ARG0001nrb, extended emission, restarted, wat/triple?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0001nrb, which is a very extended emission, possibly a #wat, #overedge, and maybe even a #restarted #triple.

    thread.     First in red.

    The host for the emission appears to be SDSS J072725.06+310935.4, which has a z_ph=0.250 ± 0.0387. This object has recorded First flux emission, and multiple radio references in NED and SIMBAD.

    Here's a zoomed out ARG contour image of ARG0001nrb, including First and NVSS contours. There appears to be #extended, #overedge, First emission to the NW and SE of this host. This emission is visible in First but not so in NVSS. Whether these emissions are very #diffuse or #artifacts is hard to determine.

    As always, comments, suggestions, welcome.

    Another cool investigation! 😃

    I don't think there's any doubt it's a #restarted #triple. What's unusual to me is that the NW side seems compressed compared with the SE one; perhaps there's a "headwind"?

    The distant FIRST sources seem like #artifacts to me, not least because there's no corresponding NVSS emission.
