dc.description.abstractResults of the AGN jets position angle alignments in the ELAIS N1 Deep radio survey are presented here. The ELAIS N1 deep radio survey was carried out with the Giant Meter- wave Radio Telescope at 615 MHz. The deep field is a seven pointing mosaic that covers 1.2 sq.deg centred at α2000 = 16h10m35s and δ2000 = 54d35′ with an average angular resolution of 5” × 5” across the mosaic. The average sensitivity of the mosaicked image is 10μJy/beam in Stokes I. There were 65 extended radio galaxy jets extracted from the image of which 33 galaxies have redshift information available. The positions angles of radio galaxy jets are expected to be uniform. The radio galaxy jets in our sample were found to deviate from uniform distribution of positions angles to 99 percent significance level. Further testing with angular covariance reveals alignments in radio position angles, across angular scales of 1.2 to 1.8 à. Position angle correlations at scales of 1.2 to 1.8 translates to a comoving scale of 50-75 Mpc/h at z = 1. These results corroborate prior evidence for large scale alignments in quasar optical polarization derived by Hutsem ́ekers (1998).en_US
