ARG0000upb, extended triple, giant, hymor/hybrid, restarted?
Here's ARG0000upb, which is an #extended, #overedge, #triple. The contour overlay image below is centred on SDSS J155806.87+451955.4, which is SE of the ARG co-ordinates listed left. This ARG field is cross referenced in the following ARG field and threads; ARG0000uqy, Finding the Giants (NVSS), and the Search for HyMoRS thread.
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 emission appears to be SDSS J155806.87+451955.4, which is a red galaxy. There are a number of redshifts cited in the ARG comments left for this object. SDSS DR14 lists it as having a z_ph=0.627 ± 0.0438. It also has recorded First flux emission, and an ALLWISE reference, ALLWISE J155806.94+451956.0. The emission appears to be a #giant, with a size of 1.2 Mpc, and in terms of morphology, could possibly be a #hybrid, and even maybe #restated.
As always, comments, suggestions, welcome.
Very nice! 😃
As noted in the Comments, the NW lobe is unusual, with diffuse emission well beyond the hotspot.
