Improved Absolute Polarization Calibrator for BICEP CMB Polarimeters
A. R. Polish, P. A. R. Ade, Z. Ahmed +89
Cosmic birefringence is a hypothesized parity violation in electromagnetism that predicts a frequency-independent polarization rotation as light propagates. This would rotate the l…

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…

Development of the 220/270 GHz Receiver of BICEP Array
Keck Collaboration, Y. Nakato, P. A. R. Ade +82
Measurements of B-mode polarization in the CMB sourced from primordial gravitational waves would provide information on the energy scale of inflation and its potential form. To ach…
