ARG0002v74, spiral galaxy, triple, SDRAGN candidate?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0002v74, which appears to possibly be an #overedge #s-shaped #triple.

    The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
    thread.     First in red.

    The host for the emission is SDSS J230456.64+121922.4, which has a z_sp=0.008 +/-0.00001. This spiral galaxy, aka NGC 7479, has numerous radio references in NED and SIMBAD, and an ALLWISE reference, ALLWISE J230456.63+121922.6. Of note this object is listed as a Seyfert 2 galaxy.

    It appears that the NNW lobe is right at the edge of the optical boundary of this galaxy, with the semblance of a faint looping spiral arm just to the NW of this lobe. There doesn't appear to be a host for this lobe at its position, therefore, it seems related to the core emission of SDSS J230456.64+121922.4. However, there are a couple of ALLWISE references at the position of this lobe, ALLWISE J230454.97+122107.5 and ALLWISE J230455.01+122058.5. Other may have an opinion on this.

    First cut-out below.

    Finally, could this be an #SDRAGN candidate?

    As always, comments, suggestions, welcome.
