Power asymmetry in CMB polarization maps from PLANCK : a local variance analysis
Pavan K. Aluri, Arman Shafieloo
A persistent signal of power asymmetry on opposite hemispheres of CMB sky was seen in full-sky temperature measurements made so far. This asymmetry was seen in microwave sky from W…
Testing statistical Isotropy in Cosmic Microwave Background Polarization maps
Pranati K. Rath, Pramoda Kr. Samal, Srikanta Panda +2
We apply our symmetry based Power tensor technique to test conformity of PLANCK Polarization maps with statistical isotropy. On a wide range of angular scales (l=40-150), our preli…
Alignments of parity even/odd-only multipoles in CMB
Pavan K. Aluri, John P. Ralston, Amanda Weltman
We compare the statistics of parity even and odd multipoles of the cosmic microwave background (CMB) sky from PLANCK full mission temperature measurements. An excess power in odd m…
