Polarized wavelets and curvelets on the sphere

Understand

The statistics of the temperature anisotropies in the primordial cosmic microwave background radiation field provide a wealth of information for cosmology and for estimating cosmological parameters.

• An even more acute inference should stem from the study of maps of the polarization state of the CMB radiation.
• Measuring the extremely weak CMB polarization signal requires very sensitive instruments.
• The full-sky maps of both temperature and polarization anisotropies of the CMB to be delivered by the upcoming Planck Surveyor satellite experiment are hence being awaited with excitement.
