Query: Dipole Modulation of Cosmic Microwave Background Temperature and
  Polarization   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 multipoles, exactly as in the case of
temperature. We obtain results for the case of TE, EE and BB correlations. An
anisotropic or inhomogeneous model of primordial power spectrum which leads to
such correlations in temperature field also predicts similar correlations in
CMBR polarization. We analyze the CMBR temperature and polarization data in
order to extract the signal of these correlation between l and l+1 multipoles.
Our results for the case of temperature using the latest PLANCK data agree with
those obtained by an earlier analysis. A detailed study of the correlation in
the polarization data is not possible at present. Hence we restrict ourselves
to a preliminary investigation in this case.
