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…
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…
SLAC Microresonator RF (SMuRF) Electronics: A tone-tracking readout system for superconducting microwave resonator arrays
Cyndia Yu, Zeeshan Ahmed, Josef C. Frisch +22
We describe the newest generation of the SLAC Microresonator RF (SMuRF) electronics, a warm digital control and readout system for microwave-frequency resonator-based cryogenic det…
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…
A simulation suite for readout with SMuRF tone-tracking electronics
Cyndia Yu, Zeeshan Ahmed, J. Mitch D'Ewart +3
We present the details of a simulation suite for modeling the effects of readout with SLAC Microresonator RF (SMuRF) electronics. The SMuRF electronics are a warm readout and contr…
2022 Upgrade and Improved Low Frequency Camera Sensitivity for CMB Observation at the South Pole
A. Soliman, P. A. R. Ade, Z. Ahmed +83
Constraining the Galactic foregrounds with multi-frequency Cosmic Microwave Background (CMB) observations is an essential step towards ultimately reaching the sensitivity to measur…
Bandwidth and Aliasing in the Microwave SQUID Multiplexer
Cyndia Yu, Zeeshan Ahmed, Jake A. Connors +13
The microwave SQUID multiplexer (umux) has enabled higher bandwidth or higher channel counts across a wide range of experiments in particle physics, astronomy, and spectroscopy. Th…
Snowmass 2021 CMB-S4 White Paper
Kevork Abazajian, Arwa Abdulghafour, Graeme E. Addison +353
This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin a…
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…
Asteroid Measurements at Millimeter Wavelengths with the South Pole Telescope
P. M. Chichura, A. Foster, C. Patel +141
We present the first measurements of asteroids in millimeter wavelength (mm) data from the South Pole Telescope (SPT), which is used primarily to study the cosmic microwave backgro…
