1. between the cosmological parameters inferred. © 2016 ESO. 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. The Planck results for base ΛCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. Cosmological parameters: Author(s): Ade, P.A.R. We present the first results of polarization measurements with the Low Frequency Instrument at large angular scales. Received 6 February 2015 / Accepted 4 June 2016 ABSTRACT This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. @article{Aghanim2020Planck2R, title={Planck 2018 results. The addition of Planck polarization data leads to strong constraints on deviations from a purely adiabatic spectrum of fluctuations. 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. 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. XIII. Compared to the 2015 results, improved measurements of large-scale polarization allow the reionization optical depth to be measured with … The Planck Collaboration. Planck 2015 results. We present results based on full-mission Planck observations of temperature and polarization anisotropies of the CMB. XIII. Let us know how this access is important for you. 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. We also constraints on annihilating dark matter and on possible deviations from the standard recombination history. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. 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 . Liddle (University of Edinburgh). The Planck 2015 cosmological parameters using both temperature and polarization data are in very good agreement with those from the 2013 release, but with significantly improved precision. With the proposed assumptions: 1) The intended purpose of ‘lambda’ term can be understood and in future it can be relinquished. In neither case do we find no evidence for new physics. VI. The sum of neutrino masses is constrained to â'mν < 0.23 eV. XIII. For example, Larson et al. 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. 594, article id A13 Article in journal (Refereed) Published Abstract [en] This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation.

Astronomy and Astrophysics, 594 (A13). 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. 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.

This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information from the temperature and polarization maps and the lensing reconstruction. 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 +/- 0.006. This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) radiation. 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). Planck 2015 results. 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).
