ARG0001cfs - a big triple, with a strange spiral as host?

  • JeanTate by JeanTate

    This is one of the most difficult candidates I've worked on! SDSS J094348.17+363540.8, z_ph 0.141±0.0162/0.155±0.0337, is indeed a somewhat strange spiral:

    But is it associated with the diffuse radio emission detected in FIRST and NVSS, in ARG0001cfs, which appears in the SE corner of this overlay image? And is the one point NW lobe HAndernach refers to the tiniest of red spots (to the NW of the candidate), or is he referring to the radio emission coming from near the candidate itself?

    And that ~4" offset? Here it is:

    So, what galaxy between the two NVSS sources might be the host (assuming these two sources are, in fact, doublelobes)? How about z_ph 0.354±0.0798/0.312±0.1082 SDSS J094356.24+363325.0?

    Another overlay image coming right up! 😃

    Boilerplate: SDSS image per http://skyservice.pha.jhu.edu/DR10/ImgCutout/getjpeg.aspx, FIRST (red) and NVSS (cyan) contours derived from FITS files produced using SkyView with Python code described in this RGZ Talk thread. Image center (J2000.0) is the galaxy SDSS J094348.17+363540.8; "z_ph" its SDSS photometric redshift.

    Does that help, to decide if SDSS J094356.24+363325.0 is the host or not?

    Sorry I'm a bit lost here. I would have thought that the host was to the bottom left of the group. I'm not sure whose directions are off, mine or Heinz's.
