Primordial power spectrum from Planck
If you have a question about this talk, please contact ma557.
Using modified Richardson-Lucy algorithm I shall demonstrate the reconstruction of the primordial power spectrum using the Cosmic Microwave Background temperature anisotropy data from Planck. I shall highlight the significant features in the primordial power spectrum through a proper error estimation. I shall also address the consistency of the primordial power spectrum reconstructed from Planck angular power spectrum in different frequency channels with WMAP -9 angular power spectrum data. I shall explore the degeneracy between primordial power spectrum features and the effects of CMB lensing. Towards the end I shall present two nearly smooth primordial power spectra, containing only the important features that provide significant improvement in fit to the Planck data compared to power law primordial power spectrum.
