BICEP/Keck XXII: Analysis of the South Pole Atmosphere for CMB Observations

P. A. R. Ade, Z. Ahmed, M. Amiri +92

The South Pole is among the driest sites on Earth, and the resulting high atmospheric transparency makes it an excellent site for millimeter-wave astronomical observations. Neverth…

Status of BICEP Array and Integration of the 220/270 GHz Receiver

A. Steiger, P. A. R. Ade, Z. Ahmed +83

Measurements of the polarization of the cosmic microwave background are critical for modern cosmology as they constrain the physics of the early universe and cosmic inflation. BICE…

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…

BICEP / Keck XVII: Line of Sight Distortion Analysis: Estimates of Gravitational Lensing, Anisotropic Cosmic Birefringence, Patchy Reionization, and Systematic Errors

Keck Collaboration, P. A. R. Ade, Z. Ahmed +91

We present estimates of line-of-sight distortion fields derived from the 95 GHz and 150 GHz data taken by BICEP2, BICEP3, and Keck Array up to the 2018 observing season, leading to…
