ARG0003fjb: overedge double doublelobe? Orthogonal too?
-
by JeanTate
It's beyond the SDSS footprint, in terms of photometric objects, but the host of both the EW distant doublelobes and the hourglass ones seems to be an elliptical at ~(217.0708, 5.6018). Here's an SDSS Chart image:
And a FIRST cutout:
What's weird is that the pairs of double lobes, if they are indeed from the same host, are ~orthogonal to each other! 😮

cool. are these at the same redshift?

Although this - and a whole lot of other objects - is not a PO in DR12, it is in DR7; it's zsp 0.112 SDSS J142817.00+053606.7. SDSS J142817.31+053600.9, zph 0.111±0.013 (or 0.110±0.015) is the smaller neighbor:
It's one of 18,285 objects in Best&Heckman (2012), one of 1,040 in Lin+ (2010), and one of 2,496 in Wen+ (2009). The Lin+ (2010) paper is perhaps the most pertinent here, but even it does not seem to note the possible, more distant, double lobes.

Close in:
Zoomed out:
Lack of emission in the NVSS image, from the "E lobe", suggests that the FIRST emission is not real. But is the W radio source a lobe? Or a completely unrelated source? Maybe a zoomed-in contour overlay of that "lobe" might help?
The contour overlay images in this post were created from sources, and using methods, described in this RGZ Talk thread.
