Statistical isotropy of CMB anisotropy from WMAP
Tarun Souradeep, Amir Hajian
The statistical expectation values of the temperature fluctuations of cosmic microwave background (CMB) are assumed to be preserved under rotations of the sky. We investigate the s…

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 CMB and Cosmic Topology
Amir Hajian, Tarun Souradeep
The breakdown of statistical homogeneity and isotropy of cosmic perturbations is a generic feature of ultra large scale structure of the cosmos, in particular, of non trivial cosmi…
