Revealing Non-circular beam effect in WMAP-7 CMB maps with BipoSH measures of Statistical Isotropy
Nidhi Joshi, Santanu Das, Aditya Rotti +2
Mild, unavoidable deviations from circular-symmetry of instrumental beams in current Cosmic Microwave Background (CMB) experiments now pose a significant challenge to deriving high…

Statistics of Bipolar Representation of CMB maps
Nidhi Joshi, Aditya Rotti, Tarun Souradeep
Gaussianity of temperature fluctuations in the Cosmic Microwave Background(CMB) implies that the statistical properties of the temperature field can be completely characterized by…

Bipolar Harmonic encoding of CMB correlation patterns
Nidhi Joshi, Sanjay Jhingan, Tarun Souradeep +1
Deviations from statistical isotropy can be modeled in various ways, for instance, anisotropic cosmological models (Bianchi models), compact topologies and presence of primordial m…
