ARG0001ahs #noir, hosts?

  • ChrisMolloy by ChrisMolloy

    Here's ARG0001ahs, what appears to be maybe a #one-sided lobe NE and a #doublelobe to the SW.

    The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
    thread.

    In terms of data this is a tough one, due to the absence of any visible ir source for either of the lobes. Possible radio reference hosts for the NE lobe could include SDSS J094128.32+373445.0, a star,

    enter image description here

    or SDSS J094128.84+373415.5,
    a galaxy, with a z_ph=0.550 ± 0.1231.

    Both have radio references in NED.

    Hosts for the lobes to the SW could include SDSS J094125.31+373315.0, a galaxy with a z_ph=0.914 ± 0.1872, and centred on the N edge of the SW lobe,

    or SDSS J094124.73+373311.8, a star. NED has references for both these objects.

    A further host for the lobes, as per the classification comments left, could be centred on or near SDSS J094126.94+373358.7. There are no First or NVSS references for this galaxy, which is in the middle of all the lobes, has a z_ph=0.386 ± 0.1472, and has an ALLWISE reference, ALLWISE J094127.28+373400.2 ~4" to the ENE. There appears to be a faint object at this ALLWISE location in SDSS, but no photometric listing. The middle lobe would have to be #noir, making the other lobes a #doublelobe.

    The apparent host of ALLWISE J094127.28+373400.2, ENE of SDSS J094126.94+373358.7 is shown below.

    So, could this be a #doublelobe with a #noir #compact as the middle lobe, and the host for the #doublelobe being SDSS J094126.94+373358.7 or ALLWISE J094127.28+373400.2? Or maybe just #one-sided NE, with no apparent ir source, and a #doublelobe to the SW, with a possible host being SDSS J094125.31+373315.0?

    Open to any suggestions.
