Interpretation of the Global Anisotropy in the Radio Polarizations of Cosmologically Distant Sources
Pankaj Jain, S. Sarala
We present a detailed statistical study of the observed anisotropy in radio polarizations from distant extragalactic objects. This anisotropy was earlier found by Birch (1982) and…
Large Scale Alignment of Optical Polarizations from Distant QSOs using Coordinate Invariant Statistics
Pankaj Jain, Gaurav Narain, S. Sarala
We introduce several coordinate invariant statistical procedures in order to test for local alignment of polarizations. A large scale alignment of optical polarizations from distan…
Electromagnetic Polarization Effects due to Axion Photon Mixing
Pankaj Jain, Sukanta Panda, S. Sarala
We investigate the effect of axions on the polarization of electromagnetic waves as they propagate through astronomical distances. We analyze the change in the dispersion of the el…
A Circular Statistical Method for Extracting Rotation Measures
S. Sarala, Pankaj Jain
We propose a new method for the extraction of Rotation Measure from spectral polarization data. The method is based on maximum likelihood analysis and takes into account the circul…
