The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
Fast map-based simulations of systematics in CMB surveys including effects of the scanning strategy
Nialh McCallum, Daniel B. Thomas, Michael L. Brown
We present approaches to quickly simulate systematics affecting CMB observations, including the effects of the scanning strategy. Using summary properties of the scan we capture fe…
Spin-based removal of instrumental systematics in 21cm intensity mapping surveys
Nialh McCallum, Daniel B. Thomas, Philip Bull +1
Upcoming cosmological intensity mapping surveys will open new windows on the Universe, but they must first overcome a number of significant systematic effects, including polarizati…
Blind Map Level Systematics Cleaning: A Quadratic Estimator Approach
Joel Williams, Nialh McCallum, Aditya Rotti +3
We present the first detailed case study using quadratic estimators (QE) to diagnose and remove systematics present in observed Cosmic Microwave Background (CMB) maps. In this work…
Spin characterisation of systematics in CMB surveys -- a comprehensive formalism
Nialh McCallum, Daniel B. Thomas, Michael L. Brown +1
The CMB -mode polarisation signal -- both the primordial gravitational wave signature and the signal sourced by lensing -- is subject to many contaminants from systematic effect…
Controlling systematics in ground-based CMB surveys with partial boresight rotation
Daniel B. Thomas, Nialh McCallum, Michael L. Brown
Future CMB experiments will require exquisite control of systematics in order to constrain the -mode polarisation power spectrum. One class of systematics that requires careful…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
