Forecasting the performance of the Minimally Informed foreground cleaning method for CMB polarization observations
Clément Leloup, Magdy Morshed, Arianna Rizzieri
Astrophysical foreground substraction is crucial to retrieve the cosmic microwave background (CMB) polarization out of the observed data. Recent efforts have been carried out towar…

Pixel domain implementation of the Minimally Informed CMB MAp foreground Cleaning method
Magdy Morshed, Arianna Rizzieri, Clément Leloup +2
High fidelity separation of astrophysical foreground contributions from the cosmic microwave background (CMB) signal has been recognized as one of the main challenges of modern CMB…
