Radio Galaxy Zoo Talk

Has anyone come across an object like this before?

    It may be an almost unique class! 😮 😄

    The radio morphology, if real, looks like a jet, or a one-sided lobe. The apparent host is a local, compact (i.e. small) "blue pea" (i.e. spectrum dominated by [OIII], H-alpha, and [OII], with no highly ionized species) ... with what may be green plume(s):

    (I'll resize the spectrum later)

    Two of the three refs in NED are interesting, Sánchez Almeida+ (2011), and Huertas-Company+ (2011). I doubt either ref has anything on its radio properties.

    So, why is this so very unusual, IMHO? Because peas - green or otherwise - do not have radio jets or lobes! An intense starburst does not produce jets/lobes, such features come from SMBHs, and usually only in quite massive galaxies (peas are very light-weight).

    What do you think?

    This may be the same object as the peas but at a different redshift, making the colour change. I agree, interesting either way.

    Maybe quite unrelated?

    The image in this post was created from sources, and using methods, described in this RGZ Talk post. The object at the center of the image is SDSS J151356.33+572523.1

    Looks to be unrelated in this image.
