Detectors for CLASS-W2: The second 90 GHz telescope of the Cosmology Large Angular Scale Surveyor
John W. Appel, Kyuyoung Bae, Charles L. Bennett +26
The Cosmology Large Angular Scale Surveyor (CLASS) is measuring the Cosmic Microwave Background (CMB) polarization anisotropy on the largest angular scales (>1 degree) to probe the…
Diamond-loaded polyimide aerogel scattering filters and their applications in astrophysical and planetary science observations
Kyle R. Helson, Carol Yan Yan Chan, Stefan Arseneau +9
Infrared-blocking, aerogel-based scattering filters have a broad range of potential applications in astrophysics and planetary science instruments in the far-infrared, sub-millimet…
Spectral Characterization of a 90 GHz CLASS Pixel
Gregory Jaehnig, John Appel, Sarah Marie Bruno +10
The Cosmology Large Angular Scale Surveyor (CLASS) is an experiment designed to measure the polarization of the cosmic microwave background on large angular scales to probe cosmic…
A flux-limited sample of dusty star-forming galaxies from the Atacama Cosmology Telescope: physical properties and the case for multiplicity
Kirsten R. Hall, Jake Hassan, Richard M. Feder +3
We report the modeling of the millimeter and far-infrared spectral energy distributions of 71 dusty star-forming galaxies (DSFGs) selected by the Atacama Cosmology Telescope (ACT)…
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…
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…
