Here's ARG0000u2k, an extended diffuse #doublelobe centre, and a #compact lobe to the east. The contour overlay below is positioned on SDSS J154620.98+453916.7, which is NNE 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.The host for the #doublelobe could be SDSS J154620.61+453928.7, which is listed as a star, although is also cited as a galaxy in SDSS DR7. Regarding the SDSS DR7 reference, this object has a z_ph=0.513 +/-0.072 and requisite radio references in NED and SIMBAD. It is positioned in the centre of the lobes.
SSE of SDSS J154620.61+453928.7, is SDSS J154620.98+453916.7, which is cited as a #QSO and has a z_sp=0.459 +/-0.00002. Whilst there are no radio references in NED nor SIMBAD, as to whether this object could be the host of the emission, it does have an ALLWISE reference, ALLWISE J154620.96+453917.2.
The #compact lobe to the centre east is positioned on SDSS J154627.14+453947.3. This galaxy has a z_ph= 0.482 ± 0.0415, recorded First flux emission, and an ALLWISE reference, ALLWISE J154627.20+453947.6.
This ARG field has not been imaged in VLASS as yet.
As always, comments, suggestions, welcome.
