ARG0003bny - radio contours overlap, but two unrelated sources! How to indicate?

• by JeanTate

  To the NE is a #triple; to the S a classic #doublelobe. However, the SE lobe of the triple is merged with the NE lobe of the doublelobe, and you can't click on each separately!

  I wonder how many sources like this there are, and how will the analysis of our clicks a) identify them, and b) correctly resolve them?

  Yes, the connection of radio sources is something that the RGZ science team is split on. We would like to click on each separately but we haven't figure out the best way to do this yet, so there will continue to be sources where radio "blobs" are connected.

  Here's what the contour overlay image is centered on (the green smudge):

  

  The #triple to the north has no SDSS host (as far as I can see).

  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 J111809.34+065726.9

  It might be useful to tag this subject as #BHgroup to alert us to the fact that confusion may be a factor here.... Just a thought

  Thanks Ivy.

  I had been reserving #bhgroup for fields in which the radio sources seem to have hosts which are in a (rich) cluster of galaxies; here it's unclear if the hosts are in such a cluster, or even have approx similar redshifts ...

  No worries. As usual, we are slightly behind in going through the tags but any and all hints are helpful 😃

  Here's ARG0003bny.

  

  The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
  thread. First contours in red, Wise Band 1 lime green.

  Regarding the morphology of this emission I am veering towards this being two #doublelobes, and a #compact for the centre lobe. In terms of the #doublelobe to the north, north west, there is an ALLWISE source located on the S lobe, ALLWISE J111809.16+065759.6. so this does not preclude these lobes from being a #triple, with the lobe SE a counterpart of a #triple. This is noted in the comments above. Regarding the SW #doublelobe, there is an ALLWISE source located between the #doublelobes, ALLWISE J111809.38+065724.5.

  If there is a #compact lobe in the centre, there doesn't appear to be any radio references for this lobe.

  Here's the Aladin overlay, with ALLWISE sources red dots.

  

  As always, comments, suggestions, welcome.

  Very cool, Chris! 😃

  I think this is an #overlap, of a #doublelobe (the two south-most radio sources, host ALLWISE J111809.38+065724.5) and an #asymmetric #triple (the other three distinct radio sources, host ALLWISE J111809.16+065759.6).
