double lobes?

  • HannaViolet by HannaViolet

    Are these just two irregularly shaped radio lobes? Which is the IR source?

    Welcome again to RGZ, HannaViolet. 😃

    This is (or might be, it's just my own opinion) an #overedge (there's radio emission which goes over the bottom - S - edge) #triple (three components, called #core and two #lobes). You can see the rest of the radio emission if you click on the FIRST link below the image:

    The host galaxy - in which a super-massive black hole is "active", creating all the radio emission we see - is SDSS J130732.29+440325.3, which has a spectroscopic redshift of 0.202:

    To me, the lobes have a somewhat strange morphology ("shape"); the axis of the top (N) one points in a very different direction than the bottom one (which points back to the host, more or less). I called such strange lobes #slipstrike, after the geological feature.

    Hope this helps and happy hunting! 😃
