctuations.
