BICEP/Keck XXI: Constraints on Early-Universe Parity Violation from Multipole-Dependent Birefringence
Keck Collaboration, P. A. R. Ade, Zeeshan Ahmed +94
We present the first constraints on multipole-dependent cosmic birefringence using CMB polarization data from the BK18 dataset, which combines observations from BICEP2, Keck Array,…
Calibration Measurements of the BICEP3 and BICEP Array CMB Polarimeters from 2017 to 2024
Christos Giannakopoulos, Clara Vergès, P. A. R. Ade +83
The BICEP3 and BICEP Array polarimeters are small-aperture refracting telescopes located at the South Pole designed to measure primordial gravitational wave signatures in the Cosmi…
Design and Performance of 30/40 GHz Diplexed Focal Plane for BICEP Array
Corwin Shiu, Ahmed Soliman, Roger O'Brient +11
We demonstrate a wide-band diplexed focal plane suitable for observing low-frequency foregrounds that are important for cosmic microwave background polarimetry. The antenna element…
Improved Polarization Calibration of the BICEP3 CMB Polarimeter at the South Pole
J. Cornelison, C. Vergès, P. A. R. Ade +83
The BICEP3 Polarimeter is a small aperture, refracting telescope, dedicated to the observation of the Cosmic Microwave Background (CMB) at 95GHz. It is designed to target degree an…
Thermal Testing for Cryogenic CMB Instrument Optical Design
D. C. Goldfinger, P. A. R. Ade, Z. Ahmed +83
Observations of the Cosmic Microwave Background rely on cryogenic instrumentation with cold detectors, readout, and optics providing the low noise performance and instrumental stab…
Snowmass2021 Cosmic Frontier: Cosmic Microwave Background Measurements White Paper
Clarence L. Chang, Kevin M. Huffenberger, Bradford A. Benson +128
This is a solicited whitepaper for the Snowmass 2021 community planning exercise. The paper focuses on measurements and science with the Cosmic Microwave Background (CMB). The CMB…
Analysis of Temperature-to-Polarization Leakage in BICEP3 and Keck CMB Data from 2016 to 2018
Keck Collaboration, T. St. Germaine, P. A. R. Ade +85
The BICEP/Keck Array experiment is a series of small-aperture refracting telescopes observing degree-scale Cosmic Microwave Background polarization from the South Pole in search of…
An Imprint of the Galactic Magnetic Field in the Diffuse Unpolarized Dust Emission
Brandon S. Hensley, Cheng Zhang, James J. Bock
It is well known that aligned, aspherical dust grains emit polarized radiation and that the degree of polarization depends on the angle between the interstellar magnetic field…
Characterization and Improvement of the Thermal Stability of TES Bolometers
Rita Sonka, James J. Bock, Krikor G. Megerian +3
We study the mechanism of instability in transition edge sensor (TES) bolometers used for ground based observations of the Cosmic Microwave Background (CMB) at 270GHz. The instabil…
