ARG0003lab, unusual emission, morphology, hosts?
Here's ARG0003lab, an #unusual emission. This lobes in this ARG field have been tagged as a #nat or #wat, but could also be an atypical #triple, or #doublelobe, with an associated #compact lobe. The contour overlay image below is centred on SDSS J143822.81+034017.0, which is WSW of the ARG co-ordinates listed left.
The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
thread. First in red.
A possible host for the emission is SDSS J143822.81+034017.0, which has a z_ph=0.343 ± 0.1097. This galaxy is almost in the centre of the lobes, has recorded First flux emission, as well as radio references in NED.
Another possible host for this emission is SDSS J143821.86+034013.2, which has a z_sp=0.225 +/-0.00004. This object has radio references in NED and SIMBAD, and an ALLWISE reference, ALLWISE J143821.84+034013.7. This galaxy is in a #cluster environment, and is positioned in-between the centre and western lobes.
There is a radio reference for a galaxy positioned in-between the centre and eastern lobes, SDSS J143823.63+034022.4. This object has a z_ph=0.369 ± 0.0492, a radio reference in NED, and an ALLWISE reference, ALLWISE J143823.64+034023.0.
And finally, there is a radio reference in NED for SDSS J143821.30+034013.3, which is positioned on the core of the west lobe. This object is listed as a star in SDSS DR14, and a galaxy in SDSS DR7. SDSS DR7 cites this object as having a z_ph=0.464 +/-0.138.
In terms of morphology and host/s, whether this emission is a #nat, #wat, #triple, or #doublelobe, with the east or west lobes being separate #compact sources, or alternatively, even three separate #compact emissions, is hard to ascertain. Others may have an opinion on this.
As always, comments, suggestions, welcome.
If there's more than one host, maybe we can add #overlap too! 😃
This is a quite unusual source (or set of sources); I guess we'll have to wait for a higher resolution observation to understand it better, perhaps VLASS?
It doesn't appear that this has been imaged in VLASS either.
