Measurement and Modeling of Polarized Atmosphere at the South Pole with SPT-3G
A. Coerver, J. A. Zebrowski, S. Takakura +102
We present the detection and characterization of fluctuations in linearly polarized emission from the atmosphere above the South Pole. These measurements make use of data from the…
A measurement of atmospheric circular polarization with POLARBEAR
Takuro Fujino, Satoru Takakura, Shahed Shayan Arani +20
At millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth's magnetic field. We report a measurement…
The European Low Frequency Survey on the Simons Array
Aniello Mennella, Kam Arnold, Susanna Azzoni +18
In this paper we present the European Low Frequency Survey (ELFS), a project that will enable foregrounds-free measurements of the primordial -mode polarization and a detection…
Calibration of detector time constant with a thermal source for the POLARBEAR-2A CMB polarization experiment
S. Takatori, M. Hasegawa, M. Hazumi +22
The Simons Array (SA) project is a ground-based Cosmic Microwave Background (CMB) polarization experiment. The SA observes the sky using three telescopes, and POLARBEAR-2A (PB-2A)…
