Revealing the Unusual Structure of the KAT-7-Discovered Giant Radio
  Galaxy J0133$-$1302
  We present a new study of the 1.7 Mpc KAT-7-discovered giant radio galaxy,
J0133$-$1302, which was carried out using GMRT data at 323 and 608 MHz. This
source is located at RA $01^h33^m13^s$ and Dec
$-13^{\circ}03^\prime00^{\prime\prime}$ and has a photometric redshift of
$\sim$0.3. We discovered unusual morphological properties of the source which
include lobes that are exceptionally asymmetric, where the upper lobe is much
further from the core when compared to the lower lobe, and a complex structure
of the upper lobe. This complex structure of the upper lobe hints at the
presence of another source, in close proximity to the edge of the lobe, which
resembles a bent-double, or distorted bent tail (DBT) radio galaxy. Both the
upper lobe and the lower lobe have a steep spectrum, and the synchrotron age of
the lower lobe should be less than about 44 Myr. The core has an inverted
spectrum, and our results suggest that the parent galaxy in J0133$-$1302 is
starting a new jet activity. Our spectral analysis indicates that this source
could be a GigaHertz Peaked Spectrum (GPS) radio galaxy.
