R. and others", title = "{Planck 2015 results. 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. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission This paper presents cosmological results based on full-mission Planck observations of temperature and polarization anisotropies of the cosmic microwave background (CMB) 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. The temperature and polarization power spectra are consistent with … However, as in the 2013 analysis, the amplitude of the fluctuation spectrum is found to be higher than inferred from some analyses of rich cluster counts and weak gravitational lensing. With four unified, simplified and workable assumptions, a number of useful cosmological formulae can be generated and the current Hubble parameter and current microwave back ground temperature can be fitted accurately. @article{Aghanim2020Planck2R, title={Planck 2018 results. With the proposed assumptions: 1) The intended purpose of ‘lambda’ term can be understood and in future it can be relinquished. Planck 2015 results: XIII. Note that in this abstract we quote 68% confidence limits on measured parameters and 95% upper limits on other parameters. (2016). 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. We present the first results of polarization measurements with the Low Frequency Instrument at large angular scales. We present results based on full-mission Planck observations of temperature and polarization anisotropies of the CMB. ISSN 0004-6361 When the additional informa- 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. Cosmological parameters: Author(s): Ade, P.A.R. The Planck results for base ΛCDM are in good agreement with baryon acoustic oscillation data and with the JLA sample of Type Ia supernovae. These data are consistent with the six-parameter inflationary LCDM cosmology. The main goal of the work is to constrain the free parameters of the model utilizing the latest observational data released by Planck-2015 [19, 25]. Adding a tensor component as a single-parameter extension to base ΛCDM we find an upper limit on the tensor-to-scalar ratio of r0.002< 0.11, consistent with the Planck 2013 results and consistent with the B-mode polarization constraints from a joint analysis of BICEP2, Keck Array, and Planck (BKP) data. The sum of neutrino masses is constrained to ∑ mν < 0.23 eV. 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. We find no evidence for any contribution from isocurvature perturbations or from cosmic defects. The spatial curvature of our Universe is found to be very close to zero, with | ΩK | < 0.005. Publication year: 2016: Source: Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. XIII. These results are consistent with those from WMAP polarization measurements cleaned for dust emission using 353-GHz polarization maps from the High Frequency Instrument. 1. Our results are in very good agreement with the 2013 analysis of the Planck nominal-mission temperature data, but with increased precision. The standard big bang nucleosynthesis predictions for the helium and deuterium abundances for the best-fit Planck base ΛCDM cosmology are in excellent agreement with observations.

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.

The spatial curvature of our Universe is found to be very close to zero, with | ΩK | < 0.005. Prediction of quantum perturbation is one of interesting features of inflationary scenario. The addition of Planck polarization data leads to strong constraints on deviations from a purely adiabatic spectrum of fluctuations. The sum of neutrino masses is constrained to â'mν < 0.23 eV.
