Development and characterization of a millimeter-wave circular polarization observation method using a quarter-wave plate with Simons Array
Kana Sakaguri, Darcy R. Barron, Yuji Chinone +17
We have developed and demonstrated a method for measuring circular polarization at 90 GHz by combining a quarter-wave plate (QWP) and a continuously rotating half-wave plate (HWP).…
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…
Feedback-Controlled Beam Pattern Measurement Method Using a Power-Variable Calibration Source for Cosmic Microwave Background Telescopes
Haruaki Hirose, Masaya Hasegawa, Daisuke Kaneko +5
We demonstrate a novel beam pattern measurement method for the side lobe characterization of cosmic microwave background telescopes. The method employs a power-variable artificial…
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…
A Method of Measuring TES Complex ETF Response in Frequency-domain Multiplexed Readout by Single Sideband Power Modulation
Yu Zhou, Tijmen de Haan, Hiroki Akamatsu +5
The digital frequency domain multiplexing (DfMux) technique is widely used for astrophysical instruments with large detector arrays. Detailed detector characterization is required…
Exploration of the polarization angle variability of the Crab Nebula with POLARBEAR and its application to the search for axion-like particles
Shunsuke Adachi, Tylor Adkins, Carlo Baccigalupi +23
The Crab Nebula, also known as Tau A, is a polarized astronomical source at millimeter wavelengths. It has been used as a stable light source for polarization angle calibration in…
