Imprint of Inhomogeneous and Anisotropic Primordial Power Spectrum on CMB Polarization
Monthly Notices of the Royal Astronomical Society(2016)
Abstract
We consider an inhomogeneous model and independently an anisotropic model of primordial power spectrum in order to describe the observed hemispherical anisotropy in cosmic microwave background radiation (CMBR). This anisotropy can be parametrized in terms of the dipole modulation model of the temperature field. Both the models lead to correlations between spherical harmonic coefficients correspond...
