High-accuracy polarimetry for CMB: new frontiers with the POLOCALC project
A. Novelli, F. Astori, L. Bizzarri +8
Modern telescopes observing the Cosmic Microwave Background (CMB) polarization require an exquisite control of systematics to target Inflationary Gravitational Waves (IGW), Cosmic…
Robust CMB B-mode analysis with Needlet-ILC and simulation-based inference
Adriaan J. Duivenvoorden, Kristen Surrao, Adrian E. Bayer +4
We explore a novel analysis framework for parameter inference with large-scale CMB polarization data. Our method uses simulation-based inference combined with the needlet internal…
The Simons Observatory: Quantifying the impact of beam chromaticity on large-scale B-mode science
Nadia Dachlythra, Kevin Wolz, Susanna Azzoni +17
The Simons Observatory (SO) Small Aperture Telescopes (SATs) will observe the Cosmic Microwave Background (CMB) temperature and polarization at six frequency bands. Within these ba…
Impact of half-wave plate systematics on the measurement of cosmic birefringence from CMB polarization
Marta Monelli, Eiichiro Komatsu, Alexandre E. Adler +6
Polarization of the cosmic microwave background (CMB) can probe new parity-violating physics such as cosmic birefringence (CB), which requires exquisite control over instrumental s…
Probing frequency-dependent half-wave plate systematics for CMB experiments with full-sky beam convolution simulations
Adriaan J. Duivenvoorden, Alexandre E. Adler, Matteo Billi +2
We study systematic effects from half-wave plates (HWPs) for cosmic microwave background (CMB) experiments using full-sky time-domain beam convolution simulations. Using an optical…
Statistics of CMB polarization angles
James Creswell, Nadia Dachlythra, Hao Liu +2
We study the distribution functions of the CMB polarization angle , focusing on the Planck 2018 CMB maps. We extend the model of Preece & Battye (2014) of Gaussian correlated $Q…
