ARG0000cn8 - two giant ellipticals, each with a 1-sided jet/lobe, on a collision course?

  • JeanTate by JeanTate

    It's hard to say with any certainty*, but there could be two separate radio hosts, each with a core and one jet/lobe. Two of the candidate hosts are close (on the sky), possibly merging, or at least interacting. Is the proximity somehow responsible for suppressing 'the other' jet/lobe of each?

    Oddly, the blue blob - to the S - is only a SECONDARY photometric object (actually three, but they're so close together they're one), a STAR; SDSS J174239.43+544731.7:

    *among other things, the contours are offset from the radio (blue coloring, going white over a threshold)

    I'd go for the two ellipticals orbiting inside a common envelope and distorting the radio lobes.
