A cm-wave quantum noise limited resonant superconducting parametric amplifier
V. Gilles, T. Sweetnam, B. Mohammadian +2
Superconducting Parametric Amplifiers (SPAs) have seen great interest in recent years due to their high gain and quantum limited noise performance. Among these amplifiers, resonant…

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…

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…
