Radio lightning?

  • Colburn by Colburn

    I can't figure out what this can be and I don't understand if this radio emission is originated from the source at the bottom of the photo or it comes from another place and passes right trough the IR source.

    This NVSS/FIRST contour overlay on SDSS gives some idea of what's going on in this very complex field:

    Leaving aside the possibility that some of the emission may be #artifacts (not unusual in such a bright, complex field), I think there's a single host, z-sp 0.183 SDSS J085815.24+505303.1:

    The radio morphology? I think there are old #doublelobes, somewhat #bent (not nicely aligned across the host), and more recent bi-polar #jets, possibly #restarted, which have not yet evolved to be #lobes.

    Perhaps a radio astronomer might like to weigh in?

    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 J085815.24+505303.1
