ARG0003q8g, giant, hosts?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0003q8g, which could be a #giant, #triple, radio emission. This ARG field is cited in the How to describe the radio morphology? thread, and has an ARG cross reference, ARG0003q3m.

    The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
    thread.     First contours in red, Wise Band 1 lime green.

    A possible host for this emission appears to be SDSS J084759.69+014855.7, which has a z_ph=0.582 ± 0.0492. This galaxy has recorded First flux emission, but no radio references in NED or Simbad. The centre lobe emission is positioned on this galaxy. And if this galaxy is the host of the lobes, using Ned Wrights Cosmology calculator, this emission could be a giant, with a size ~ 3', or 1.186 Mpc.

    There are a couple of other hosts that have been mentioned.

    As per the classification comments left the host for this emission could also be SDSS J084758.88+014819.2, which has a z_ph=0.530 ± 0.0515. There are no radio references in NED or SIMBAD for this object, but there is an ALLWISE reference, ALLWSIE J084758.87+014819.5. And again, if this galaxy is the host of the lobes, using Ned Wrights Cosmology calculator, this emission could also be a giant, with a size ~ 3.1', or 1.170 Mpc.

    And as noted in ARG0003q3m, another possible host could be SDSS J084759.23+014835.2, which has a z_sp=0.573 +/-0.00018. Again, this object has no radio references in NED or SIMBAD but there is an ALLWISE reference just NW of this galaxy, ALLWISE J084759.07+014837.0. And finally, if this galaxy is the host of the lobes, using Ned Wrights Cosmology calculator, this emission could also be a giant, with a size ~ 3.1', or 1.216 Mpc.

    As always, comments, suggestions, welcome.

    Great work! 😃

    I think it's still quite unclear what the host, or hosts, is (or are) ... maybe only a deeper, higher resolution radio image could decide?
