About this Image

NGC6764 is a nearby Seyfert galaxy. The supermassive blackhole at the very centre of this AGN is producing relativistic radio plasma making this galaxy very bright in radio continuum. VLA image at 1.4GHz (in blue) as well as at 5GHz (in red) show a bright emission from the central region of the galaxy as well as bi-polar bubbles extending roughly in the north-south directions. Interestingly the position of the blackhole or the origin of its jet emission is seen as a bright point source in a high resolution image made with the VLA at 8GHz (in green). The plasma jet, probably directed in the east-west direction seems to have lost all its energy hitting the dense gas in the disk. Also there is an young starburst in the central region. Combined affect of the plasma from the jet and a possible young starburst driven Superwind is driving away a massive outflow of hot, warm, molecular and neutral atomic gas, and relativistic plasma perpendicular to the disk of the galaxy. Such outflows supply almost all metals to the inter-galactic medium.
