Post-Planck Dark Energy Constraints
Dhiraj Kumar Hazra, Subhabrata Majumdar, Supratik Pal +2
We constrain plausible dark energy models, parametrized by multiple candidate equation of state, using the recently published Cosmic Microwave Background (CMB) temperature anisotro…
Reconstruction of broad features in the primordial spectrum and inflaton potential from Planck
Dhiraj Kumar Hazra, Arman Shafieloo, George F. Smoot
With the recently published Cosmic Microwave Background data from Planck we address the optimized binning of the primordial power spectrum. As an important modification to the usua…
Test of consistency between Planck and WMAP
Dhiraj Kumar Hazra, Arman Shafieloo
Within the context of the concordance model of cosmology we test the consistency of the angular power spectrum data from WMAP and Planck looking for possible systematics. The best…
Cosmological parameter estimation with free-form primordial power spectrum
Dhiraj Kumar Hazra, Arman Shafieloo, Tarun Souradeep
Constraints on the main cosmological parameters using CMB or large scale structure data are usually based on power-law assumption of the primordial power spectrum (PPS). However, i…
