Planck 2015 results. XIII. Cosmological parameters
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +259 more
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. The temperature and polarizat…
Planck 2015 results. XX. Constraints on inflation
Kneissl, R.; Kim, J.; Miville-Deschênes, M. -A. +244 more
We present the implications for cosmic inflation of the Planck measurements of the cosmic microwave background (CMB) anisotropies in both temperature and polarization based on the full Planck survey, which includes more than twice the integration time of the nominal survey used for the 2013 release papers. The Planck full mission temperature data …
Planck 2015 results. I. Overview of products and scientific results
Böhringer, H.; Kneissl, R.; Kim, J. +367 more
The European Space Agency's Planck satellite, which is dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between 12 August 2009 and 23 October 2013. In February 2015, ESA and the Planck Collaboration released the second set of cosmology pr…
Planck 2015 results. XI. CMB power spectra, likelihoods, and robustness of parameters
Miville-Deschênes, M. -A.; Boulanger, F.; Bernard, J. -P. +221 more
This paper presents the Planck 2015 likelihoods, statistical descriptions of the 2-point correlationfunctions of the cosmic microwave background (CMB) temperature and polarization fluctuations that account for relevant uncertainties, both instrumental and astrophysical in nature. They are based on the same hybrid approach used for the previous rel…
Planck 2015 results. XIV. Dark energy and modified gravity
Miville-Deschênes, M. -A.; Bernard, J. -P.; Planck Collaboration +234 more
We study the implications of Planck data for models of dark energy (DE) and modified gravity (MG) beyond the standard cosmological constant scenario. We start with cases where the DE only directly affects the background evolution, considering Taylor expansions of the equation of state w(a), as well as principal component analysis and parameterizat…
Big bang nucleosynthesis: Present status
Fields, Brian D.; Cyburt, Richard H.; Olive, Keith A. +1 more
Big bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a dynamic interplay among the four fundamental forces during the first seconds of cosmic time. A brief overview of the essentials of this physics is given, and new calculations presented of light-element abundances through 6Li and 7Li, with u…
Planck 2015 results. XXIV. Cosmology from Sunyaev-Zeldovich cluster counts
Kneissl, R.; Miville-Deschênes, M. -A.; Bernard, J. -P. +233 more
We present cluster counts and corresponding cosmological constraints from the Planck full mission data set. Our catalogue consists of 439 clusters detected via their Sunyaev-Zeldovich (SZ) signal down to a signal-to-noise ratio of 6, and is more than a factor of 2 larger than the 2013 Planck cluster cosmology sample. The counts are consistent with…
Planck 2015 results. XVII. Constraints on primordial non-Gaussianity
Kim, J.; Miville-Deschênes, M. -A.; Boulanger, F. +239 more
The Planck full mission cosmic microwave background (CMB) temperature and E-mode polarization maps are analysed to obtain constraints on primordial non-Gaussianity (NG). Using three classes of optimal bispectrum estimators - separable template-fitting (KSW), binned, and modal - we obtain consistent values for the primordial local, equilateral, and…
Planck 2015 results. XXVII. The second Planck catalogue of Sunyaev-Zeldovich sources
Böhringer, H.; Kneissl, R.; Dahle, H. +257 more
We present the all-sky Planck catalogue of Sunyaev-Zeldovich (SZ) sources detected from the 29 month full-mission data. The catalogue (PSZ2) is the largest SZ-selected sample of galaxy clusters yet produced and the deepest systematic all-sky surveyof galaxy clusters. It contains 1653 detections, of which 1203 are confirmed clusters with identified…
Improved Constraints on Cosmology and Foregrounds from BICEP2 and Keck Array Cosmic Microwave Background Data with Inclusion of 95 GHz Band
Ade, P. A. R.; Bock, J. J.; Crill, B. P. +59 more
We present results from an analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season. This includes the first Keck Array observations at 95 GHz. The maps reach a depth of 50 nK deg in Stokes Q and U in the 150 GHz band and 127 nK deg in the 95 GH…
