A minimal power-spectrum-based moment expansion for CMB B-mode searches
S. Azzoni, M. H. Abitbol, D. Alonso +3
The characterization and modeling of polarized foregrounds has become a critical issue in the quest for primordial -modes. A typical method to proceed is to factorize and parame…

Simulated multi-tracer analyses with HI intensity mapping
Amadeus Witzemann, David Alonso, José Fonseca +1
We use full sky simulations, including the effects of foreground contamination and removal, to explore multi-tracer synergies between a SKA-like 21cm intensity mapping survey and a…
