The filamentary radio lobes of the Seyfert-Starburst composite galaxy
  NGC3079
  We present results from multi-frequency polarization-sensitive Very Large
Array observations of the Seyfert-starburst composite galaxy NGC3079. Our
sensitive radio observations reveal a plethora of radio filaments comprising
the radio lobes in this galaxy. We analyze the origin of these radio filaments
in the context of existing Chandra X-ray and HST emission-line data. We do not
find a one-to-one correlation of the radio filaments with the emission line
filaments. The north-eastern lobe is highly polarized with polarization
fractions $\sim$33% at 5 GHz. The magnetic fields are aligned with the linear
extents of the optically-thin filaments, as observed in our, as well as other
observations in the literature. Our rotation measure images show evidence for
rotation measure inversion in the north-eastern lobe. Our data best fit a model
where the cosmic rays follow the magnetic field lines generated as a result of
the dynamo mechanism. There could be additional effects like shock acceleration
that might also be playing a role. We speculate that the peculiar radio lobe
morphology is a result of an interplay between both the superwinds and the AGN
jet that are present in the galaxy. The jet, in fact, might be playing a major
role in providing the relativistic electron population that is present in the
radio lobes.
