摘要Scattering of cosmic microwave background (CMB) radiation in galaxy clusters induces
polarization signals determined by the quadrupole anisotropy in the photon
distribution at the location of clusters. This ”remote quadrupole” derived from the
measurements of the induced polarization in galaxy clusters provides an opportunity
of reconstruction of local CMB temperature anisotropies. In this Letter we develop an
algorithm of the reconstruction through the estimation of the underlying primordial
gravitational potential, which is the origin of the CMB temperature and polarization
fluctuations and CMB induced polarization in galaxy clusters. We found a nice reconstruction
for the quadrupole and octopole components of the CMB temperature
anisotropies with the assistance of the CMB induced polarization signals. The reconstruction
can be an important consistency test on the puzzles of CMB anomaly,
especially for the low quadrupole and axis of evil problems reported in WMAP and
Planck data.
