Improved Constraints on Cosmic Microwave Background Circular Polarization with CLASS
Thomas Essinger-Hileman, Caleigh Ryan, Yunyang Li +25
We present improved constraints on circular polarization in the cosmic microwave background (CMB) from the Cosmology Large Angular Scale Surveyor (CLASS) experiment using data at 9…
A Measurement of the Largest-Scale CMB E-mode Polarization with CLASS
Yunyang Li, Joseph Eimer, John Appel +34
We present measurements of large-scale cosmic microwave background (CMB) E-mode polarization from the Cosmology Large Angular Scale Surveyor (CLASS) 90 GHz data. Using 115 det-yr o…
High-Efficiency and Low-Noise Detectors for the Upgraded CLASS 90 GHz Focal Plane
Carolina Núñez, John W. Appel, Rahul Datta +22
We present the in-lab and on-sky performance for the upgraded 90 GHz focal plane of the Cosmology Large Angular Scale Surveyor (CLASS), which had four of its seven detector wafers…
The Atacama Cosmology Telescope: Quantifying Atmospheric Emission above Cerro Toco
Thomas W. Morris, Elia Battistelli, Ricardo Bustos +17
At frequencies below 1 Hz, fluctuations in atmospheric emission in the Chajnantor region in northern Chile are the primary source of interference for bolometric millimeter-wave obs…
Sensitivity-Improved Polarization Maps at 40 GHz with CLASS and WMAP data
Rui Shi, John W. Appel, Charles L. Bennett +18
Improved polarization measurements at frequencies below 70 GHz with degree-level angular resolution are crucial for advancing our understanding of the Galactic synchrotron radiatio…
CLASS Observations of Atmospheric Cloud Polarization at Millimeter Wavelengths
Yunyang Li, John W. Appel, Charles L. Bennett +21
The dynamic atmosphere imposes challenges to ground-based cosmic microwave background observation, especially for measurements on large angular scales. The hydrometeors in the atmo…
CLASS Angular Power Spectra and Map-Component Analysis for 40 GHz Observations through 2022
Joseph R. Eimer, Yunyang Li, Michael K. Brewer +31
Measurement of the largest angular scale () features of the cosmic microwave background (CMB) polarization is a powerful way to constrain the optical depth to reionizati…
