Extending Galactic foreground emission with neural networks
Giuseppe Puglisi, Avinash Anand, Marina Migliaccio
We introduce an innovative approach employing Cycle Generative Adversarial Networks (Cycle-GANs) to accurately simulate Carbon Monoxide (CO) emissions by learning features identifi…
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…
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…
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…
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,…
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 $Î…
