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…

Nearly Full-Sky Low-Multipole Cosmic Microwave Background Temperature Anisotropy: III. CMB Temperature Anomalies
Laura Herold, Graeme E. Addison, Charles L. Bennett +2
Unexpected features have been observed in the cosmic microwave background (CMB) temperature on large scales. We revisit these CMB anomalies using new foreground-cleaned CMB tempera…

Nearly Full-Sky Low-Multipole Cosmic Microwave Background Temperature Anisotropy: II. Angular Power Spectra and Likelihood
Hayley C. Nofi, Graeme E. Addison, Charles L. Bennett +2
We present a CMB temperature power spectrum measurement at large angular scales from WMAP and Planck maps that were cleaned of foregrounds using a template-based approach described…
