Cosmic Microwave Background Polarimetry : stakes and challenges

A. Ghribi (GANIL)

11h GANIL seminar room (105)

a coffee will be served 15mn before

 

One of the last missing pieces of the standard model of cosmology is the proof of inflation ; a very accelerated phase of expansion of our Universe. An indirect way to confirm it is the precise measurement (and detection) of the so called B-modes polarisation of the Cosmic Microwave Background ; imprint of the primordial gravitational waves. This seminar focuses on some of the technical challenges that the post Planck-HFI community faces today for the detection of the Holy Graal of modern cosmology.
