ARG0002g3b, hosts, morphology?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0002g3b, which appears to possibly be a #bent #triple and a #compact. This ARG field is centred slightly WSW from the co-ordinates listed left, as there is no photometric object detectable at that position.

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

    The centre lobe, possibly the host of a #bent #triple, is centred on an ALLWISE source, ALLWISE J103834.90+182904.6. This object has a related Wise Band 1 contour at this location, and the possible connected First emissions are to the NW, with a corresponding faint lobe to the SE. There are no corresponding Wise Band 1 contours for these related First emissions, and there appear to be no radio references in NED nor Simbad for these lobes at their locations.

    What appears to be a #compact First lobe to the E, has a corresponding Wise band 1 contour and an ALLWISE reference ALLWISE J103837.47+182909.5, at this location. There are no radio references in NED nor Simbad for this First emission at this position.

    In terms of radio references in this ARG field, there is a radio reference in NED for SDSS J103836.24+182917.9, which has a z_ph=0.746 ± 0.1150. This galaxy is centred between the NW and E First emissions, more siding with the E lobe, has a corresponding Wise band 1 contour at this location, and is quite visible in the ARG image left.

    Furthermore, there is another radio reference in NED for SDSS J103833.07+182927.9, which is listed as a star, and has a SDSS DR6 z_ph=0.762 +/-0.158. This object is on the ESE edge of the First NW lobe.

    Finally, there is always the possibility that this ARG field could contain separate, unrelated, First emissions.

    As always, comments, suggestions, welcome.
