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. We also constraints on annihilating dark matter and on possible deviations from the standard recombination history. Combined with the Planck temperature and lensing data, these measurements give a reionization optical depth of τ = 0.066 ± 0.016, corresponding to a reionization redshift of z_re=8.8+1.7-1.4. These data are consistent with the six-parameter inflationary LCDM cosmology. In this model Planck data determine the cosmological parameters to high precision. The Planck results for base ΛCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. Astronomy and Astrophysics, 594 (A13). Cosmological Parameter Estimation We calculate the constraints on di erent cosmological parameters using WMAP-9, Planck and BICEP 2 likelihood.

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. Neutrinos. These data are consistent with the six-parameter inflationary LCDM cosmology. Add your e-mail address to receive free newsletters from SCIRP. Updated November 2015, by O.

The Planck mission has had two cosmological data releases so far, in 2013 and in 2015. 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. The Planck results for base Lambda CDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. Residual dipoles are 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]. 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. The standard big bang nucleosynthesis predictions for the helium and deuterium abundances for the best-fit Planck base Lambda CDM cosmology are in excellent agreement with observations. 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. Our books collection spans in multiple locations, allowing you to get the most less latency time to download any of our books like this one. 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). Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. 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 Omega(m) = 0.308 +/- 0.012, and a tilted scalar spectral index with ns = 0.968 +/- 0.006, consistent with the 2013 analysis. 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. In general, the Planck mission’s complete results confirm the canonical cosmological model, known as Lambda Cold Dark Matter, or ΛCDM. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission By A Lewis, D Munshi and et al.

XIII. 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. The spatial curvature of our Universe is found to be very close to zero, with vertical bar Omega(K)vertical bar < 0.005. The Planck spectra at high multipoles are extremely well described by the standard spatially-flat six-parameter LCDM cosmology. et al. Adding a tensor component as a single-parameter extension to base Lambda CDM we find an upper limit on the tensor-to-scalar ratio of r(0.002) < 0.11, consistent with the Planck 2013 results and consistent with the B-mode polarization constraints from a joint analysis of BICEP2, Keck Array, and Planck (BKP) data. In a universe with zero curvature, the local geometry is flat. XIII. The addition of Planck polarization data leads to strong constraints on deviations from a purely adiabatic spectrum of fluctuations. Abstract.
