Consistency of the Planck CMB data and CDM cosmology
Arman Shafieloo, Dhiraj Kumar Hazra
We test the consistency between Planck temperature and polarization power spectra and the concordance model of Cold Dark Matter cosmology (CDM) within the framework of Cross…
Metastable Dark Energy with Radioactive-like Decay
Arman Shafieloo, Dhiraj Kumar Hazra, Varun Sahni +1
We propose a new class of metastable dark energy (DE) phenomenological models in which the DE decay rate does not depend on external parameters such as the scale factor or the curv…
Primordial features and Planck polarization
Dhiraj Kumar Hazra, Arman Shafieloo, George F. Smoot +1
With the Planck 2015 Cosmic Microwave Background (CMB) temperature and polarization data, we search for possible features in the primordial power spectrum (PPS). We revisit the Wig…
