Presentation Transcript

  1. Correlated Component Analysis (CCA) • Work based on Bedini et al. (Eurasip JASP 2005) • Based on the exploitation of spatial correlations between sources • Foreground frequency scaling parametrized • PhD work by Anna Bonaldi, in collaboration with Bedini, Salerno, de Zotti, …, assessing the nominal performance on Planck, and application to WMAP

  2. CCA overview

  3. CCA preliminary results

  4. CCA criticalities • Error in the estimation of the data covariance matrix needed • Different beam resolution • Map reconstruction • …
