Maximum Likelihood algorithm for parametric component separation in CMB experiments
R. Stompor, S. Leach, F. Stivoli +1
We discuss an approach to the component separation of microwave, multi-frequency sky maps as those typically produced from Cosmic Microwave Background (CMB) Anisotropy data sets. T…

Coupled and Extended Quintessence: theoretical differences and structure formation
Valeria Pettorino, Carlo Baccigalupi
The case of a coupling between dark energy and matter (Coupled Quintessence) or gravity (Extended Quintessence) has recently attracted a deep interest and has been widely investiga…

WMAP 3yr data with the CCA: anomalous emission and impact of component separation on the CMB power spectrum
A. Bonaldi, S. Ricciardi, S. Leach +3
The Correlated Component Analysis (CCA) allows us to estimate how the different diffuse emissions mix in CMB experiments, exploiting also complementary information from other surve…
