Optical modeling of systematic uncertainties in detector polarization angles for the Atacama Cosmology Telescope

Jun 24, 2024 | opg.optica.org | Michael D. Niemack |Jeff McMahon |Rahul Datta |Mark Devlin

We present an estimate of the Atacama Cosmology Telescope (ACT)detector polarization angle systematic uncertainty from opticsperturbation analysis using polarization-sensitive ray tracing in CODEV optical design software. Uncertainties in polarization anglecalibration in CMB measurements can limit constraints on cosmicbirefringence and other cosmological parameters sensitive topolarization leakage.
