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…

BICEP/Keck XIX: Extremely Thin Composite Polymer Vacuum Windows for BICEP and Other High Throughput Millimeter Wave Telescopes

Keck Collaboration, P. A. R. Ade, Z. Ahmed +90

Millimeter-wave refracting telescopes targeting the degree-scale structure of the cosmic microwave background (CMB) have recently grown to diffraction-limited apertures of over 0.5…
