Fig. 4.
Radio spurs observed at frequency of 1.57 and 5.99 GHz. The colorscale represents the 1.57 GHz emission (VLA + Effelsberg). White contours correspond to the 5.99 GHz emission (VLA + Effelsberg) are at 110 μJy beam−1 × (3, 6, 12, 24, 48, 96, 192, 384). Black contours correspond to the 1.57 GHz radiation (VLA + Effelsberg) are at 140 μJy beam−1 × (3, 6, 12, 24, 48, 96, 192, 384). All data plotted have an angular resolution of 35″ FWHM. The SE-radio spur (SE), NE-radio spur (NE), and NW-radio spur (NW) have been indicated in the map. The total power map at 5.99 GHz is truncated in the southern part of the galaxy due to the primary beam.
