    I believe that this is a cluster of galaxies. When the galaxies come together gas can get funneled on the supermassive black hole producing the radio emission that we see here. Bent radio sources usually indicate a dense environment that is the result of cluster, group, and /or merger.

    One of the NED Refs is "Mergers of luminous early-type galaxies in the local universe and gravitational wave background" , but in Table 1 this GPair is listed as "non-merging".:

    If the apparent offset between optical and radio is real, this is surely a MOST interesting cluster! 😮
