IV. 966 and tensor–scalar ratio, R < 0. VIII. X. We report on the implications for cosmic inflation of the 2018 release of the Planck cosmic microwave background (CMB) anisotropy measurements. CMB and foreground extraction • Planck 2018 results. • Planck 2018 results. XI. III. Abstract. The results are fully consistent with the two previous Planck cosmological releases, but have smaller uncertainties thanks to improvements in the … What have the Planck data taught us about inflation? The dark (light) blue area is the Planck 2018 1σ (2σ) region, with an account taken of TT, TE, EE + lowE + lensing + BK14+BAO [1]. 16. We show that a combination of the simplest α attractors and KKLT inflation models related to Dp-brane inflation covers most of the area in the (n s, r) space favored by Planck 2018. High Frequency Instrument data processing • Planck 2018 results. This content was downloaded from IP address 157.55.39.170 on 11/06/2018 at 23:25. We revisit phenomenological as well as string-theoretical aspects of D-brane inflation cosmological models. We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. Both individuals and organizations that work with arXivLabs have embraced and accepted our values of openness, community, excellence, and user data privacy. This highlights of Planck 2018 results.X. The Planck consortium publishes the full and final version of these data and associated articles on the ESA website on 17 July 2018. Constraints on inflation, arXiv:1807.06211, L10 of this release will be covered as a list of key questions relevant for inflation: The recent Planck 2018 data sets bounds for scalar power spectrum, scalar spectral index, n s = 0. We report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements. VI. Gravitational lensing • Planck 2018 results. 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 have plotted graphical trajectories of R − n s by constraining the model parameters, which show that Planck bounds are fully satisfied by Rastall theory of gravity. Cosmological parameters • Planck 2018 results. arXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website. arXiv is committed to these values and only works with partners that adhere to them.
