The Planck 95% CL upper limit on the tensor-to-scalar ratio, r0.002 < 0.10, is further tightened by combining with the BICEP2/Keck Array BK15 data to obtain r0.002 < 0.056. Planck 2018 results.

Planck 2018 results. 1 Introduction Four decades after the introduction of the inflation model, it can now be considered as one of the cornerstones of modern cosmology [1–9]. 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. Astronomy & Astrophysics manuscript no. The properties of matter under such extreme conditions are poorly understood and inaccessible to terrestrial laboratories. Planck power spectra plus lensing set constraints on the amplitude of compensated cold dark matter-baryon isocurvature perturbations that are consistent with current complementary measurements. The constraints on αEM tighten slightly due to improved Planck 2018 polarization data but otherwise remain similar to previous CMB analysis. Planck 2018 results. – Planck and BK14 data set tight constraints on α attractors (Kallosh et al. Reference cases for CMB + BAO and CMB + BAO + R19 are included. Isotropy and statistics Planck 2018 results. 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. We present cosmological parameter results from the final full-mission Planck measurements of the cosmic microwave background (CMB) anisotropies, combining information f 39 2.2 Calculations of N e including the neutrinos oscillation e ects [2], ˆ = ˆ =ˆ 0 , which gives the well-known value N Planck 2018 results. 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 perform several comparative analyses using the latest cosmological recombination calculations to further understand the various effects. We find no evidence for a scale dependence of ns, either as a running or as a running of the running.

Isotropy and Statistics of the CMB” by the Planck Collaboration is published in Astronomy & Astrophysics. – Planck 2018 data strongly disfavour the hybrid model driven by logarithmic quantum corrections in spontaneously broken supersymmetric (SUSY) theories (Dvali et al.

CMB power spectra and likelihoods; Characterization of the in-flight properties of the Planck telescope; Characterization of the in-flight properties of the Planck … Planck; Collaboration • Y. Akrami (Leiden U. and ; Inst. We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. We present updated constraints on the variation of the fine structure constant, αEM, and effective electron rest mass, me, during the cosmological recombination era. VI. arXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website. • Planck 2018 results. Planck has substantially tightened the constraints on slow-roll inflationary models, ruling out hybrid models with ns > 1 and power-law inflation (PCI13). 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. arXiv is committed to these values and only works with partners that adhere to them. temperature (Aylor et al. The Universe is found to be consistent with spatial flatness with a precision of 0.4% at 95% CL by combining Planck with a compilation of baryon acoustic oscillation data. Dietrich et al. “Planck 2018 results. We present new constraints on extended cosmological scenarios using the recent data from the Planck 2018 Legacy release. 50 pages. Combined with baryon density and other weak priors, the lensing analysis alone constrains σ8Ωm0.25 = 0.589 ± 0.020 (1σ errors).

I Can write the potential in … 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. The results are fully consistent with those reported using the data from the two previous Planck cosmological releases, but have smaller uncertainties thanks to improvements in the characterization of polarization at low and high multipoles. We also give a comprehensive summary of the major changes introduced in this 2018 release.
