SUMMARY:CMB polarisation: challenging but worth it - Agnes Ferte (UcL)

DESCRIPTION:In this talk\, I will present the wealth of information on the
  universe contained in CMB polarisation. However\, many difficulties arise
  when trying to access this valuable information from observations. I will
  present one of the most important of these issues concerning its power sp
 ectrum estimation from maps and a way to solve it. In a second part\, I wi
 ll present forecasts on the estimation of the tensor-to-scalar ratio — w
 hich gives the energy scale of the cosmic inflation — from future CMB po
 larisation observations as well as on the detection of a breaking of parit
 y in the gravitational sector in the primordial universe. I will finish by
  presenting current work on the impact of Faraday rotation on the CMB pola
 risation.
