Characterizing bias on large scale CMB -modes after galactic foregrounds cleaning
Josquin Errard, Radek Stompor
We study the performance of a typical near-future full sky CMB space mission, aiming at the characterization of the large scale -modes polarization anisotropies with precision o…
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…
Solving linear equations with messenger-field and conjugate gradients techniques - an application to CMB data analysis
J. Papez, L. Grigori, R. Stompor
We discuss linear system solvers invoking a messenger-field and compare them with (preconditioned) conjugate gradients approaches. We show that the messenger-field techniques corre…
Iterative map-making with two-level preconditioning for polarized Cosmic Microwave Background data sets
Giuseppe Puglisi, Davide Poletti, Giulio Fabbian +3
An estimation of the sky signal from streams of Time Ordered Data (TOD) acquired by Cosmic Microwave Background (\cmb) experiments is one of the most important steps in the context…
The LiteBIRD Satellite Mission - Sub-Kelvin Instrument
A. Suzuki, P. A. R. Ade, Y. Akiba +149
Inflation is the leading theory of the first instant of the universe. Inflation, which postulates that the universe underwent a period of rapid expansion an instant after its birth…
