We present results based on full-mission Planck observations of temperature and polarization anisotropies the CMB. These data are consistent with six-parameter inflationary LCDM cosmology. From lensing data, for this cosmology we find a Hubble constant, H0= (67.8 +/- 0.9) km/s/Mpc, matter density parameter Omega_m = 0.308 0.012 scalar spectral index n_s 0.968 0.006. (We quote 68% errors measured parameters 95% limits other parameters.) Combined LFI measurements lead to reionization optical...

We present the first results based on Planck measurements of CMB temperature and lensing-potential power spectra. The spectra at high multipoles are extremely well described by standard spatially-flat six-parameter LCDM cosmology. In this model data determine cosmological parameters to precision. find a low value Hubble constant, H0=67.3+/-1.2 km/s/Mpc matter density parameter, Omega_m=0.315+/-0.017 (+/-1 sigma errors) in excellent agreement with constraints from baryon acoustic oscillation...

We analyse the implications of Planck data for cosmic inflation. The nominal mission temperature anisotropy measurements, combined with WMAP large-angle polarization, constrain scalar spectral index to $n_s = 0.9603 \pm 0.0073$, ruling out exact scale invariance at over 5 $\sigma$. establishes an upper bound on tensor-to-scalar ratio r < 0.11 (95% CL). thus shrink space allowed standard inflationary models, preferring potentials V" 0.

We report the results of a joint analysis data from BICEP2/Keck Array and Planck. BICEP2 Keck have observed same approximately 400 deg$^2$ patch sky centered on RA 0h, Dec. $-57.5\deg$. The combined maps reach depth 57 nK deg in Stokes $Q$ $U$ band at 150 GHz.

This paper presents the Planck 2015 likelihoods, statistical descriptions of 2-point correlations CMB data, using hybrid approach employed previously: pixel-based at $\ell<30$ and a Gaussian approximation to distribution spectra higher $\ell$. The main improvements are use more better processed data polarization detailed foreground instrumental models, allowing further checks enhanced immunity systematics. Progress in modelling enables larger sky fraction. Improvements processing models...

The Planck nominal mission cosmic microwave background (CMB) maps yield unprecedented constraints on primordial non-Gaussianity (NG). Using three optimal bispectrum estimators, separable template-fitting (KSW), binned, and modal, we obtain consistent values for the local, equilateral, orthogonal amplitudes, quoting as our final result fNL^local= 2.7+/-5.8, fNL^equil= -42+/-75, fNL^ortho= -25+\-39 (68% CL statistical). NG is detected in data; using skew-C_l statistics find a nonzero from...
