Stokes parameters spectral distortions due to the Sunyaev-Zel'dovich
  effect and an independent estimation of the CMB low multipoles
  We consider the Stokes parameters' frequency spectral distortions arising due
to Compton scattering of the anisotropic cosmic microwave background (CMB)
radiation, the Sunyaev-Zel' dovich effect (SZ), towards clusters of galaxies.
We single out a very special type of such distortions and find simple
analytical formulas for them. We show that this kind of distortion has a very
distinctive spectral shape and can be separated from other kinds of
contaminants. We demonstrate that this effect gives us an opportunity for an
independent estimation of the low-multipole angular CMB anisotropies, such as
the dipole, the quadrupole, and the octupole. We also show that, using
distorted signals from nearby and distant clusters, one can distinguish between
the Sachs-Wolfe and the integrated Sachs-Wolfe effects. The detection of such
distortions can be feasible with high-angular resolution and high-sensitivity
space missions, such as the upcoming Millimetron Space Observatory experiment.
