The Cosmic Microwave Background Bipolar Power Spectrum: Basic Formalism and Applications
Amir Hajian, Tarun Souradeep
We study the statistical isotropy (SI) of temperature fluctuations of the CMB as distinct from Gaussianity. We present a detailed formalism of the bipolar power spectrum (BiPS) whi…

Statistical Isotropy of the Wilkinson Microwave Anisotropy Probe Data: A Bipolar Power Spectrum Analysis
Amir Hajian, Tarun Souradeep, Neil Cornish
The statistical expectation values of the temperature fluctuations of the Cosmic Microwave Background (CMB) are assumed to be preserved under rotations of the sky. We investigate t…
