Use, Smithsonian Request PDF | Planck 2015 results. 1 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. 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. (2016) Planck 2015 results. 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. 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. Planck 2015 results : XIII. Abstract. 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 Planck results for base ΛCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative 2. The sum of neutrino masses is constrained to Sigma m(v) < 0.23 eV. Open Access LMU is powered by EPrints 3, which is developed by the School of Electronics and Computer Science at the University of Southampton. XIII. This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. Cosmology. Discussions and conclusions of the paper are provided in Sec. Planck 2015 results - XVI. Abstract. These results are consistent with those from WMAP polarization measurements cleaned for dust emission using 353-GHz polarization maps from the High Frequency Instrument. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission We present the first results of polarization measurements with the Low Frequency Instrument at large angular scales. Residual dipoles are The predicted tSZ power spectrum agrees with that of the Planck data at all multipoles up to l ≈ 1000, once the calculations are scaled to the Planck 2015 cosmological parameters with Ω m = 0.308 and σ8 = 0.8149.

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. In general, the Planck mission’s complete results confirm the canonical cosmological model, known as Lambda Cold Dark Matter, or ΛCDM. 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. We specifically compare sky maps, power spectra, and the inferred Λ cold dark matter (ΛCDM) cosmological parameters.

These data are consistent with the six-parameter inflationary LCDM cosmology. 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. (2016). 44).
