Probing features in the primordial perturbation spectrum with large-scale structure data
Benjamin L'Huillier, Arman Shafieloo, Dhiraj Kumar Hazra +2
The form of the primordial power spectrum (PPS) of cosmological scalar (matter density) perturbations is not yet constrained satisfactorily in spite of the tremendous amount of inf…
Probing features in inflaton potential and reionization history with future CMB space observations
Dhiraj Kumar Hazra, Daniela Paoletti, Mario Ballardini +4
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 inflatio…
Witnessing the reionization history using Cosmic Microwave Background observation from Planck
Dhiraj Kumar Hazra, George F. Smoot
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 c…
