    CGCG 292-057 - A radio galaxy with merger-modulated radio activity
    Authors: D. Kozieł-Wierzbowska, M. Jamrozy, S. Zola, G. Stachowski, A. Kuźmicz

    We announce the discovery of a unique combination of features in a radio source identified with the merger galaxy CGCG 292-057. The radio galaxy both exhibits a highly complex, X-like structure and shows signs of recurrent activity in the form of double-double morphology.

    @scientists

    Could you please find out the ID of the corresponding Radio Zoo image!

    It's not easy for anyone to do (find the ARG ID of a field which includes a particular object, assuming it's within the FIRST footprint), and the RGZ scientists do not have any better tools for doing this than any ordinary zooite.

    That said, I have developed such a tool, and will have a go at finding an appropriate ARG field later.

    I had a go, but failed. 😦

    It is possibly somewhere around ARG0000749 - ARG field numbers/IDs are (somewhat) ordered by Dec, and 749 is centered at 58.342, cf 58.3432 for CGCG 292-057. Of course, we're looking for a FIRST radio source, not and SDSS optical one ...

    This galaxy shows up in following new paper (image on page 4), but it is presented as a re-discovery!:

    Discovery of rare double-lobe radio galaxies hosted in spiral galaxies

    Double-lobe radio galaxies in the local Universe have traditionally been found to be hosted in elliptical or lenticular galaxies. We report the discovery of four spiral-host double-lobe radio galaxies (J0836+0532, J1159+5820, J1352+3126 and J1649+2635) that are discovered by cross-matching a large sample of 187005 spiral galaxies from SDSS DR7 to the full catalogues of FIRST and NVSS. J0836+0532 is reported for the first time.
