Dipole Modulation in Tensor Modes: Signatures in CMB Polarization

Year: 2014

Type: preprint

Abstract: In this work we consider a dipole asymmetry in tensor modes and study the effects of this asymmetry on the angular power spectra of CMB. We derive analytical expressions for the $C_{l}^{TT}$ and $C_{l}^{BB}$ in the presence of such dipole modulation in tensor modes for $l<100$. We also discuss on the amplitude of modulation term and show that the $C_{l}^{BB}$ is considerably modified due to this term.
