Expected dipole asymmetry in CMB polarization
M. H. Namjoo, A. A. Abolhasani, H. Assadullahi +3
We explore the hemispherical asymmetry predicted in cosmic microwave background polarization when there is an asymmetry in temperature anisotropies due to primordial perturbations.…
CMB Hemispherical Asymmetry: Long Mode Modulation and non-Gaussianity
Mohammad Hossein Namjoo, Ali Akbar Abolhasani, Shant Baghram +1
The observed hemispherical asymmetry in CMB map can be explained by modulation from a long wavelength super horizon mode which non-linearly couples to the CMB modes. We address the…
No Large Scale Curvature Perturbations during Waterfall of Hybrid Inflation
Ali Akbar Abolhasani, Hassan Firouzjahi
In this paper the possibility of generating large scale curvature perturbations induced from the entropic perturbations during the waterfall phase transition of standard hybrid inf…
