BICEP2 / Keck Array x: Constraints on Primordial Gravitational Waves using Planck, WMAP, and New BICEP2/Keck Observations through the 2015 Season
Keck Array, BICEP2 Collaborations, : +78
We present results from an analysis of all data taken by the BICEP2/Keck CMB polarization experiments up to and including the 2015 observing season. This includes the first Keck Ar…
Measurements of Degree-Scale B-mode Polarization with the BICEP/Keck Experiments at South Pole
Keck Collaboration, P. A. R. Ade, Z. Ahmed +76
The BICEP and Keck Array experiments are a suite of small-aperture refracting telescopes observing the microwave sky from the South Pole. They target the degree-scale B-mode polari…
BICEP2 / Keck Array IX: New Bounds on Anisotropies of CMB Polarization Rotation and Implications for Axion-Like Particles and Primordial Magnetic Fields
Keck Array, BICEP2 Collaborations, : +65
We present the strongest constraints to date on anisotropies of cosmic microwave background (CMB) polarization rotation derived from 150 GHz data taken by the BICEP2/Keck Array CMB…
The Cosmic Microwave Background And Pseudo-Nambu-Goldstone Bosons: Searching For Lorentz Violations In The Cosmos
David Leon, Jonathan Kaufman, Brian Keating +1
One of the most powerful probes of new physics is the polarized Cosmic Microwave Background (CMB). The detection of a nonzero polarization angle rotation between the CMB surface of…
BICEP2 / Keck Array VIII: Measurement of gravitational lensing from large-scale B-mode polarization
The Keck Array, BICEP2 Collaborations, : +63
We present measurements of polarization lensing using the 150 GHz maps which include all data taken by the BICEP2 & Keck Array CMB polarization experiments up to and including the…
Using the Crab Nebula as a high precision calibrator for Cosmic Microwave Background polarimeters
Jonathan Kaufman, Brian Keating, David Leon
The polarization of the Cosmic Microwave Background (CMB) provides a plethora of information about the early universe. Most notably, gravitational waves from the Inflationary epoch…
