NGC 7016 is anelliptical galaxy located about 480 millionlight-years away from Earth in theconstellationCapricornus.[2][3] NGC 7016's calculated velocity is 11,046 km/s.[3] The galaxy has an estimated diameter of about 160 thousand light years[3] and was discovered by American astronomerFrancis Preserved Leavenworth on July 8, 1885.[4] It is also host to asupermassive black hole with an estimated mass of 1.4 billionM☉.[5]
NGC 7016 is one of two prominentradio galaxies in the galaxy clusterAbell 3744 along with the double galaxy systemNGC 7018. These two galaxies form a pair in the central region of the cluster Abell 3744.[6]
NGC 7016 is aFamaroff-Riley type I radio galaxy,[6][7] with bent asymmetric jets. Lower-resolution radio data obtained from observations from theVLA, show a very long, bent extension of the jet on the left side of the galaxy which forms a tendril structure. On the counterjet side there is extreme looping, forming a feature referred to as the “swirl.” It is thought that this swirl which runs into an X-ray cavity produced byNGC 7018, is the result of the jet colliding with the radio plasma fromNGC 7018 and as a result of an interaction with a wake of gas left by the motion of NGC 7018 and its companion galaxy through the cluster.[6]
