Request PDF | Planck 2015 results. 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). On this page you can find a list of Planck publications, ordered as follows. By A Lewis, D Munshi and et al. 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 adiabatic scalar perturbations.

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). The Planck 2015 cosmogical results are discussed with an emphasis on the improvements compared to the last data release, and on the methodology used to extract the parameters, both for the likelihood building and for the statistical method.

Publication year: 2016: Source: This paper presents the first cosmological results based on Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power spectra. The Planck base-ΛCDM results are in good agreement with BAO, SNe, and some galaxy lensing observations, but in slight tension with the Dark Energy Survey’s combined-probe results including galaxy clustering (which prefers lower fluctuation amplitudes or matter density parameters), and in significant, 3.6σ, tension with local measurements of the Hubble constant (which prefer a higher value). Cosmological parameters . CMB power spectra, likelihoods, and robustness of parameters. 1. The cosmological parameters are set to Ω m = 0.301, Ω b = 0.0457, = 0.961, 0 = 70.2 km s −1 Mpc −1 and 8 = 0.829 (Ade et al. From the Planck temperature and lensing data, for this cosmology we find a Hubble constant, H0= (67.8 +/- 0.9) km/s/Mpc, a matter density parameter Omega_m = 0.308 +/- 0.012 and a scalar spectral index with n_s = 0.968 +/- … Compared to the 2015 results, Papers by the Planck Collaboration, categorized into groups: Planck 2018 results /Planck 2015 results /Joint BICEP2 Keck Planck 2015 results /Planck 2013 results / Planck intermediate results (2012 -...) / Planck early results (2011) / Pre-launch results (2010) / Technical results (2003 - ...) / The Scientific Programme of Planck(2005) 2.

These data are consistent with the six-parameter inflationary LCDM cosmology. XIII. Results of the Planck mission released in 2015 show the cosmological curvature parameter, Ω K, to be 0.000±0.005, consistent with a flat universe. 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. XVI. Cosmological parameters.

Much more precise spacecraft measurements of the microwave background from WMAP in 2003–2010 and Planck in 2013–2015 have continued to support the model and pin down the parameter values, most of which are now constrained below 1 percent uncertainty. Abstract. This leaves seven parameters, which is the smallest set that can usefully be compared to the present cosmological data set. Planck Collaboration, P. A. R. Ade, N. Aghanim, M. Arnaud, M.

The Planck results for base LambdaCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. 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. This model is referred to by various names, including ΛCDM, the concordance cosmology, and the standard cosmological model. The European Space Agency's Planck satellite, which was dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision.
