The Simons Observatory: validation of reconstructed power spectra from simulated filtered maps for the small aperture telescope survey Open
We present a transfer function-based method to estimate angular power spectra from filtered maps for cosmic microwave background (CMB) surveys. This is especially relevant for experiments targeting the faint primordial gravitational wave s…

Forecasting the performance of the Minimally Informed foreground cleaning method for CMB polarization observations Open
Astrophysical foreground substraction is crucial to retrieve the cosmic microwave background (CMB) polarization out of the observed data. Recent efforts have been carried out towards the development of a minimally informed component separa…

The Simons Observatory: Combining cross-spectral foreground cleaning with multitracer -mode delensing for improved constraints on inflation Open
The Simons Observatory (SO), due to start full science operations in early 2025, aims to set tight constraints on inflationary physics by inferring the tensor-to-scalar ratio r from measurements of cosmic microwave background (CMB) polariz…

Pixel domain implementation of the Minimally Informed CMB MAp foreground\n Cleaning method Open
High fidelity separation of astrophysical foreground contributions from the\ncosmic microwave background (CMB) signal has been recognized as one of the main\nchallenges of modern CMB data analysis, and one which needs to be addressed in\na…
