BICEP / Keck XIII: Improved Constraints on Primordial Gravitational Waves using Planck, WMAP, and BICEP/Keck Observations through the 2018 Observing Season
Keck Collaboration, P. A. R. Ade, Z. Ahmed +89
We 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. We add additi…
Observing low elevation sky and the CMB Cold Spot with BICEP3 at the South Pole
J. Kang, P. A. R. Ade, Z. Ahmed +84
BICEP3 is a 520 mm aperture on-axis refracting telescope at the South Pole, which observes the polarization of the cosmic microwave background (CMB) at 95 GHz to search for the B-m…
A Demonstration of Improved Constraints on Primordial Gravitational Waves with Delensing
BICEP/Keck, SPTpol Collaborations, : +139
We present a constraint on the tensor-to-scalar ratio, , derived from measurements of cosmic microwave background (CMB) polarization -modes with "delensing," whereby the unce…
Optical characterization of the Keck Array and BICEP3 CMB Polarimeters from 2016 to 2019
Keck Collaboration, T. St Germaine, P. A. R. Ade +71
The BICEP/Keck experiment (BK) is a series of small-aperture refracting telescopes observing degree-scale Cosmic Microwave Background (CMB) polarization from the South Pole in sear…
Microwave multiplexing on the Keck Array
Ari Cukierman, Zeeshan Ahmed, Shawn Henderson +82
We 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 ba…
BICEP2 / Keck Array XI: Beam Characterization and Temperature-to-Polarization Leakage in the BK15 Dataset
Keck Array, BICEP2 Collaborations, : +76
Precision measurements of cosmic microwave background (CMB) polarization require extreme control of instrumental systematics. In a companion paper we have presented cosmological co…
