Description
I will present three applications of FURAX, a JAX-powered, open-source framework designed for modular and efficient CMB data analysis. First, I will discuss mapmaking—the conversion of time-ordered data into sky maps—with an emphasis on strategies to mitigate systematic effects. Second, I will show how FURAX enables robust component separation in the map domain, extracting CMB signals from sky maps while accounting for the spatial variability of foreground contaminants. Finally, I will demonstrate how to use FURAX to perform time-domain component separation by reconstructing atmospheric emission maps from CMB observations. The talk will be accompanied by tutorial notebooks to support hands-on exploration.
