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…
Constraints on the polarization angle oscillations of the Crab Nebula with the Simons Array and its applications to the search for axion-like particles
Tylor Adkins, Shahed Shayan Arani, Kam Arnold +27
We present a search for polarization oscillation of the Crab Nebula, also known as Tau A, at millimeter wavelengths using observations with the Simons Array, the successor experime…
Addressing Synchrotron Challenges for CMB Observations: ELFS-SA Collaboration for Robust Foreground Removal
E. de la Hoz, A. Mennella, K. Arnold +17
Upcoming cosmic microwave background (CMB) experiments aim to detect primordial gravitational waves with unprecedented sensitivity. Effective foreground removal is essential to avo…
The Simons Observatory: Large Diameter and Large Load-Capacity Superconducting Magnetic Bearing for a Millimeter-Wave Polarization Modulator
Daichi Sasaki, Junna Sugiyama, Kyohei Yamada +5
We present the design methodology and characterization of a superconducting magnetic bearing (SMB) system for the polarization modulator in the SAT-LF, one of the small aperture te…
The Simons Observatory: Validation of reconstructed power spectra from simulated filtered maps for the Small Aperture Telescope survey
Carlos Hervías-Caimapo, Kevin Wolz, Adrien La Posta +33
We present a transfer function-based method to estimate angular power spectra from filtered maps for cosmic microwave background (CMB) surveys. This is especially relevant for expe…
