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…
The cross correlation of the ABS and ACT maps
Zack Li, Sigurd Naess, Simone Aiola +29
One of the most important checks for systematic errors in CMB studies is the cross correlation of maps made by independent experiments. In this paper we report on the cross correla…
Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: A Measurement of Circular Polarization at 40 GHz
Ivan L. Padilla, Joseph R. Eimer, Yunyang Li +32
We report circular polarization measurements from the first two years of observation with the 40 GHz polarimeter of the Cosmology Large Angular Scale Surveyor (CLASS). CLASS is con…
Results from the Atacama B-mode Search (ABS) Experiment
Akito Kusaka, John Appel, Thomas Essinger-Hileman +25
The Atacama B-mode Search (ABS) is an experiment designed to measure cosmic microwave background (CMB) polarization at large angular scales (). It operated from the ACT si…
A Projected Estimate of the Reionization Optical Depth Using the CLASS Experiment's Sample-Variance Limited E-Mode Measurement
Duncan J. Watts, Bingjie Wang, Aamir Ali +17
We analyze simulated maps of the Cosmology Large Angular Scale Surveyor (CLASS) experiment and recover a nearly cosmic-variance limited estimate of the reionization optical depth $…
The Atacama Cosmology Telescope: Cosmological parameters from three seasons of data
Jonathan L. Sievers, Renée A. Hlozek, Michael R. Nolta +90
We present constraints on cosmological and astrophysical parameters from high-resolution microwave background maps at 148 GHz and 218 GHz made by the Atacama Cosmology Telescope (A…
