CLASS Data Pipeline and Maps for 40 GHz Observations through 2022
Yunyang Li, Joseph Eimer, Keisuke Osumi +33
The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background over 75\% of the sky from the Atacama Desert, Chile, at freque…
Calibration of Transition-edge Sensor (TES) Bolometer Arrays with Application to CLASS
John W. Appel, Charles L. Bennett, Michael K. Brewer +24
The current and future cosmic microwave background (CMB) experiments fielding kilo-pixel arrays of transition-edge sensor (TES) bolometers require accurate and robust gain calibrat…
Four-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: On-sky Receiver Performance at 40, 90, 150, and 220 GHz Frequency Bands
Sumit Dahal, John W. Appel, Rahul Datta +37
The Cosmology Large Angular Scale Surveyor (CLASS) observes the polarized cosmic microwave background (CMB) over the angular scales of 1 90 with the…
Limits on Polarized Dust Spectral Index Variations for CMB Foreground Analysis
Keisuke Osumi, Janet L. Weiland, Graeme E. Addison +1
Using Planck polarization data, we search for and constrain spatial variations of the polarized dust foreground for cosmic microwave background (CMB) observations, specifically in…

Kathleen Harrington, Rahul Datta, Keisuke Osumi +33
The Cosmology Large Angular Scale Surveyor (CLASS) is a four-telescope array observing the largest angular scales () of the cosmic microwave backgroun…
Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: 40 GHz Telescope Pointing, Beam Profile, Window Function, and Polarization Performance
Zhilei Xu, Michael K. Brewer, Pedro Fluxá Rojas +33
The Cosmology Large Angular Scale Surveyor (CLASS) is a telescope array that observes the cosmic microwave background (CMB) over 75% of the sky from the Atacama Desert, Chile, at f…
Effect of Template Uncertainties on the WMAP and Planck Measures of the Optical Depth Due To Reionization
J. L. Weiland, K. Osumi, G. E. Addison +4
The reionization optical depth is the most poorly determined of the six CDM parameters fit to CMB anisotropy data. Instrumental noise and systematics have prevented uncertaintie…
Robust New Statistic for fitting the Baryon Acoustic Feature
Keisuke Osumi, Shirley Ho, Daniel J. Eisenstein +1
We investigate the utility and robustness of a new statistic, , for analyzing Baryon Acoustic Oscillations (BAO). We apply ,…
