Blind foreground subtraction for intensity mapping experiments

30 Sep 2014 David Alonso Philip Bull Pedro G. Ferreira Mario G. Santos

We make use of a large set of fast simulations of an intensity mapping experiment with characteristics similar to those expected of the Square Kilometre Array (SKA) in order to study the viability and limits of blind foreground subtraction techniques. In particular, we consider different approaches: polynomial fitting, principal component analysis (PCA) and independent component analysis (ICA)... (read more)
