  • Probing features in inflaton potential and reionization history with future CMB space observations 
    Hazra, Dhiraj Kumar; Paoletti, Daniela; Ballardini, Mario; Finelli, Fabio; Shafieloo, Arman; Smoot, George F; Starobinsky, Alexei A. (NURIS; Energetic Cosmos Laboratory, 2018-03-04)
    We consider the prospects of probing features in the primordial power spectrum with future Cosmic Microwave Background (CMB) polarization measurements. In the scope of the inflationary scenario, such features in the spectrum ...
  • Witnessing the reionization history using Cosmic Microwave Background observation from Planck 
    Hazra, Dhiraj Kumar; Smoot, George F. (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2017-08-16)
    We constrain the history of reionization using the data from Planck 2015 Cosmic Microwave Background (CMB) temperature and polarization anisotropy observations. We also use prior constraints on the reionization history at ...
