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,…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
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…
Consequences of constant elevation scans for instrumental systematics in Cosmic Microwave Background Experiments
Daniel B. Thomas, Nialh McCallum, Michael L. Brown
Instrumental systematics need to be controlled to high precision for upcoming Cosmic Microwave Background (CMB) experiments. The level of contamination caused by these systematics…
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…
The Simons Observatory: Astro2020 Decadal Project Whitepaper
The Simons Observatory Collaboration, Maximilian H. Abitbol, Shunsuke Adachi +280
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) experiment sited on Cerro Toco in the Atacama Desert in Chile that promises to provide breakthrough…
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…
Studies of Systematic Uncertainties for Simons Observatory: Detector Array Effects
Kevin T. Crowley, Sara M. Simon, Max Silva-Feaver +36
In this proceeding, we present studies of instrumental systematic effects for the Simons Obsevatory (SO) that are associated with the detector system and its interaction with the f…
Designs for next generation CMB survey strategies from Chile
Jason R. Stevens, Neil Goeckner-Wald, Reijo Keskitalo +20
New telescopes are being built to measure the Cosmic Microwave Background (CMB) with unprecedented sensitivity, including Simons Observatory (SO), CCAT-prime, the BICEP Array, SPT-…
The Simons Observatory: Instrument Overview
Nicholas Galitzki, Aamir Ali, Kam S. Arnold +75
The Simons Observatory (SO) will make precise temperature and polarization measurements of the cosmic microwave background (CMB) using a set of telescopes which will cover angular…
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…
