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…
BICEP / Keck XVI: Characterizing Dust Polarization through Correlations with Neutral Hydrogen
Keck Collaboration, P. A. R. Ade, Z. Ahmed +92
We characterize Galactic dust filaments by correlating BICEP/Keck and Planck data with polarization templates based on neutral hydrogen (H I) observations. Dust polarization is imp…
Construction of a Large Diameter Reflective Half-Wave Plate Modulator for Millimeter Wave Applications
Joseph R. Eimer, Michael K. Brewer, David T. Chuss +14
Polarization modulation is a powerful technique to increase the stability of measurements by enabling the distinction of a polarized signal from dominant slow system drifts and unp…
Cosmology Large Angular Scale Surveyor (CLASS): Pointing Stability and Beam Measurements at 90, 150, and 220 GHz
Rahul Datta, Michael K. Brewer, Jullianna D. Couto +16
The Cosmology Large Angular Scale Surveyor (CLASS) telescope array surveys 75% of the sky from the Atacama desert in Chile at frequency bands centered near 40, 90, 150, and 220 GHz…
Design and characterization of new 90 GHz detectors for the Cosmology Large Angular Scale Surveyor (CLASS)
Carolina Núñez, John W. Appel, Sarah Marie Bruno +20
The Cosmology Large Angular Scale Surveyor (CLASS) is a polarization-sensitive telescope array located at an altitude of 5,200 m in the Chilean Atacama Desert. CLASS is designed to…
Long-Timescale Stability in CMB Observations at Multiple Frequencies using Front-End Polarization Modulation
Joseph Cleary, Rahul Datta, John W. Appel +17
The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array observing the Cosmic Microwave Background (CMB) at frequency bands centered near 40, 90, 150, and 220 GHz. C…
