  • We study the physical limitations placed on cosmic microwave background (CMB) temperature and polarization measurements of the initial power spectrum. These limitations include geometric projection, acoustic physics, gravitational lensing and degeneracies with cosmological parameters. Detailed information on the spectrum is greatly assisted by polarization information and localized to the acoustic regime $k=0.02\ensuremath{-}0.2{\mathrm{Mpc}}^{\ensuremath{-}1}$ with a fundamental resolution of… CONTINUE READING
