ARG0003fjb: overedge double doublelobe? Orthogonal too?

  • JeanTate 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! 😮

    Contour overlay on order.

    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.

    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.
