Dipole Modulation of Cosmic Microwave Background Temperature and Polarization
Shamik Ghosh, Rahul Kothari, Pankaj Jain +1
We propose a dipole modulation model for the Cosmic Microwave Background Radiation (CMBR) polarization field. We show that the model leads to correlations between l and l+1 multipo…
Imprint of Inhomogeneous and Anisotropic Primordial Power Spectrum on CMB Polarization
Rahul Kothari, Shamik Ghosh, Pranati K. Rath +2
We consider an inhomogeneous model and independently an anisotropic model of primordial power spectrum in order to describe the observed hemispherical anisotropy in Cosmic Microwav…
Cosmological Power Spectrum in Non-commutative Space-time
Rahul Kothari, Pranati K. Rath, Pankaj Jain
We propose a generalized star product which deviates from the standard product when the fields at evaluated at different space-time points. This produces no changes in the standard…
