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…

SPT-3G+: A Cosmic Microwave Background Experiment for the South Pole Telescope

T. Natoli, Z. Ahmed, H. Athreya +72

SPT-3G+ is the next survey receiver planned to be installed in early 2029 on the 10-meter South Pole Telescope (SPT). This new receiver will feature 6,020 polarization-sensitive di…

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…
