Suppressing CMB low multipoles with ISW effect
Santanu Das, Tarun Souradeep
Recent results of Planck data reveal that the power in the low multipoles of the CMB angular power spectrum, approximately up to , is significantly lower than the theoretical…

Leakage of power from dipole to higher multipoles due to non-symmetric WMAP beam
Santanu Das, Tarun Souradeep
A number of studies of WMAP and Planck claimed the low multipole (specially quadrupole) power deficiency in CMB power spectrum. Anomaly in the orientations of the low multipoles ha…
