Résumé : We investigate the constraining power of the CMB in the light of modern observations, focusing on the expectations from forthcoming satellite and sub-orbital (polarization oriented) experiments. In particular, we study their constraining capabilities concerning the physics of the early Universe and the onset of acceleration through the B modes polarization spectrum as a tool for inquiring primordial gravitational waves and the lensing peak.
