Planck 2013 results. XVI. Cosmological parameters
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +262 more
This paper presents the first cosmological results based on Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power spectra. We find that the Planck spectra at high multipoles (ℓ ≳ 40) are extremely well described by the standard spatially-flat six-parameter ΛCDM cosmology with a power-law spectrum of a…
Planck 2013 results. XXII. Constraints on inflation
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +241 more
We analyse the implications of the Planck data for cosmic inflation. The Planck nominal mission temperature anisotropy measurements, combined with the WMAP large-angle polarization, constrain the scalar spectral index to be ns = 0.9603 ± 0.0073, ruling out exact scale invariance at over 5σ.Planck establishes an upper bound on the tensor…
Planck 2013 results. I. Overview of products and scientific results
Böhringer, H.; Kneissl, R.; Dahle, H. +398 more
The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre sky continuously since 12 August 2009. In March 2013, ESA and the Planck Collaboration released the initial cosmology products based on the first 15.5 mo…
Planck 2013 results. XXIV. Constraints on primordial non-Gaussianity
Miville-Deschênes, M. -A.; Bernard, J. -P.; Planck Collaboration +237 more
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 primordial local, equilateral, and orthogonal bispectrum amplitudes, quoting as our…
Planck 2013 results. XI. All-sky model of thermal dust emission
Miville-Deschênes, M. -A.; Boulanger, F.; Abergel, A. +244 more
This paper presents an all-sky model of dust emission from the Planck 353, 545, and 857 GHz, and IRAS 100 µm data. Using a modified blackbody fit to the data we present all-sky maps of the dust optical depth, temperature, and spectral index over the 353-3000 GHz range. This model is a good representation of the IRAS and Planck data at 5' bet…
Planck 2013 results. XX. Cosmology from Sunyaev-Zeldovich cluster counts
Böhringer, H.; Kneissl, R.; Dahle, H. +252 more
We present constraints on cosmological parameters using number counts as a function of redshift for a sub-sample of 189 galaxy clusters from the Planck SZ (PSZ) catalogue. The PSZ is selected through the signature of the Sunyaev-Zeldovich (SZ) effect, and the sub-sample used here has a signal-to-noise threshold of seven, with each object confirmed…
Planck 2013 results. XV. CMB power spectra and likelihood
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +259 more
This paper presents the Planck 2013 likelihood, a complete statistical description of the two-point correlation function of the CMB temperature fluctuations that accounts for all known relevant uncertainties, both instrumental and astrophysical in nature. We use this likelihood to derive our best estimate of the CMB angular power spectrum from Pla…
Planck 2013 results. XXIII. Isotropy and statistics of the CMB
Kim, J.; Miville-Deschênes, M. -A.; Bernard, J. -P. +252 more
The two fundamental assumptions of the standard cosmological model - that the initial fluctuations are statistically isotropic and Gaussian - are rigorously tested using maps of the cosmic microwave background (CMB) anisotropy from the Planck satellite. The detailed results are based on studies of four independent estimates of the CMB that are com…
Planck 2013 results. XXIX. The Planck catalogue of Sunyaev-Zeldovich sources
Böhringer, H.; Kneissl, R.; Dahle, H. +273 more
We describe the all-sky Planck catalogue of clusters and cluster candidates derived from Sunyaev-Zeldovich (SZ) effect detections using the first 15.5 months of Planck satellite observations. The catalogue contains 1227 entries, making it over six times the size of the Planck Early SZ (ESZ) sample and the largest SZ-selected catalogue to date. It …
Planck 2013 results. XVII. Gravitational lensing by large-scale structure
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +238 more
On the arcminute angular scales probed by Planck, the cosmic microwave background (CMB) anisotropies are gently perturbed by gravitational lensing. Here we present a detailed study of this effect, detecting lensing independently in the 100, 143, and 217 GHz frequency bands with an overall significance of greater than 25σ. We use thetemperature-gra…
