New limit on pseudoscalar-photon mixing from WMAP Observations
Prabhakar Tiwari
The pseudoscalar-photon mixing in presence of large scale magnetic field induces polarization in light from distant cosmological sources. We study the effect of these pseudoscalars…

Polarization Alignment in JVAS/CLASS flat spectrum radio surveys
Prabhakar Tiwari, Pankaj Jain
We present a detailed statistical analysis of the alignment of polarizations of radio sources at high redshift. We use the JVAS/CLASS 8.4-GHz surveys for our study. This study is m…
