Polarization Alignment in JVAS/CLASS flat spectrum radio surveys

Understand

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 motivated by the puzzling signal of alignment of polarizations from distant quasars at optical frequencies.
• We explore several different cuts on the polarization flux for our analysis.
