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.
Journal ArticleDOI

A Demonstration of Improved Constraints on Primordial Gravitational Waves with Delensing

P. A. R. Ade, +158 more
- 26 Jan 2021 - 
TL;DR: In this paper, the tensor-to-scalar ratio of the BICEP/Keck data set is reduced by cross-correlating against a lensing template.
Journal ArticleDOI

BICEP2 / Keck Array XI: Beam Characterization and Temperature-to-Polarization Leakage in the BK15 Dataset

Keck Array, +77 more
TL;DR: In this article, a cosmological constraint from observations with the BICEP2 and Keck Array experiments up to and including the 2015 observing season (BK15) was presented, resulting in the deepest CMB polarization maps to date and a statistical sensitivity to the tensor-to-scalar ratio of $\sigma(r) = 0.0027 \pm 0.020$.
Journal ArticleDOI

Microwave multiplexing on the Keck Array

A. Cukierman, +88 more
TL;DR: In this article, the authors describe an on-sky demonstration of a microwave-multiplexing readout system in one of the receivers of the Keck Array, a polarimetry experiment observing the cosmic microwave background at the South Pole.
