Isotropy-violation tests and turbulence for CMB B-mode foregrounds

ORAL

Abstract

Isotropy-violation tests can be used to assess the level of foreground contamination along different lines of sight. First application of an isotropy-violation test on Planck 353 GHz B-mode polarization data indicated a potential foreground source in the BICEP patch. We also discuss ongoing efforts to characterize the polarization properties of galactic dust via hydrodynamical simulations.
