ARG0002geb, unusual hourglass and host galaxy

  • ChrisMolloy by ChrisMolloy

    Here we have ARG0002geb, an unusual looking, almost warped, #hourglass.

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

    The host appears to be SDSS J120050.14+182118.1, a clumpy looking galaxy with #red-green-outflows, which has a z_sp=0.472 +/-0.00016. There is an NVSS reference in NED, and It also has an ALLWISE reference, ALLWISE J120050.17+182117.9.

    With reference to the ARG comments left, and whether this is an #SDRAGN candidate, it has a fracDev_g, _r, of 1, and 0.175, and an expAB_g of 0.149 and expAB_r of 0.559, respectively. For c, the inverse concentration index, it has a figure of 0.625 for the g band and 0.341 for the r band. On the above parameters, it could possibly be a #disk galaxy, but the galaxy is very #clumpy, #disturbed like. Maybe a #merger?

    Certainly an interesting looking galaxy and radio emission.

    As always, comments, suggestions, welcome.
