1 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. XIII. The sum of neutrino masses is constrained to â'mν < 0.23 eV. We also constraints on annihilating dark matter and on possible deviations from the standard recombination history. Adding a tensor component as a single-parameter extension to base ΛCDM we find an upper limit on the tensor-to-scalar ratio of r0.002< 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.

(2016). Note that in this abstract we quote 68% confidence limits on measured parameters and 95% upper limits on other parameters. These data are consistent with the six-parameter inflationary LCDM cosmology. 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. XIII. The spatial curvature of our Universe is found to be very close to zero, with | ΩK | < 0.005. Planck 2015 Results: Cosmological Parameter Tables January 19, 2015 Abstract These tables summarize the results of Planck 2015 parameter estimation exploration results. Received 2014 September 26; accepted 2015 January 14; published 2015 February 24 ABSTRACT We examine the consistency of the 9yr WMAP data and the first-release Planck data. 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.

Note that in this abstract we quote 68% confidence limits on measured parameters and 95% upper limits on other parameters.

R., Aghanim, N., Arnaud, M., Ashdown, M., Aumont, J., et al. In general, the Planck mission’s complete results confirm the canonical cosmological model, known as Lambda Cold Dark Matter, or ΛCDM. We present the first results of polarization measurements with the Low Frequency Instrument at large angular scales. Title: Planck 2015 results. 1. Cosmological parameters | severely abridged - Subm. The Planck results for base ΛCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. 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. Cited 3469 times in Scopus. The temperature and polarization power spectra are consistent with the standard spatially-flat 6-parameter ΛCDM cosmology with a power-law spectrum of adiabatic scalar perturbations (denoted "base ΛCDM" in this paper). This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. 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 main goal of the work is to constrain the free parameters of the model utilizing the latest observational data released by Planck-2015 [19, 25]. 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. (2016) Planck 2015 results. This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) 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. Cosmological parameters. 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 temperature data, but with increased precision. On this page you can find a list of Planck publications, ordered as follows. Planck was a space observatory operated by the European Space Agency (ESA) from 2009 to 2013, which mapped the anisotropies of the cosmic microwave background (CMB) at microwave and infra-red frequencies, with high sensitivity and small angular resolution.The mission substantially improved upon observations made by the NASA Wilkinson Microwave Anisotropy Probe (WMAP). Cosmological parameters. By A Lewis, D Munshi and et al. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. We specifically compare sky maps, power spectra, and the inferred Λ cold dark matter (ΛCDM) cosmological parameters. For example, Larson et al. 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 find no evidence for any contribution from isocurvature perturbations or from cosmic defects. Adding the BKP B-mode data to our analysis leads to a tighter constraint of r0.002 < 0.09 and disfavours inflationarymodels with a V(φ) ∝ φ2 potential.

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. 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. Planck 2015 results: XIII. The WMAP and Planck 2015 TT spectra now appear to be in agreement over their common multipole range (Figure 46 of Planck Collaboration XI 2015). 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 addition of Planck polarization data leads to strong constraints on deviations from a purely adiabatic spectrum of fluctuations. Prediction of quantum perturbation is one of interesting features of inflationary scenario. 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 \hbox{$z-{\rm re}=8.8{+1.7}-{-1.4}$}.
