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,…
Measuring the diffuse Galactic synchrotron spectral index and curvature between 45 and 2300 MHz
Melis O. Irfan, Giuseppe Puglisi
We present an all-sky map of the synchrotron spectral index and curvature between 45 and 2300 MHz at a resolution of 1 degree calculated from a combination of numerous partial sky…
The Simons Observatory: Assessing the Impact of Dust Complexity on the Recovery of Primordial -modes
Yiqi Liu, Susanna Azzoni, Susan E. Clark +14
We investigate how dust foreground complexity can affect measurements of the tensor-to-scalar ratio, , in the context of the Simons Observatory, using a cross-spectrum component…
First release of LiteBIRD simulations from an end-to-end pipeline
M. Bortolami, N. Raffuzzi, L. Pagano +107
The LiteBIRD satellite mission aims at detecting Cosmic Microwave Background modes with unprecedented precision, targeting a total error on the tensor-to-scalar ratio of $δ…
On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe
R. Aurvik, M. Galloway, E. Gjerløw +107
We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors…
A Simulation Framework for the LiteBIRD Instruments
M. Tomasi, L. Pagano, A. Anand +111
LiteBIRD, the Lite (Light) satellite for the study of -mode polarization and Inflation from cosmic background Radiation Detection, is a space mission focused on primordial cosmo…
Requirements on bandpass resolution and measurement precision for LiteBIRD
S. Giardiello, A. Carones, T. Ghigna +95
In this work, we study the impact of an imperfect knowledge of the instrument bandpasses on the estimate of the tensor-to-scalar ratio in the context of the next-generation Lit…
Recovering the CMB signal with neural networks
J. M. Casas, L. Bonavera, J. González-Nuevo +2
Component separation is the process of extracting one or more emission sources in astrophysical maps. It is therefore crucial to develop models that can accurately clean the cosmic…
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…
Full-sky Models of Galactic Microwave Emission and Polarization at Sub-arcminute Scales for the Python Sky Model
Experiment Galactic Science Group, Julian Borrill, Susan E. Clark +15
Polarized foreground emission from the Galaxy is one of the biggest challenges facing current and upcoming cosmic microwave background (CMB) polarization experiments. We develop ne…
BrahMap: A scalable and modular map-making framework for the CMB experiments
Avinash Anand, Giuseppe Puglisi
The cosmic microwave background (CMB) experiments have reached an era of unprecedented precision and complexity. Aiming to detect the primordial B-mode polarization signal, these e…
