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…
The Simons Observatory: Development of a Pipeline to Detect Rapid Transients in Time-Ordered Data
Justin Clancy, Carlo Bacciagalupi, Josh Borrow +13
We introduce a method for detecting astrophysical transients evolving on timescales of milliseconds to minutes using cosmic microwave background (CMB) survey telescopes. While prev…
The Atacama Cosmology Telescope: Machine Learning Driven Tools for Detecting Millimeter Sources in Timestream Pre-processing
Simran K. Nerval, Erika Hornecker, Yilun Guan +14
We present a new pipeline utilizing machine learning for classifying short-duration features in raw time-ordered data (TOD) of cosmic microwave background survey observations. The…
The Atacama Cosmology Telescope: Semi-Analytic Covariance Matrices for the DR6 CMB Power Spectra
Zachary Atkins, Zack Li, David Alonso +18
The Atacama Cosmology Telescope Data Release 6 (ACT DR6) power spectrum is expected to provide state-of-the-art cosmological constraints, with an associated need for precise error…
The Simons Observatory: Combining cross-spectral foreground cleaning with multitracer -mode delensing for improved constraints on inflation
Emilie Hertig, Kevin Wolz, Toshiya Namikawa +16
The Simons Observatory (SO), due to start full science operations in early 2025, aims to set tight constraints on inflationary physics by inferring the tensor-to-scalar ratio f…
The Simons Observatory: pipeline comparison and validation for large-scale B-modes
K. Wolz, S. Azzoni, C. Hervias-Caimapo +14
The upcoming Simons Observatory Small Aperture Telescopes aim at achieving a constraint on the primordial tensor-to-scalar ratio at the level of , observi…
