A close examination of CMB mirror-parity

Assaf Ben-David, Ely D. Kovetz

Research output: Contribution to journalArticlepeer-review


We revisit recent claims of significant mirror-parity in CMB data from WMAP and Planck with a careful analysis using statistical estimators in both harmonic and pixel spaces. While the data indeed show significant signs of odd mirror-parity under some circumstances, the broad study shows that the results are not in significant tension with ΛCDM.
