The Simons Observatory: Detector Polarization Angle Calibration using Sparse Wire Grid with Initial Data Sets of the Small Aperture Telescope
Hironobu Nakata, Shunsuke Adachi, Kyohei Yamada +22
Improved measurements of -modes in the cosmic microwave background can be obtained through accurate calibration of the orientation of detector antennas as projected onto the sky…
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…
Simons Observatory: Observatory Scheduler and Automated Data Processing
Yilun Guan, Kathleen Harrington, Jack Lashner +11
The Simons Observatory (SO) is a next-generation ground-based telescope located in the Atacama Desert in Chile, designed to map the cosmic microwave background (CMB) with unprecede…
The Simons Observatory: Design, integration, and testing of the small aperture telescopes
Nicholas Galitzki, Tran Tsan, Jake Spisak +77
The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment that includes small-aperture telescopes (SATs) observing from an altitude of 5,200 m in the Ata…
The Simons Observatory: Beam characterization for the Small Aperture Telescopes
Nadia Dachlythra, Adriaan J. Duivenvoorden, Jon E. Gudmundsson +27
We use time-domain simulations of Jupiter observations to test and develop a beam reconstruction pipeline for the Simons Observatory Small Aperture Telescopes. The method relies on…
