Journal ArticleDOI

Planck 2015 results. XX. Constraints on inflation

TL;DR: In this article, the authors report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements, which 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.

Planck 2015 results: XIV. Dark energy and modified gravity

Peter A. R. Ade, +304 more
TL;DR: In this paper, the implications of Planck data for models of dark energy (DE) and modified gravity (MG) beyond the standard cosmological constant scenario were studied, and it was shown that the density of DE at early times has to be below 2% of the critical density, even when forced to play a role for z < 50.

Planck 2015 results. XIV. Dark energy and modified gravity

Peter A. R. Ade, +233 more
TL;DR: In this paper, the implications of Planck data for models of dark energy (DE) and modified gravity (MG), beyond the cosmological constant scenario, were studied, and a range of specific models, such as k-essence, f(R) theories and coupled DE scalar field were tested.
Journal ArticleDOI

Planck 2013 results - XXIII. Isotropy and statistics of the CMB

Peter A. R. Ade, +313 more
TL;DR: In this article, the statistical isotropy and Gaussianity of the cosmic microwave background (CMB) anisotropies using observations made by the Planck satellite were investigated.
