Detection of $B$-Mode Polarization at Degree Angular Scales by BICEP2

TL;DR: An excess of B-mode power over the base lensed-ΛCDM expectation is found in the range 30 < ℓ < 150, inconsistent with the null hypothesis at a significance of >5σ, and it is shown that systematic contamination is much smaller than the observed excess.
Journal ArticleDOI

Joint Analysis of BICEP2/Keck Array and Planck Data

Peter A. R. Ade, +357 more
TL;DR: Strong evidence for dust and no statistically significant evidence for tensor modes is found and various model variations and extensions are probe, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint.
Journal ArticleDOI

Improved Constraints on Cosmology and Foregrounds from BICEP2 and Keck Array Cosmic Microwave Background Data with Inclusion of 95 GHz Band

TL;DR: An analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season yields an upper limit r_{0.05}<0.09 at 95% confidence, which is robust to variations explored in analysis and priors.
Journal ArticleDOI

Constraints on Primordial Gravitational Waves Using Planck, WMAP, and New BICEP2/Keck Observations through the 2015 Season.

Peter A. R. Ade, +84 more
TL;DR: Results from an analysis of all data taken by the bicep2/Keck CMB polarization experiments up to and including the 2015 observing season are presented, showing the strongest constraints to date on primordial gravitational waves.
Journal ArticleDOI

Improved Constraints on Primordial Gravitational Waves using Planck, WMAP, and BICEP/Keck Observations through the 2018 Observing Season.

P. A. R. Ade, +91 more
TL;DR: In this paper, the authors present results from an analysis of all data taken by the BICEP2, Keck Array, and BiceP3 CMB polarization experiments up to and including the 2018 observing season.
