# planck 2018 constraints

The Planck data, alone and in combination with other probes, provide stringent constraints on our models of the early Universe and the large-scale structure within which all astrophysical objects form and evolve. The results are based on the Planck legacy data release, which was made public on 17 July 2018. Does ns depend on the wavelength? On this page you can find a list of Planck publications, ordered as follows. Further adding supernova data yields |$m_{\rm e}=(1.0190\pm 0.0055)\, m_{\rm e,0}$| with H0 = 71.24 ± 0.96.

If you originally registered with a username please use that to sign in. Constraints on primordial non-gaussianity. We also give a comprehensive summary of the major changes introduced in this 2018 release. Is the Universe spatially flat? VII. Also combining with baryon acoustic oscillation data, we find tight individual parameter constraints, σ8 = 0.811 ± 0.019, H0 = 67.9−1.3+1.2 km s−1 Mpc−1, and Ωm = 0.303−0.018+0.016. Planck temperature, polarization, and lensing data determine the spectral index of scalar perturbations to be ns = 0.9649 ± 0.0042 at 68% CL. Constraints on inflation - INSPIRE. However, a comparison with the 2015 constraints reveals a mildly discordant behaviour for me, which from CMB data alone is found below its local value. I Idea is that in ation takes place near a maximum of potential. We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. A&A, Forthcoming article. We combine the Planck CMB anisotropy data in temperature with the low-multipole polarization data to fit ΛCDM models with various parameterizations of the reionization history. I.

They are based on Planck HFI data and Planck lensing, as well as additional non-CMB data as detailed in the main parameter papers. The results are fully consistent with the two previous Planck cosmological releases, but have smaller uncertainties thanks to improvements in the characterization of polarization at low and high multipoles. A complementary analysis also finds no evidence for theoretically motivated parameterized features in the Planck power spectra. with Planck <≈0.01% For comparison: – Flatness in second place with now ~0.1% – Isocurvature constraints ~1% (hence tight constraints on topological defects, such as cosmic strings) Ben Wandelt, COSPAR 2018, July 2018 Polarized dust foregrounds Planck Collaboration, et.al., astro-ph.

Lett. Banday, R.B. 2017) and SPTpol polarization (JWH, et al. The polarization data also provide improved constraints on inflationary models that predict a small statistically anisotropic quadrupolar modulation of the primordial fluctuations. Planck 2018 results. The results are fully consistent with the two previous Planck cosmological releases, but have smaller uncertainties thanks to improvements in the characterization of polarization at low and high multipoles. We compare estimates obtained from separable template-fitting, binned, and optimal modal bispectrum estimators, finding consistent values for the local, equilateral, and orthogonal bispectrum amplitudes. e-Print: 1905.05697 [astro-ph.CO] Accelerator experiments: PLANCK; View in: HAL Archives Ouvertes, ADS Abstract Service; pdf cite. All these findings support the key predictions of the standard single-field inflationary models, which will be further tested by future cosmological observations. We present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the Cosmic Microwave Background anisotropies provided by the Planck satellite.

Combined with baryon density and other weak priors, the lensing analysis alone constrains σ8Ωm0.25 = 0.589 ± 0.020 (1σ errors). We find no evidence for a scale dependence of ns, either as a running or as a running of the running. We perform several comparative analyses using the latest cosmological recombination calculations to further understand the various effects. Planck 2018 results. Why primordial non-Gaussianity? IX.

We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We use data from Supernovae (SNIa) Scolnic sample, from Baryonic Acoustic Oscillations (BAO), and from cosmic chronometers measurements of the Hubble parameter (CC), alongside arguments from Big Bang Nucleosynthesis (BBN), in order to extract constraints on Myrzakulov F(R,T ) gravity.

However, the polarization data do not confirm physical models for a scale-dependent dipolar modulation. XI. The new Planck polarization data provide a stringent test of the adiabaticity of the initial conditions for the cosmological fluctuations. Adding baryon acoustic oscillation data brings me back to the fiducial value, |$m_{\rm e}=(1.0078\pm 0.0067)\, m_{\rm e,0}$|⁠, and also drives the Hubble parameter to H0 = 69.1 ± 1.2(in units of |${\rm km \, s^{-1} \, Mpc^{-1} }$|⁠). – Planck 2018 data strongly disfavour the hybrid model driven by logarithmic quantum corrections in spontaneously broken supersymmetric (SUSY) theories (Dvali et al. Our results indicate that a single-parameter extension allowing a slightly increased value of me (≃3.5σ above me, 0) could play a role in the Hubble tension. V.

VII. … 50 pages. For the case of oscillatory features that are logarithmic or linear in k, this result is further strengthened by a new combined analysis including the Planck bispectrum data. These two fundamental constants directly affect the ionization history at redshift z ≃ 1100 and, thus, modify the temperature and polarization anisotropies of the cosmic microwave background (CMB) measured precisely with Planck . With 18 peaks in the temperature and polarization angular power spectra constrained well, Planck measures five of the six parameters to better than 1 % (simultaneously), with the best-determined parameter (θ ∗) now known to 0.03 %.
