Alignments in quasar polarizations: pseudoscalar-photon mixing in the presence of correlated magnetic fields
Nishant Agarwal, Archana Kamal, Pankaj Jain
We investigate the effects of pseudoscalar-photon mixing on electromagnetic radiation in the presence of correlated extragalactic magnetic fields. We model the Universe as a collec…

Signatures of Pseudoscalar Photon Mixing in CMB Radiation
Nishant Agarwal, Pankaj Jain, Douglas W. McKay +1
We model the effect of photon and ultra-light pseudoscalar mixing on the propagation of electromagnetic radiation through the extragalactic medium. The medium is modelled as a larg…
