| Abstract: |
NGC 3079 is unique amongst spiral galaxies in that it has a compact VLBI radio core as well as very well-defined radio lobes on kpc-scales. The radio emission has a double-lobed appearance (reminiscent of the more powerful ellipticals on much larger scales) and the lobes are clearly out of the plane in this edge-on system. Since there is also a nuclear starburst and a 'bubble' of H-alpha emission, this galaxy provides a nearby laboratory for the study of the relationship between AGNs and starbursts. We here present observations at 327 MHz and 610 MHz of this system using the new Giant Metre-Wave Radio Telescope in India, showing that the radio emission extends to much larger scales than previously observed. A comparison with selected images at other wavebands will also be presented. |
