We present the first results of polarization measurements with the Low Frequency Instrument at large angular scales. We find no evidence for any departure from base Lambda CDM in the neutrino sector of the theory;for example, combining Planck observations with other astrophysical data we find N-eff = 3.15 +/- 0.23 for the effective number of relativistic degrees of freedom, consistent with the value N-eff = 3.046 of the Standard Model of particle physics. The Planck spectra at high multipoles are extremely well described by the standard spatially-flat six-parameter LCDM cosmology. Planck Collaboration, Ade, P. A. R., Aghanim, N., Arnaud, M., Ashdown, M., Aumont, J., et al. Particularly prominent are measurements of cosmic microwave background (CMB) anisotropies, with the highest precision observations being those of the Planck Satellite [1,2] which supersede the landmark WMAP results [3,4]. 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. 1 Isotropy and statistics of the CMB.

Astronomy & Astrophysics manuscript no. The European Space Agency's Planck satellite gathered data for over 4 years, and a series of 28 papers releasing the results and evaluating constraints on cosmological models have been recently released. Results of the Planck mission released in 2015 show the cosmological curvature parameter, Ω K, to be 0.000±0.005, consistent with a flat universe. 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. In this model Planck data determine the cosmological parameters to high precision. Planck 2015 results. These data are consistent with the six-parameter inflationary LCDM cosmology. Parametrizing the Universe Rapid advances in observational cosmology have led to the establishment of a precision cosmological model, with many of the key cosmological parameters determined to one or two significant figure accuracy.

Particularly prominent are measurements of … Abstract. Planck 2015 Results: Cosmological Parameter Name Tags January 16, 2015 This table summarises cosmological parameters used in the Planck chains. In neither case do we find no evidence for new physics. We show that these tensions cannot easily be resolved with simple modifications of the base ΛCDM cosmology. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. However, as in the 2013 analysis, the amplitude of the fluctuation spectrum is found to be higher than inferred from some analyses of rich cluster counts and weak gravitational lensing. This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) 594, A13, School of Electronics and Computer Science, Vollständige Autorenliste siehe Verlagsseite bzw. 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 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 find no evidence for any contribution from isocurvature perturbations or from cosmic defects. The temperature and polarization power spectra are consistent with the standard spatially-flat 6-parameter Lambda CDM cosmology with a power-law spectrum of adiabatic scalar perturbations (denoted "base Lambda CDM" in this paper). Apart from these tensions, the base ΛCDM cosmology provides an excellent description of the Planck CMB observations and many other astrophysical data sets. cosmological parameters; probe wmap observations; baryon acoustic-oscillations; microwave background anisotropies; redshift-space distortions; south-pole telescope; annihilating dark-matter; spt-sz survey; cmb spectral distortions; angular power spectrum; large-scale structure; 115 astronomy, space science; 114 physical sciences PDF.

If the true value of the cosmological curvature parameter is larger than 10 −3 we will be able to distinguish between these three models even now. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission Cosmological parameters. These data are consistent with the six-parameter inflationary LCDM cosmology.

Liddle (University of Edinburgh). 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. Planck 2015 results - VII. Note that in this abstract we quote 68% confidence limits on measured parameters and 95% upper limits on other parameters. Get help: See the main ReadMe file for program documentation and download. Finally, we briefly discuss updated results from the Planck 2015 data release as well as future prospects for CMB experiments. 1. Adding the BKP B-mode data to our analysis leads to a tighter constraint of r(0.002) < 0.09 and disfavours inflationary models with a V(phi) proportional to phi(2) potential. 24.1. 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. For a full description see the parameters paper. 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. Discussions and conclusions of the paper are provided in Sec. Astropart.Phys. This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) Combined with the Planck temperature and lensing data, these measurements give a reionization optical depth of tau = 0.066 +/- 0.016, corresponding to a reionization redshift of z(re) = 8.8(-1.4)(+1.7) These results are consistent with those from WMAP polarization measurements cleaned for dust emission using 353-GHz polarization maps from the High Frequency Instrument. (2016). We specifically compare sky maps, power spectra, and the inferred Λ cold dark matter (ΛCDM) cosmological parameters. We also constraints on annihilating dark matter and on possible deviations from the standard recombination history. Cosmological parameters | severely abridged - Subm.
